Rich,
What do you think of the 2014 rules changing stock class to street class?
Sway bars on both ends allowed, camber plates allowed, 140+ (200+ for 2015) tires so R-comps are gone, etc... The Rivals are good to go as they are rated 200. Incredible tires btw, amazing. I love them. I can't wait to get them in the bigger sizes though.
I'd like to find a camber plate that *doesn't* raise the stack height. I think there might be one out there now, but I can't recall its manufacturer (I think they made it for the 1M and maybe the M3 too). I know the GC plates I have on my M5 do raise the height by about 1/4" even though GC claimed otherwise.
2014 is going to be an interesting year. I wonder if Hoosier is now going to get into the street tire business.
Oh, and remote reservoir shocks are outlawed in 2015.
