I finally race my brother! The one who beat me so bad I built the AWD 4 Rotor 

Bro prolly forgot completely about that race and Rob has built a RU-vid empire on it 😂

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!

Watching Rob drive is honestly more stressful than my day to day life. I love him.

If nothing else, you have created one of the top 10 best sounding engines of all time, so, there's that

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!

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.

lol you can definitely tell he's Robs brother as soon as he starts laughing. They have the same laugh. How adorable.

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

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!!

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!

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!

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

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

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.

This youtube channel is Rob's villan backstory

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

Shout out to Adam Jaybay and Gridlife for allowing you a safe place to develop the 4 rotor!

Personally I’d love to see a 3-4 month stint of just 4rotor focused content

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

Please rob for the sake of my sanity stop coasting with the clutch in into corners

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

Love the additional camera angles! Love the battle of the brothers

The C8 leaking coolant because of the jug in the trunk has to be the most hilarious thing of this session! 😂😂😂😂😂😂

It's always a good day when there's an upload from this channel. It's even better to see three of Rob's toys at the track at one time. Not to mention with sibling rivalry!

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

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.

Jesus that Dahm laugh🤣🤣🤣I love it! So rad to see you two on the track together🙌✝️❤️

Rob YOU are living MANY peoples dream ! Thanks for taking us along !!

Glad I got to meet you and Isaiah at the event been watching since that infamous 3rotor vs gtr hopefully next time y’all come through my fc will be good 🤙🏾 Ps thank you for being the same guy we watch on video they say don’t meet your idols rob is as humble as they come appreciate the convo!

I enjoyed that. Obviously learning a huge amount. Obviously you can both improve with pro coaching. LOVED to hear that the 4-rotor will get the things it should have. A truly great episode with all the guys plus the Rob clone! Superb.

Looks great! Congrats on making it!

The fact that you've build a Masterpiece of a car, but haven't bothered to put a side mirror, is the most Rob Dahm thing I've seen in a while!

We need to crowd fund Rob some driving lessons. Love the guy and want to see him full send.

7:47 your can hear an 787B fly by, exact same sound. Its insane man

Superb video! Looking forward to seeing those lap times come down, and also finding out how the FC goes eventually!

I don't know how you can have so much patience and not give the thing full beans. I just wanna see this thing screaming as fast as it can go. The wait has been so long!!

Such a blast! Seeing much more tire smoke! Fab Daddy had a great Convo with the track official about the safety side of building a racecar like the 4 rotor.

So enjoyable seeing your journey and your humility Rob you've learned so much about building and setting up cars and you are so self-aware about what your gonna learn next its great veiwing keep at mate ..

Both brother's Laughing is amazing :)

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.

Littery thought to myself 10mins ago, I hope Rob uploads this weekend. Love ya bro. Cheers!

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.

The recent glut of on-track footage from Gridlife events has been amazing. Love it.

It was great to have met you sir.

It was a blast watching this thing Rip through the track! Sounds amazing in person that backfire is super impressive. being up in the flag tower was awesome!

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

absolutely love the sound of the 4 rotor, like a screaming banshee

Sounds so amazing 🤙

Man I love the long videos the Dahm crew never disappoints

That was great to watch ! Nothing better than having competition with your brother because you've been doing competition with your brother your whole life and from what I've seen you sealed the deal on that!! Great f-ing job Rob!!😛😛😛😛😛

He's living the life for sure. I love it !

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😎👍🏾🔥

its been so long since i seen kev on a video glad to see the brotherly competitions back

Dahm brothers, don't ever change! You guys are awesome!

THE VIDEO WE ALL BEEN WAITING FOR!!!! You the goat rob!

When his brother started talking after the C5 DBW shit itself, I got really confused until he finished his sentence and I realized that's not Rob lmao his brother had a Rob moment

I'v been watching the build since the beginning... The videos used to be far between.. love this build too, super dope

Badass video. I'm looking forward to seeing the car with a front end on it

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.

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

Congratulations on the 1 million subscribers

The Dahm laugh should be trademarked 😂

It’s nice seeing this kinda sibling rivalry!

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.

Loved it .... great show !

CONGRATS ON 1MIL ROB I DIDNT NOTICE TILL NOW

This is definitely one of my favorite videos

it sounds amazing

Pretty bad ass watching this build come together since day 1...the sounds this thing makes is insane

Congrats on 1 Mill btw, just in time to race your brother

congrats on 1M!!!!

It's amazing the gauges still work in the c5 with the rotory swap I've been here since the RX7 3 rotor days half mile and the drag races the three rotor is still my favorite car along with the four rotor too. Love the content. Congratulations on 1 million subscribers

Sheesh this thing sounds amazing!

Man the 4 rotor is such a beautifully violent machine. I cant wait to see when you and the car get dialed in and obviously im along for the entire journey.

Those sounds are amazing

Go on rob ! 👍great to see you enjoying them, an to kick your bro’s arse is a lovely win.

i love how easy it is to tell that you are brothers!!

He drives like a gawd damn grandma, shifting before red line always. Cmon man.

exciting video, loved it. keep it up ;)

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

it sounds so beautiful

Great to catch a glimpse of me in a Dahm video.

Wtf! That’s me in grid at the top of pit lane. So cool to be in the video, watching you guys wheel together on track was awesome!

I work at AutoZone in Michigan and the other day robs Dad brother and nephew came in and got some stuff they needed for a project. I was WAY to excited to see that last name. Their faces look allot alike.

More than changing the intercooler, you probably just need to help the air get out now that you have helped so much get in with the ducting🤔 It’s awesome to see them all out getting used tho👌🏼you must be stoked!

My man with the VOYD shirt!! 👌

Hey I want to say that you have a wonderful car, great setup and I’m loving even more that your help to keeping the rotary engine alive. My only wish is I would love if you can say in the revs just a little bit high and able to keep control. But again much respect for you building this beautiful machine. ROTARY POWER FOR EVER

This is years in the making🎉❤

Love that your brother has that same goofy laugh as yours 😁😁😁

28:54 I could listen to that all day!

Ohhh man what a beautiful beautiful sound coming on that 4 rotor build...🤤🤤🤤

C8 has a track alignment settings. GM tuned the alignment for track use. All you gotta do is adjust it

Rob, I'm glad I was wearing my earbuds while watching your vid. Your AWD 4 rotor gave me an eargasm.

The best "get one back over your brother" story EVER 👊🏼 incredible build and story

That second run wa more like it, getting after it!

Ayee that's my outback in the cut to the car showcase @1:06 and me in the plaid @1:44 lmao I talked to you for a while and asked about swaybar plans too, i tried to stay and watch the car on track but we had to leave for home before you were on

This is the ultimate moment we’ve all been waiting for. Not that the journey hasnt been memorable

thanks for the outside views at the end. the car sounds friggin amazing.

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
