pshhhh save the money on the clutch too
I have ran two F1 racing stage three kits (sprung six puck) and I have never had a spring break, chatter, or clutch slip or any other issues for that. I always end up pulling a transmission before they wear down and replace the clutch just because its easy to access then. I also ran a third F1 disk with an XTD flywheel and spec pp and that worked out well. The pp is not heavy duty it feels like a stock replacment with a better disk. Its a good streetable set up and my daily has been running it for years.
I did run a F1 TOB that came with the clutch kit once. I didnt have an issue with it but I normally run nissan ones from gspec.
The most power I ever put down on this was a ve with bolt ons and a 75 shot.
so basicly for $300 you have a lightweight flywheel and clutch kit shipped to your door.
