I’ve only been out 2 days at road America, and 2 days at Road Atlanta. No fade. I have revozsport brake ducts off my base m4 that I haven’t installed yet. That’ll be a winter project. Current project is installing a set of OMP WRC carbon seats and harnesses. I hope to do a couple track days in February at COTA and Sebring.

I just had my GTS on track for the first time a few weeks ago. I took 6 seconds off my first session vs the second session by turning mdm off. It's absolutely useless. The car performed really well though. I was having some tire issues, as has been extensively documented in numerous threads. Camber plates are a must. I also have some Recaro 2700G's mounted and OE GTS harnesses. A good seat is a mist have and they were fantastic. No movement at all so you can really focus on driving. I just snagged some AP Essex brakes so 18's are in my near future. 👍
