Just put on some BBS 2pc 17" rims with Kuhmo All season ECSTASA(sp?) not the best tire for the track by the way, gonna get some summer tires next time, then consider R comps in the future. (Edit, the race pads I put on were Hawk HT10's... and WHOA, they made a difference... Im also a bit of a car noob but I changed them myself in under an hour with a few friends giving me direction and tools).
I have Vogtland springs with Billie sport shocks... an E30 M3 shift kit and the motor is stock except for a chip. Other than that all of the upgrades have been cosmetic.. euro trim, 5k halogens, tint, french fogs, alpine head with Dynaudio components and a JL 10w6, running off of a JL 450/4 and a 500/1.
This was my second track event... and a few instructors thought my M5 handled pretty well (its a 525

) they were surprised that the 525 was so nimble... I was tossing her through the turns, and I was keeping up with my friends C32 AMG... his top speed in the straights was 126, and I was getting up to 120. I definately had him in the corners
