I guess I misread the October FasTrack, but on p 3 it says "MOTION: To accept the 2009 Solo Rules changes as submitted by the Solo Events Board.(Noble/Introne) PASSED, Unanimous"
Which if I read correctly included moving the Cobalt SS (Turbo and Supercharged), Mazdaspeed3, Audi TT FWD, SRT-4, Caliber SRT-4, Dodge Daytona, Honda Prelude, and many others from DS to GS. I can see several of those cars giving the Cooper S a run for its money in GS.
This was the same FasTrack the removed the RX-8 from the exclusion list in STX.
