my 15" wheels are pretty bare and i mistook it as shuddering. it's just severe wheel hop. i guess i'm a tlok newbie, so i will figure these things out. the quad shock brackets will go on soon, i really really need them. no money for new LCA's now.
oh, and by the way, 4.10s don't really feel that fast on my 5spd. i hope the track tells me otherwise. my 60' will probably be the same. if i get an ok launch and floor it, i actually can chirp my tires at the end of 1st gear. i guess they are pretty steep gears, but i don't feel that much power. i need to pick a fight with a gt at the track soon.
