what do you guys go with in the GXPs? my friend has an exedy hyper twin in his GTO that has probably 60k miles on it after he bought it used and it still works great. its seen its share of track time too. one of my vette friends was saying i should check out the RPS street twin and then i see that monster has recently made a street twin disk. I had an exedy hyper single in my cobalt and i actually liked it a fair amount.
