i have had my 06 gt for 5-6 months now.the only performance mod so far is a set of flowmasters.i had it at the track recently on track day and was eaten up by the vettes.i want to upgrade the suspension i have eibach sportline springs and anti roll kit.was wondering what you guys have used and liked.maybe poly bushings,or tubular a-arms, tokico adjusters are looking pretty enticing.i am more interested in the twistys than in straight line.i am new to the forum and any input would be greatly appreciated.
