First track weekend with my M2C coming up later this month, and after seeing how unstable the rear end can get with high speed cornering, I would like to see if there's a way to "tune" that out with toe or other alignment tweaks.

I don't plan on camber plates, because I will be going with MCS 1-ways later this year or next.

Hey spooni - I ran the oem alignment at COTA a couple of weekends ago and really was pleasantly surprised with the stability of the car through the higher speed corners. The rear can get a little unstable but found that it communicated well when it was happening and then was very easy to bring back if needed. This was with both the oem spec MP4S and Pirelli DH slicks. Definitely wasn't snappy or twitchy, anything like that. Might be able to get a bit of improvement but to me it wouldn't be worth the hassle, time, $$. Really was impressed with the car in stock trim, can only imagine how good it is going to be with a few goodies on it.

Thank you!

Maybe it just depends on the track, but I saw someone post a video yesterday of his car breaking at high speed on a sketchy part of buttonwillow. I'm not a super advanced driver, so stuff like that still makes me a bit nervous.

i dont find the car unstable in the rear end in high speed cornering at all. the OEM set up is really fast.

The only thing you can do is play around with tire pressures..

your instability maybe due to incorrect tire pressures/cornering speed/braking in corners etc... suggest speaking to an experienced track driver for advice.

i was able to rip out really fast times out of the box from the show room in stock set up. Nothing wrong with the car

I think you're referencing the video posted on the M2 FB group. If you watch the video closely, the driver upshifts as he has the steering wheel turned slightly right into an uphill turn and the rear stepped out as he got back on the gas. You typcially want to have braking or shifting inputs done in a straight line before a turn in order to keep the car balanced. The shift most likely shifted the weigh forward and then applying power while the rear was unloaded and already turning right just made the rear let go a bit.

Thanks, that def makes more sense.

High speed stability is really good with OEM alignment as far as the rear/front toe in are still in the tolerance.
