Great vid, with awsome info. How many sets of coils would you plan to go through until you land on the right one? Had the car weighed and sent the weights off to dobinsons with the intention of landing on 3"-3.5". Got the springs and the front sat at 2" and the rear sat at 3.5". Secondly, how do uou calculate how much up travel to maintain vs how much down travel? Just got new 12" shocks and have maintained 5ish" up teavel in the front. Or would it have been a better idea to loose 1" of up teavel to gain an extra 1" down travel? Was also finding that with the 12.5" or 13" shocks the drag link was binding.
@mattkinsela2 күн бұрын
I’ll usually get it right first go, but it’s pretty easy with coilovers. Working with normal springs sucks when you’ve got to send the info off to another company and hope they do the right thing and pay them before you find out. It’s a bit of a compromise with ride height vs uptravel, something has to give, if you want it low there’s no room for uptravel, 6” might make it a monster truck but in some cases you can make it work at a good ride height

Couple of topics for when you are at the shock shop. Target spring frequency for say rock crawler, weekend warrior, tough tourer, desert racer. How and why rebound is more important than compression. Any reason to not use a torsion bar from an ifs car as a swaybar. Ive got a mazda bravo torsion bar in the front of my patrol. Cost $50 and has way better flex than superiors superflex bar. And just as stiff.

Very useful info. Been thinking of changing my setup a bit and reminded me that i did up the compression to help with body roll a bit. And thinking maybe i can bit better ride on the road by softening them after adding a sway bar. Would you recommend upgrading the front or rear sway bar first? Was thinking the rear? For reference i have an 80 with 2 inch lift, rooftop, rear bar, full drawer with water tank, so a bit of weight. Does have 500kg springs in the rear. Bought them as the 250kg ones were sagging.

Loved this video mate. It’s interesting for me coming from a Downhill bike background and having that understanding of high level suspension tuning and sprung/ unsprung weight, and seeing how that converts to Cars where things like Beam axles and sway bars exist. I found your comments on Hydro bumps really interesting. I remember watching the Skid Factory where they installed them for a Patrol/ 6BT conversion purely for the additional engine weight on compression and wonder if that was necessary or if correct spring rate/ shock valving was the appropriate answer.

Loving the content mate. Great to see a no bullshit information video that isn't biased due to sponsorship. I have a question in regards to swag bar links. What the best way to work the length? Just take it for a drive and see what length works best or there a particular way to work it out?
@mattkinsela4 күн бұрын
Cheers mate! I was abit unsure about this one cause it’s a pretty dry topic unless your into it. This is could have been a lot longer but I thought no one would stick around haha. If it’s in a standard setup, usually I just go full bump and full droop and see if there’s something that will limit the bar, like on a patrol rear, short links make the bar roll back and hit the centre on droop, but long links make it roll forward on uptravel and hit the snout of the centre, so you really need to find the length that works in the full range. Ideally your aswaybar arms would be pretty much level at half travel, but that doesn’t always work in a standard car setup

@@mattkinsela thanks for the reply mate. Yeah that makes sense. In my particular case i have an 80 that use to have big lift but I've taken it back down to 2 inch but because I'm still getting familiar with the 80 I've been unsure if it was ever changed from factory length (being that it was 4 inch i would assume it would be different). But I'll be checking that today. Thanks again mate keep the awesome content coming.

Some useful info here Matt. What's your opinion on front vs rear sway bars on a coil front lead rear setup? Either removing or upgrading one or the other in order to get the leafs to move more? Or is this viewed more as a rear spring rate issue?
@mattkinsela4 күн бұрын
It depends on the suspension and what you want vs what the springs are, I used to run a sway bar in the rear of my coil front leaf rear Hilux as that’s where I felt it needed it. But not all will be the same. Most leaf setups are pretty good at resisting roll already lol

Absolutely loving the series! Just had a question with the angles you have designed for the panhard/steering link, because both are parrallel not just to eachother but also almost parallel with the ground, does that mean you suspension will have less ability to compress? Ie if you hit a bump at speed your suspension would compress a smaller amount compared to a setup that the panhard and steering link were further from parallel with the ground (while still being parallel to eachother)? I hope I've worded this correctly and it makes sense Please keep the technical information coming as well, this is awesome!
@mattkinsela15 күн бұрын
Yeah I understand what you’re asking. No it doesn’t, they can swing up past horizontal without any ill effects. (As long as there’s nothing above to hit them lol) The benefit of them being flat and also having similar up and down travel, means the diff doesn’t move side to side very much in its full range, vs starting on like a 40 degree angle and then dropping the diff 6 inches it’ll swing across the car quite a lot!
