im still breakin it in so i cant really tell a big difference. But people made it seem like the 8 lb flywheel was so hard to drive with. I drove in heavy traffic with it and no big deal. Revs dont drop that much faster either. So is 500 miles both hwy/stop and go good enough for a breakin period?

 

if you installed everything right and tightened everything down nice and tight then hell yes. i drove mine 1000 before dropping any gears
