I don't want to beat a dead horse, I've done some searching dating back to 2007, also curious about flywheels with these two clutch kits. Looking to hear from people who've actually had these clutches. As of now my car only makes 455rwhp/479tq, but it seems I have some noise in my T56 which likely is a TOB, retainer sleeve or both. At some point in time I'll likely put a whipple on. But are these clutches fine with my power level and street use? Car see's zero drag strips. I'm starting to make a list of things to replace while the tranny is out, and man I have about 2300-2500 just in parts! Of course the Lethal discount will help some! Also I was looking at the fidanza aluminum flywheel, but there seems to be alot of debate over steel and aluminum, but this is a street only car. Thanks alot guys!
