Jumping my Off-Road R32 GTR

[@MX304]

Splitting the travel 50% bump and 50% droop is a good starting point for a car like this. WRC cars usually run closer to 30% bump 70% droop. That is due to wanting the car to have a lower ride height for high speed cornering / handling while having enough total travel to soak up big jumps. They are limited to something like 320mm / 12.5" of overall travel. Before they were restricted it was common for a WRC car to have around 15" of travel.

[@AdamLZ]

That's super helpful! Good to know I'm at least somewhat in the ballpark :)

[@Juarally]

Also no BC Junk in any profesional type of racing, the Reiger and BOS suspension technology WRC uses is 30 years ahead of BC, 3 way, adjustable hydraulic bumpstops, adjustable blow off valve... is not only bump and droop is the quality of the damper itself

[@IS300Spartan]

[@fredericoespinoza]

[@andrewsmith4429]

The reason you're getting identical travel length with the wheel and the shock is because the shock is directly mounted to the knuckle. Some vehicles have the lower shock mount attached at a point on the lower control arm - when it's mounted like that you can change the leverage ratio by moving the inboard or outboard. If you move the shock point inward you'll get more leverage, meaning less shock travel for the same amount of wheel travel. If you move the shock point outward, you get less leverage and get closer to equivalent wheel and shock travel.

[@scottex.]

yeah when he showed the shock i realized immediately that, really cool to know

[@toddbrown4185]

Adam, just remember you tend to scope creep projects. This is a safari car, and not a rally car. After the new shocks I’d chill with major mods and save it for a purpose built rally car. Just remember how much you loved the white Evo until it became a semi time attack car

[@JamaicanCowboy]

Thank you to Adam and Jimmy Oakes for ending the drought and dropping videos today! 🙌🏾 My KZbin has been dry af these past few days 😂

[@karterjones9590]

[@TheMRdizzlewizzle]

Cleetus mcfarland solves that issue

[@Ethericbikes]

You gotta round make those lowers bars actually bend under the car! That crazy edge at the bottom of the bash bar probably helped cause that much damage because they just dig into the ground causing damage!

[@saulbttf31]

you would almost never want more compresion than droop, i'd split it about 40% compression 60% droop at least, the idea is that having more droop makes the tyre touch the ground earlier while landing which gives you more time to slow the momentum and soak up the bump, also if you run that much compresion on the front you are in danger of landing with the slightest steering and destroying the fenders. if you look at wrc cars they have the wheel arch cut much higher so at full bump the tyre never hides behind the fender, since you are not going to cut that much of the fender i would recomend either lifting the ride height a bit, or at least not allow as much bump, you could probably run the longest shock that you already have and just lower it with the preload, giving it as much travel as possible while limiting bump travel. hope it helps.

[@DxCBuG]

that makes so much sense - my hot hatch really has lots of droop which i noticed changing tyres with a jack. It really does not have much on the compression side of things which i also noticed when i drive to hard onto a piece of road that suddenly goes from flat to a steep incline. It sounds really rough so i probalby hit the bump stops there, but never anywhere else on a rough road :D

[@saulbttf31]

​​​@@DxCBuGHi, to avoid that noise when going into a steep incline you could go to either stiffer springs or a bit stiffer shock on compression, for off-road it's always wanted to have a bit stiffer compression than rebound. A good way to see it is that if you have 60% droop and 40% compression on the travel, you'd want stiffer compression shock. And if you have more compression than droop then you leave them about even. The idea is that the less compression travel you have the stiffer you want the shock on compression to avoid getting into the bump stop. Also while jumping you'd want a bit stiffer rebound on the rear than the front, so it mitigates even more the nose dive which happened to Adam. Hope it helps.

[@RossBobby]

Would have been interesting to have Collette’s opinion on the double stacked jump before he hit it, with her Rallycross background she probably would have spotted that issue.

[@kylepadelford]

Similar to a MacPherson strut style suspension, the coilover is mounted directly on the spindle in the Skyline GT-R despite being double A-arm. So, you are left with a motion ratio that is esentially 1 to1. The only way to change the motion ratio would be to have the coilover mount be attached to the A-arm. Now depending on how far out or inset your mount is, will give you more or less of a ratio. Loving the build!

[@nicolelongneckergallery]

Going to suggest longer static spring height AND higher spring rates. You’re asking the shock to control compression force and the spring rate is where you want control that. Sadly, adding articulation will require control arm redesign. Great content.

[@PBRatLord]

This video has the energy of "I got some 5100s on my 06 quarter-ton, it's a pre-runner now so lets go jump it!" XD You can tune all day dog, some struts ain't EVER gonna hold up compared to properly set up arms and bypasses if you wanna get off the ground.

[@swbpajlife]

Removing the swaybar also adds droop, for an IFS, you remove the front swaybar, which allows the rear to droop (flex) more. We also do an upper control arm ball joint flip, if you can't adjust the UCA

[@johncarlson2255]

If you switch to heim joints and get rid of pressed rubber bushings the bind will go away on full droop and your coilovers can react quicker

[@Garage_unknown]

Awesome video, refreshing to see something different done with a r32. On a side note, glad you took the block height of the spring(s) into consideration. It is a factor that is often overlooked, yet so important.

[@Barry.ONeill]

For rally Cars even tarmac rally cars (theres alot of jumps here in Ireland) A good rule of thumb is 1/3rd for compression and 2/3rds Droop , you want the wheels to touch the ground asap when landing over jumps for an smoother landing 👌💯🤙

[@cadenmartin2849]

The reason you have the same shock shaft to wheel travel is due to where the shock is mounted, if it is mounted to the spindle you have a 1:1 movement ratio, when you mount the shock to the lower arm then the movement ratio changes due to the control arm acting as a level.

[@Criscitiello]

The R32 sounds so good ripping up to the ramp 😮

[@zakswindle]

Having built my own control arms for my Duramax, your ball joint angles are going to bind. What you can do is cut off the section of the control arm that ball joint presses into and weld it at a steeper angle. You will need to add some support material to the area that was cut.

[@J4rn0]

Im pretty sure you are supposed to maintain alot of throttle even in mid air. Looking at alot of rally footage, mid air they are always bouncing off the rev limiter. Also keeps the weight on the back wheels till the last moment, this avoids tilting forwards in midair. Also it avoids extreme engine braking on landing (thats why you have the skid marks on the floor)

[@colindevlin4567]

That’s true but it totally depends on wheel speed matching your actually speed, you don’t want to over rev the engine on landing and absolutely destroy your drive train, that’s why you always hear rally car drivers bouncing it off the limiter over a jump because they’re pushing the car to the limit. Adam wasn’t so there’s no need

[@kolapodasilva5838]

So many thoughts: 1. Skidplate is the real MVP of this episode. 2. I vote for proper rally suspension. 3. Absolutely ripping in Dirt Rally! 4. "Extra, extra long!" (IYKYK)

[@seth3978]

This might be my favorite build Adam has done since I started watching, four rotor Supra is definitely a contender though

[@BillStraub303]

in the clip showing the suspension cycle it looks like the shock attaches to the knuckle, so that's why the measurements are the same. It would have to attach to the arm for there to be a travel increase at the wheel end.

[@cumbob]

What I was thinking

[@Epitome1]

preload brakes before ramp release on the ram/lift off, helps with keeping a level car for landing! play with the release time for better weight transfer midair

[@SwiftSloth]

Im not gonna lie, I'm trying to recreate this build on fm7. I've realized that it will take a while, which goes to show how unique of a build the safari gtr is. Legit one of the most exciting builds on YT at the moment. Love from Ohio :)

[@offwhitecolby]

i know a-lot of dudes will eliminate a sway bar for off-roading or change away from the factory style to something like an adjustable sway bar.. often times you can loose droop and up travel because of your sway bar. you may have to increase in spring rate to accommodate for the increased body role

[@fshfsh4345]

When launching off the jump, rally drivers slap the brake pedal a few feet before the lip then get back on the gas before jumping. This allows the body to pre load foreword then by hitting the gas you effectively lift the front end and help prevent nose dive. This is how they stay level over 50ft jumps and off kilter landings. Maybe this can help with your adaptation into the rally trails

[@brianharris8441]

[@adampittman508]

The faster you go the smoother it’s gonna be. Great job looks and functions equally awesome.

[@tb_fifty3]

Stacking springs in series will give you a combined rate which is softer than each of the individual rates. There is a forumla for this. Offroad guys will have a collar above or below the spring seat intermediate that you can tune the crack point with the height of the collar. Using the stacked springs will give a soft ride, but once the intemediate touches the collar its then only using one spring which gives you a higher rate than the two combined which is ideal for jumps.

[@Danger-Dave]

Adam lets his inner Evel Knievel take over when he's around ramps (Shawn knows this). I love all the data crunching and thought process that goes into finding success in any suspension setup for a given duty. The one thing I'm missing here though is... what are the spring rates, and are they the swift springs or regular?

[@seanmc92]

Honestly, bc dampening is great. I jumped my sti with dr coils somewhere north of 120 mph and the landing was ridiculously smooth. Whatever way the road was, the speed and balance of the car matched perfect and it landed so nicely, i was extremely surprised.

[@Laterdays2]

You have to lose big to win big. No regrets. Gotta love your attitude.

[@AngelDiaz-jd5nt]

As soon as your rear wheels hit the ramp it makes the front of the car go forward because of how its angled and how short the ramp is. If you were to extend the ramp to maybe twice the length itll give you more space for the car to launch straight or even have the rear land before the front

[@benpipitone4048]

Careful for CV bind with too much droop. A known solution besides just an off the shelf high angle cv axle is 934 axles. A stock 4Runner axles for example has 21 degrees of allowed motion but 934s have 28 degrees. This translates to substantial increase in droop travel. To use the 4Runner as an example again they have about 8.5” of front wheel travel from factory but a +4” upper and lower control arm paired with 934 axles can pull anywhere between 14-16” of front wheel travel. Not being double wishbone will obviously change things but doing some experimenting with machining high angle axles would be really cool.

[@andrewseay6233]

On full droop on the rear. Loosen all the control arm bolts and re tighten at full droop. The control arm bushings are probably at their limit and holding the wheel up.

[@Markthegreat6789]

Bring on the offroad content! Most Ultra4 guys set their compression/droop as close to 50/50 as they can get without increasing their COG. They need the compression to keep the car in control through the high speed whoops. Rock crawler buggies aren't designed to go fast so they want way more droop than compression and get their COG as low as possible.

[@goncalocorreia8489]

Hey Adam, just a little thought here, when you re hitting the jump if you are hard on throttle(acceleration) is gonna make the back shocks compress right before taking off wich will then shoot the back of the car up and nosedive it a little, so maybe try reaching the ramp with good speed and keep like a constant speed with less throttle so it won’t compress as much in the back

[@ilike2watch66]

You know you have a BADASS Woman when you tell her about jumping your car and she has the wherewithal to tell you what you did wrong!!

[@lucasdamask]

i think a drivetrain drop of a inch would make a world of difference on those axle angles and also help you increase the droop to more than the bump, since it makes the car more stable in uneven terrain at speed, Rally2 and WRC cars run like 60/40 and 75/25, droop is everything in uneven terrains and jumps, that is why you see with high speed off road cars like WRC and even pre runner trucks, they have waaaay more droop than bump. if you look at them in the air they shoot the wheels down so much that they get some extreme positive camber from droop.

[@JK-tu1xx]

Regular coilover suspension is not designed to take jumps, it really doesn't serve a dual purpose like you're attempting to make it do. The main issue you are going to run into is reliability of the shock absorber, a long skinny plunger is going to snap with torsional stress (angled and hard landings). That's why off-road oriented suspension uses significantly larger components, they hold up to the stress of a lot of impact absorption and have the rigidity to handle the torsional loads placed on the components.

[@youngboyslick7196]

Same as jumping a dirtbike. Smooth throttle through the jump. If you let off early you nose dive. Gun it last second you tip the rear

[@scottmdix]

all i could concentrate on the go pro, is the intercooler piping moving around and the little rubber guard floating. She Jumps good

You can also go into the ramp off throttle and then for it as you go up the ramp so that is loaded in the rear and the front is unloading to do the nose up

[@ahmadalashat8768]

From enduro dirt bike riding .. you can clutch it or just gaa it before the jump to create a little wheelie so when you hit a short ramp like that the front will lift and thats where is the most of the weight in your car.. so its doable on this ramp with same setup

[@samlallo5747]

I'm not 100% sure I know what I'm talking about but the reason why I think the rear suspension is sticking is because of the sway bar end links. They need more travel when you get a higher lift. It will make the car feel looser but also stick to the ground because you have more travel. Also, I would have less compression like 40 and 60 droop. Also having more travel in the rear is better for most suv and trucks but idk about car. Love the GTR Adam

[@samlallo5747]

[@kittycitykevin]

You’ve just started down the off-road rabbit hole, next is articulation through sway bar end link disconnects, off roading requires independent movement of all 4 wheels!

[@cadenmartin2849]

If you want more performance from those shocks then you should pull them apart and re-valve them for more off-road abuse. Just from that jump the rear needs rebound pulled from the rear and rebound added to the front along with compression added to the front

[@expert4009]

The reason why the front end fell down so hard on the double jump is because you let off the throttle aswell so all of the weight transfered to the front. Thats also probably the reason why most WRC cars keep it pinned on redline when jumping. (edit, didn't get far enough in the video to see him acknowledge that.)

[@joecosta3416]

I don't really know what I'm talking about, but it seems a factory R32 GTR has around a 60/40 f/r weight distribution. Would it make sense to get the chassis on scales at the front and rear with Adam in it (maybe at the chassis and not at the wheels?), and add some weight to the rear to help keep it more level in the air? Sounds like other factors might play into it more, but feels like that'd help right?

[@tjbmx1883]

King makes some of the craziest off-road suspension on the market. I’m sure they don’t make a kit for an r32 but you could definitely fab some brackets

[@zane_dalton]

[@VdubSPAZ]

To give you some inside knowledge I'm sure someone else will give you the same thing I'm not sure how many people here know about it but you have to know the weight of your vehicle front and rear and then base it off of that for your valving of your suspension that way your shocks will know how much they have to take not only for dampening but also for Rebound bless your spring rate will also be a factor in that because if you're over sprung that's not a good thing but you can also adjust things by knowing the weight and then a valving the shocks based on what you need or struts

[@_jdanyal]

The rear binding is likely coming from the LCA. It’s a common thing on the r32/s13 rear subframe. If you lower the forward LCA pickup point it’ll help. GKtech makes a kit for this 👍

[@SpencerPhillips-py4wx]

Well 30-40% compression 60-70 droop for slow speed although I run 14” shocks with 3” compression and 11” droop Higher speed. 50-50 or 60-40 works
