I was going to get a good aftermarket clutch for my car. however, I still have the t5. Now I do plan on getting a older tko or a tko500/600 when the t5 does go. My thoughts were if I plan on getting a high perf. clutch and then need to buy another one as the spline count is diff. why not install a weak link into the system and save a few $$$. now on the bottle I should be close to double the trq rating of a t5 (assuming I have 300ft lbs on motor the 175 shot will add about what 200ft lbs = 500ftlbs) so it is a matter of time. So I got a stock replacement (rememberd I had a warranty on a veleo(sp?) so I got a brand new clutch, PP,ToB, and input bearing for free) to try and keep the t5 together for a year or so. I would rather blow a clutch (other replacements would be free as well, thank you autostupid) than the trans.
Just one idea I had not seen, esp. if you plan on upgrading when the t5 does go.
