i love how Rob and his brother have exactly the same laugh and body movement when they laugh, like slightly leaning backwards and all, really happy you two have that great of a friendship as well!

[@imacaryay7628]

There's a vid a while back that had him and both his brothers going on a cruise and hearing all three of them laugh the same way was amazing

[@trque0fthedevil]

Rob buddy, you’ve gotta stop this bad habit of coasting into corners with the clutch depressed. You’re losing out on the one of the biggest contributors to the cars stability for corner entry in both engine braking AND the decel aspect of the diff. It’s one of the worst things you can do….. I know you’re managing downshift issues, but it’ll make everything SOOOO much better if you stop that terrible driving habit!

[@lucamerlini6377]

I always say the same thing, i hope he can manage to fix it

[@_Colt]

@Rob Dahm

[@zephyr.r]

yes rob, we can tell there’s understeer from not enough engine load on the front tires

[@gpkarter71]

1000 percent correct, and you wanna talk about scary. Having the clutch re-engage with what is a free spinning drivetrain… you’re clutches won’t last long.

[@myronybarra]

Trail braking through the corner will help with understeer because the front tires will stay loaded.

[@shona5512]

I think it's time Rob paints the tube chassis before it starts to rust. Looks like the rain at grid life has started the first stage on the bare steel.

[@mikescherrer4923]

Yep.

[@flyingbaguettefpv]

That patina looks so sick tho, I hope he paints the chassis gold

[@darkwatcher01]

Hope he paints it silver to keep that "bare metal" feel.

[@shona5512]

@@flyingbaguettefpv if he painted it the same bronze colour as his original wheels that would be fine. Personally I'd prefer satin black or silver, but anything is good as long as it's providing some protection.

If you listen closely when they talk, they sound very similar too

[@klm2fm4]

I’m glad they addressed the firewall thing as well as alluded to a new chassis. With as much as they have learned and redone things, I was wondering when this would come up

[@AEasyButton]

Dope to see you getting some more track time! One easy thing you can do to make you driving feel more confident is to stop shuffling your hands on the steering through turns. In other words, keep you hands at 9 and 3 on the wheel unless you actually need to turn harder (some of the tighter hairpins). 1) It makes you laps more repeatable because you hands will always be in the same position during turns so you can feel the differences that you did with your driving lines. 2) You will be able to feel how the car loads the front suspension better cause you hands stay connected the whole time. This will also let you be more confident in the braking to turning transitions. 3) If you do have a little under or oversteer, catching it will become a more natural over time. 4) In the C8 you will always be ready to shift when you start going manual with your shifting. 5) Racer nerds wont pull their hair out when watching :) I teach racing and this is one of the first things I have people do to help them build their consistency and have bigger balls. I hear you are starting to do some sim racing too. Maybe practice it their so you can get accustomed to it. Keep on making that 4 rotor sing!!

[@HectorCabrera]

Couldn't agree more. I mentioned the 9 and 3 hands and to stop shuffling around in his first track outing months ago with the Turbo II RX-7. His buddy that was helping him with instruction seemed to blow it off as being ok, but that's absolutely not true. No need to move your hands from 9 and 3 unless it's a very tight hairpin turn.

[@scotty305]

@@HectorCabrera tell that to Randy Pobst. Here's a video showing him instructing a racer in Porsche which has pretty tight steering ratio, and not once does he mention '9-and-3'. kzbin.info/www/bejne/bKbQl3x3r7V8jLs 9-and-3 only works for gokarts or formula cars, the shuffle method works better for nearly everything else with a production-based steering rack.

[@HectorCabrera]

@@scotty305 In that video, they're focusing on slide control. Sliding and drifting are completely different than tracking your car under control. Yes, sliding/drifting you need to be shuffling around at the wheel. Otherwise, while under control there is NO need to move your hands from 9 and 3 unless it's such a tight turn that your arms cannot cross each other. ;)

[@rainedrop14]

after this video i'm 110% convinced that "robs brother" is just rob from an alternate universe where he kept his "safe" job and didn't pursue youtube all jokes aside, fantastic video, love seeing the 4 rotor finally stretching its legs more often after all these years. And watching you grow as a driver/tuner/everything is just extremely insirping, keep it up dude!

[@Gsr_automotive]

The fact that you guys laugh in the same way is so wholesome. 😂 Made my day

[@euphoric5172]

i just love how the 4-rotor backfires on every gear change, the sounds are just incredible

[@RadDadisRad]

The way the track official talks about the car is awesome. A lot of track officials are not as compromising. He represents what we all love about motorsports and that is awesome.

[@von...]

I know for a fact this car is going to be an absolute monster once the track manners are tuned closer to perfect. Plus you wont ever have to have your left foot leave from the brake pedal, which will open you up to mid-corner partial brake modulation to encourage rotation & what-not!

[@virgilioaponte9756]

Brake migration

[@pvanb291]

Exactly! I did a flat shift setup in a 250cc 2 stroke gearbox kart. So much quicker to leave your foot pinned hard on the gas changing up and not having to use the cltuch to go down the box! Can then just brake with your left foot into corners and know your transmission is engaged all the time. He's defeating the whole purpose of his clever transmission at the moment!

[@ValentineC137]

​@@pvanb291 9:44 it isn't quite working yet lol

[@worldwithoutbass]

[@MalphasMedia]

The fact that his brother has the same silly laugh, makes me laugh.

[@davidblanck4131]

I think the most important part of a build is the "Learning curve" part. Sure. You can pay engineers to dial it in for you. And, that is definitely an option. However, the knowledge you gain now is more valuable than paying someone to make it fast for you. Now you know every feeling, every step, every improvement. Which leads to you knowing your car better than anybody else. Keep dialing it in. Oh, and the experts are right on this one.... get a freaking firewall built lol.

HUGE congrats! The 4 rotor sounds amazing & getting more & more dialed in, all around exciting day. And super cool to hang out & have experiences like that with your brother, really is nothing like quality time with the family

[@MasterTygt500]

road course track days are awesome. glad too see the projects getting properly beaten on and you having fun. Get the 4 Rotor's clutchless rev-matching downshifts working asap. For the power and capability of that car, go with paddles. Keep those hands on the wheel at all times. Also, stop shuffling your hands on the steering wheel. Keep the hands at 3 and 9 unless you really have to turn the wheel that far (you might want a quicker ratio steering rack to reduce steering degree input). But stop shuffling the hands. Harder to save an oversteer moment if your hands aren't always at the same position.

[@the1nicko]

I was going to say the same thing but who am I haha, the hands were bothering me though, hands shouldn't move positions for those small turns. You feel more confident going faster through the turns with a proper grip.

[@Rmx2011]

Love this video, just two brothers having a blast on the track and going at it with their cars! Love it!

[@seppericciardi1413]

You’re doing great keep up the great work!! I’d recommend that you stop feeding the steering wheel when you’re about at 90° it’ll help you have a smoother turn in and cornering

[@17111993DAVE]

I've been watching Rob for years now. Not an og but ever since he 4 rotor was originally delivered to his shop. I reckon that 4 rotor will forever be at 10% finished for the rest of time. It will forever have a hacked up, raggid arse interior, missing panels, never be all the same colour/carbon and always drive like a pig. It's cool and rob is doing a great job & props for doing all this stuff himself but im feeling that car will kill him or we will all die of old age first.

[@white67black28]

So cool you got to be on the track with your brother. Haha, felt the adrenaline when you were catching him with the C8. Glad all three of your cars ran well and you have some ideas of what to do with the 4 rotor to make it better.

Hey Rob, i love your videos my dude that 4 rotor is nasty lol a few years ago, my friend showed me your 4 rotor build. and since then, i was obsessed with your car and the sound and rotaries in general. i have seen all your videos the day you release them. That friend has since passed away. Watching your videos is a way for me to relive those moments with him that ill never get again. Thanks for making this content, you have no idea how much i appreciate it.

[@michaelmain1990]

Good job keeping the tires quiet around corners. The more the squeal the slower your time, but you gotta remember to be in gear and clutch out before the last brake marker.

[@codyrobertson3635]

Seeing the dash back together almost stock is dope. It's just enough race car and it's sick! I need to catch up on some 4 rotor content

[@MarkusFjord]

Big Ups! Just loving this content. A week felt like ages

[@noceilingsmotorsports]

3 things that I find really confidence inspiring as far as driver comfortability is having my pedals, and shifter in a place where I don't have to think as much when I'm performing an upshift or heel toe downshift. On my old miata i had a 3 inch shift knob extension so the distance to the wheel is shorter for faster shifting and less time with my hands off of the wheel. And it also had omp pedal covers so I could move my brake and gas pedal closer for heel toes, and my clutch in a position where my leg is straighter (it was kinda at an angle before because of how small the foot well is). Those two small things alone helped me be one of the smoothest consistent drivers out of my friend group, because it allowed me to focus on driving and let my muscle memory do the rest Hope any of this helps, keep ripping😎👍🏾🔥

[@halofreak1990]

"It's amazing the gauges still work in the c5 with the rotory swap" Rob's taken special care to ensure they still work. Still irks me he doesn't pay the same amount of attention to detail when it comes to the various status lights that are still on (like the traction control and/or ABS) or clearing the engine warnings from the C5 ECU and looking for a way to tie them into the, I think it's a Haltech? Once he's done all that, it'll be as close to perfect a swap as it can be

[@spdcrzy]

The C8 is set up for understeer from the factory, they supposedly provide specs for track alignments to make the handling more balanced.

[@kevinmiller4312]

I’ve been watching you for a while Rob and I love the content as always. I love the fact that you’re not only building a monster you’re learning how to drive it too. However, I have two critiques: someone else said it but I’m gonna repeat it, you gotta use more engine braking into the corners. I know you’re working on the autoblip downshifts but either way, you still gotta be downshifting to maximize engine braking. I don’t currently have a car I can take on track but I ride a motorcycle and I play lots of racing games and the same concepts apply. I’ve found that as I’ve got better control over braking into corners on one I can get better/apply things I’ve learned to the other, and throttle/brake control is everything. I’m not gonna try to explain it because there are several videos on YT explaining the concepts but I can tell you from the saddle of a bike and fighting on lap time leaderboards that braking into a corner while downshifting to keep the motor about halfway through the rev range puts the balance of the vehicle forward which lets you turn in better and keeps the vehicle stable, especially if you can trail brake a little. It also lets you roll onto the throttle at the apex which loads the back end up and lets you get out of the corner with max yeet. Which leads to my second critique, I think you might like longer gearing. I know that you’re not WOT or hitting limiter yet but having longer gearing might help you drive the car better since you’re not shifting all the time. The car obviously makes enough power so instead of having to shift down like 3 gears, if you’ve got longer gearing you might only need to go down 2 and you’d still have max yeet. I got long winded but if you take anything from this watch a twist of the wrist 2. It’s an old motorcycle video explaining how much throttle control effects your riding and I’ve been able to apply to every vehicle since. It’s on YT.

[@braddock87]

[@Generic_661]

From your last drive in the 4 rotor, I get the impression that whilst you're learning the car it might be a good idea to downshift with the clutch, it means you can heel/toe down shift for much less chaotic brake zones

[@itskivoni9551]

[@The.Real.Andrew.Cooper]

It’s nice seeing this kinda sibling rivalry!

[@Anonymus-ih7yb]

A tip for the handling of the C8, Michelin tires have a soft sidewall which can make the car handle sluggish. So either change tire manufacturers or get skinnier ones so that they are a bit stretched.

[@BraydennnB]

Only thing more enjoyable than the sound of the 4 rotor is 2 Dahms laughing 😂

[@giant23]

From driving on a pretty good sim racing setup, with a mid engine car like the Porsche GT3 one thing i learned was that if you brake hard then gas it when going into a turn it will give you just enough oversteer to then get faster lap times and get you around faster then having to battle that understeer. I've played around with that method and I'm no expert but it works for me. Give it a shot!👍 also that's with stability control and TC on.

[@ValentineC137]

try turning stability an TC off and see how quickly that gets you killed lol
