Yes, the OG M2 also has more aggressive cooling in Sport and Sport + (at least for the Engine coolant), there are no fans or valves for the oil I don't think, just the front mounted oil cooler. Oil temps are not the problem for the N55, the IATs are. Here advantage to the M2C with the Air to Water intercooler.

Mine is stock though, so no issues here. Just a bit less power.

And I agree on the runout room at La Rouge. With the M2 just a little brake apply before entering to transfer weight seems to do the trick, then I found I can be back on the power right away, and then as soon as I see sky I steer left. But in general I also noticed plenty of room to try to go faster next time. I think it's plenty of room *as long as the rear end doesn't slide

Duplicate in wrong thread. Please delete.

Is the marking indicating I am using the full contact patch or should I raise or lower pressure ? I also saw a little hotter temps in the inside vs the outside. Running -2.5 camber and 0.04 toe in each side.

[5.M0NSTER]

Almost there I think. What pressures are you running when hot? You cold probably drop a PSI or 2. I try to destroy the tip of the triangle.

Also hotter temps on the inside is strange. Did you still have Traction control or any MDM mode on? That could explain it as brake act on the inside to add rotration, or to limit the slip on throttle. This would add heat to the inside tire.

Do you not run in traction mode?

[PLF69]

Yep ran all my sessions in MDM (traction). I also have the effect on the rear tires, hotter inside but I thought it was caused by .30 total toe in the rear.

Not for the last few years. I typically run in full system off, ABS only. The only exception is the Nordschleife, because I'm still a bit scared of it.

To get there do you just hold down the DSC off button for longer?

Yes

Yes, about 7s or so. And you can get there from any MDM mode you might already be in. Same procedure.

[243Racing]

I’ll try it next time out. I spun in traction mode last time...

That looks like good wear to me, though it really depends how hard you are pushing the car. On my RE-71's the almost the whole triangle gets destroyed pretty quickly, but I only run -2.5 of camber.

Turn off DSC as soon as you can, the cars are naturally very stable and progressive once you exceed the limits. People who run with DSC all the time develop bad habits (i.e. mashing the throttle on exit). Turn of DSC, drive a couple of seconds a lap slower and get a feel for how the car naturally behaves. Then you can work back up to where you were with MDM, focus on being smooth with steering inputs and braking. I am a lot faster and enjoy it a lot more with DSC off, the software generally doesn't really like trail braking and fights if you try and rotate the car too quickly in my experience. MDM also absolutely cooks your brakes as it's always making little braking adjustments which you don't really notice to try and keep the car more 'stable'.

Here are mine. Too much pressure?

Could be, how does the middle of the tire look? What are the hot temps when you come off track? Every tire is different, I have never run Toyos myself. Research what hot temps people are recommending.

RE-71's which are similar seem to be most comfortable around 36/37 PSI hot in my experience, anymore and the center gets annihilated even quicker than it normally does. In my M3 that meant starting around 27/28PSI after a session or two, I expect the M2C to be similar given the cars weight.

[243Racing]

I don’t have a pyrometer, so I’ve just been trying to keep them in the suggested hot PSI range.

I’m also finally getting camber plates and a track alignment. Would love any suggestions you guys have.

I cant say I 100% agree with this but maybe its the delta between Euro MDM and US MDM.

In Euro MDM you can drift the car quite a bit. Trail braking into a corner is also not an issue. If you are too aggressive though it will kick you into normal traction which is very restrictive.

This was me this week at a wet Assen in Euro MDM.

I use the TC to teach in a proactive maner. If you see the light flashing the whole time your overdoing it. Adapt your speed/throttle to minimize the interventions.

This way you still retain the safety net without falling into bad habbits.

[243Racing]

Good point. I have GTS MDM - perhaps why it doesn’t seem as intrusive as regular MDM

[PLF69]

I was running Thor Clubsport (GTS) MDM + Diff (GTS)

The wet is a different story - I also run MDM in the wet mainly for TC as I'm not in a position to write off $60k of car

Even when the traction light isn't blinking, the DSC is intervening. There is a very informative thread on here (just spent 10 mins looking, cant seem to find it) where a poster pulled data with MDM on. It's is on the brakes a lot to prevent rotation, particularly in the rear.

Not saying MDM is necessarily bad, its a nice tool to make you feel safe on track. But in my experience if you care about going as fast as possible on a dry track it's going to hold you back once you get to a certain level. My main gripe is with DSC off is it turns off rev matching on a MT which I really like to have on track.

I have the same issue vis a vis trashing the car.

I think im fairly fast (hey I caught up to that TTRS with its Quattro and at least stage 1 tune in the wet in a stock M2C on cheapo semi slicks). I will try traction off next dry trackday though. I have done enough trackdays and drift days with the M2 now that I feel confident.

I have the DCT so revmatchin aint a concern I love how its practically like a sequential GB!

[243Racing]

Because...racecar.

[5.M0NSTER]

Was this in the process of removing the mufflers?

Because otherwise I don't get the reference to Talladega Nights
