Shout out for Ultimate Auto Protection ninjas who did my full expel ppf and ceramic coating. My car but not my pic. They had a prof take some promo pics for their shop

Looking good Dr. !

Another very noticeable mod to this car is the addition of the toe-links and monoball kit offered by Dinan. After having both toe links and mono balls installed last week, the car is much quicker to jump on acceleration.

Anyone else install these?

Not yet I have my set of them here at the house but need to find a installer. Also waiting for couple other items to get installed. It is good to hear you can tell the difference.

Apex race wheels make huge difference to lighten up the steering.

the one change that significantly changes how the M8 performs.

These are the Apex VS5-RS race wheels previously posted but anodized black. Call it 20 lbs a wheel plus rubber.

Rears are 295s and the little stretch helps preserve rubber when run at 32 psi.

10 mm spacer.

Accredited race licence tomorrow. Will post up a vid

[Dr Thrillride]

Passed the race license but no video because we have an instructor in the car the entire time on track.

My instructor was squeamish as a passenger and told me the story of the hellcat he was in the previous year which did not have brakes that could stop the car on a road course.

After he settled in, he was very surprised at how nimble the M8 was. Again wheels and KW V4s.

[Dr Thrillride]

Rant on: I’ll probably delete this later.

I get a bit defensive if not combative about people that laugh at the M8 on the track. All the talk about the smaller M cars being so much more nimbler and better for the track. If you were to ask any of the M2s, M3s, and M4s owners that have been on the track around my M8, they think differently now.

I think people actually mean to say, that M8 is a lot of work on the track. Agreed. But who’s afraid of a little work?

I have not met the new M3 on the track yet, but the new M2 and the hotshot driver at the track today was sure looking hard at the M8 after he got handed his azz by the M8.

Nice guys but talk about full of themselves and their track-purpose M cars. To boot, I’m running Hancooks, the slowest R compound DOT tire out there, running traction control, turned the racechip off because it’s not needed. By comparison, the M2 has ground effects camber plates, race wheels, cup2s, exhaust, downpipes, intake, all the goodies. Nope, could not run close to the M8 and his line was good.

I love BMW owners and the cars they drive but wtf is it about the disrespect the M8 gets on the track? This is why I love this car so much. It is literally a Jekyll and Hyde machine.

Last weekend I was also on the track and it was pouring all morning. Very surprised to see a GT4 RS, yes RS version, with absolutely no traction out there. Running PS4s. Could not put power down. Has me worried now about my build that’s coming soon. Not sure how a rain tire would work but I wouldn’t be carting around a second set of wheels for a rainy day. It was a blast in the rain. Again, M8 gets big thumbs up for handling whatever is thrown at it. Advantage to the M8 and its hefty weight to be able to run very smoothly in the rain.

I'm not saying that you will see the best results from an 2wd dyno test but I see zero reason it cannot be done. Hell I've done standing burn outs and donuts in 2wd with nothing happening, so the theory that wheel speed sensor on the front causes it to launch back into AWD (that is what I've read on the net) is total bogus. I did just check you can enter dyno mode and then select two wheel drive as well.

Anyone actually explain why this cannot be done??

If you can do a standing 2wd burnout till 120-130mph, then you can dyno in 2wd with no issues

I've seen the comparison of doing a burnout to 2wd dyno over the last 5 years and it does surprise me that no one has paid any attention to how different those two actions are in terms of speed.
At best you can get the rear wheels to spin the speedo to 20-60mph? in a standing burnout. Compare that to a dyno session that goes to 120-150mph.
That's the real comparison!

does anyone know how to embed this video, for those of us that can't handle the forum software

[Dr Thrillride]

GT3 RS whilst on the track yesterday. Great guy, really good driver. He just got the car and was doing a 1:48 on his first set. My best time is a 1:46 with Cup 2s, not these Hancooks, no excuse, but they're just known to be slower. P driver slowed down for me somewhere in there and his tow made me a bit quicker than I'd be on my own. We did a lead-follow thing which really helps to learn the course from one another. Awesome day.

I did not edit the video so it's a bit long, but for your viewing pleasure. Note the different lines of the two cars. The P-car is just friggin amazing. Nothing like it. I have more vid chasing a built-up lotus and too much fun.

Great vids and lot of good info.

I am also a former bike racer starting in the 1970s and raced in Ontario with some of the greats. (I was never close to great. ) Last "real" race was the Victoria Day Sprints in 1987. Did probably 100 or so track days on bikes after that though until about 7 years ago.

So, I destroyed my nearly new M4CX at WGI at the end of July and ordered an M2 10 days later. (I wanted another M4 but but I was underinsured and can't presently rationalize the $15-20K additional funds need for another one.) That M$ was a beast at the Glen, and I saw 147 MPH just before braking for the Bus Stop.

I just found out that my M2 build has been pushed out another 9 weeks due to production issues with the carbon seats, so I was searching out other options.

Straight out of the blue a sales rep sends me a link to a 2020 M8 for about $80k with 32k miles. That got me thinking and I ended up here.

Always loved the M8 but never thought it could be a competent track car.

Now I'm looking at used M8s with 20k ish miles for just over $70k, which is LESS than my M2 build.

Its hard to argue against 617 HP and 2.5 0-60.

Anyway, keep the posts coming. Much appreciated!

Great to meet your acquaintance! I think Tenac is the only other track day officionato in the M8, or no one wants to admit it. Lol. It is certainly a crazy beast to have out there. People, not Tenac, have a sense if it’s been on the track, it’s wrecked, so they don’t talk about it

Coming from a racebike I think you get it. Not to brag too much about bike racers, but you and I know if you’re fast on a bike, you’re easily fast in a car because the line is more intuitive for us. If you don’t have any natural intuition for the line on a bike, forget it, you’d just be lollygaggin’ around out there. Here’s the Aprilia I raced and never sold.



It’s in street form here but was quite the machine in 2004-2009 before the RSV4 was borne. I raced the Aprilia 550 Supermoto too but I just couldn’t fly through the air like the motocrossers out there.

Anyways, more later.

I just wonder if I could put it in "Track Mode" Rear wheel drive only and give it a go??

I tried this on a two wheel dyno and it doesn’t work. The car doesn’t like it at all. I have to dyno on an all wheel dyno.

Love the coming build plans. You will definitely want to get something other than a Carbahn OTS tune to take full advantage of those hybrid turbos. Custom tune is the only way to go when getting to the power levels you’ll be at now and you’ll want a tuner who can do several logs and revisions to dial it in right. I’m not sure how susceptible these trans are to any issues at these power levels prior to getting a Pure Drivetrain Solutions treatment. If you really plan to beat on it, I’d be wary of removing too much torque limiting but I’m sure a tuner familiar with this platform can address that if necessary in the tune.

Did the 2 day M school in Thermal last month. Continentals worked really well on the M2, M3, M4 and M5s that we thrashed that weekend. I asked the instructors how these compare to P Zeros and Michelins. These guys all race. They all said the P Zeros and Michelins are faster for a lap or two but the Continentals are a better tire for longer racing stints.
I did not notice much fade while on the big track.
Was wondering what your thoughts are about these tires.
Have enjoyed watching your racing videos.

Hey mate, yes I’d say they are correct. I don’t ‘race’ the M8 so I don’t do 7-11 hot laps in sequence. That will end this car and I don’t expect it’s up to that kind of work. Definitely no endurance racing.

I usually go 1-2 warmup laps, 2 and maybe 3 hot laps, 1 cooldown lap, then off the track. I would do something a little longer on a 4+ km stretchier track.

The Cup 2s are much quicker in the scenario above but they definitely get very greasy when hot and there’s an art and science to control them when that occurs. Sliding around doesn’t bother me when there’s no walls around, but it can slow you down as your being told by others. It’s too bad the camera for the Garmin Catalyst is gimballed. I’d like to see the car actually move sans gimballed or software effect, whatever it’s doing.

On the street, the Continentals are dangerous for the low end torque this power plant delivers and have very little on-demand traction. In 2WD manual mode no traction control, cold tires, forget any hooliganism. The car isn’t controllable. The Cup 2s are much better. In the dry of course. In the wet, the Hankooks are my choice and I’ve run them on the track in an all-day downpours twice now…too much fun. The M8 was shiny wet on those two days. Nothing touched it. The P cars were essentially grounded. Even a 992 with PS4s was grounded. Driver? Idk, they all can’t be turd drivers.
