I have an '07 GT/CS with 55k for miles. My clutch is beginning to feel strange after stuck in traffic (3 hours to go 4 miles). It is bucking a little and I get so shaking in 1st gear. So I am thinking of replacing it. It is my daily driver summer & winter. I have 3.55 gears. What should I look for in a new clutch? What brands etc. The only mod is a CAI and I like to push it hard at times but have only had it down a drag strip 3 times (same weekend as my traffic jam). Any help on this would be greatly appreciated.
