Yeah as you guys mentioned I'm not really planning on doing anything serious or beyond local events, I'm just lookin to get some seat time. I am indeed on street tires, I'm currently on Sumitomo HTR Z5s. When I was figuring out (or trying to at least) the classing I was primarily going off of the car class worksheet posted somewhere because I got somewhat confused when looking everything combined. It was indeed the radiator that made me think that I'd be in Street Prepared, as from what I could tell that would have put me outside of STR. Upon closer inspection of the rulebook though, I see now that I can still run in STR since it is not smaller/lighter than the OEM one. Thanks for the help, probably wouldn't have caught that otherwise.
Hey everyone, Brand new here and I finally think I'm ready to try my hand at this, but I wanna make sure I've got the classing down first. I've got a 1996 M3 Coupe with some minor modifications: Koyorad radiator, Spal electric fan, Hawk HPS 5.0 brake pads, new suspension bushings, and BC Racing coilovers (so springs, dampers, and camber plates). Looking at all the documentation on the website I think this would put the car in BSP, but I just want to double check first. Thanks!
