that twin turbo in a pretty stock vette CAN cause the other weak links in your vette to stand out...IRS, the M6 or A4 tranny, etc...parts will start breaking on it so you might be in the same position again. I will say I got to see the APS stuff at SEMA & it does look very nice & they have a very good rep so the kit itself would probably be fine...just don't be suprised if parts start breaking around it though with that extra 200-300hp
BTW guys heres the link to that APS kit:
