I have heard good things about the spec stg 1 and 2. A buddy of mine had a h/c/i 308 92 GT, and he had a stage one, and he liked it, until
he took it too the track.. Then it would slip like crazy, and sometimes smoke leaving the line. He switched to a stage 2 and has zero complaints.
Another guy i know with a h/c/i s-trimmed 93 coupe has the stage 2 and he said it grabs well, but he might switch to something else. I would stay
away from the stage 3 though. 2 guys i know, both with Terminator swapped New edge GTs had the stage 3s, one split in half on the dyno, the
other lost a clutch fin launching on the street. So, long story short, the stage 1 should be fine for your needs. haha
