UUC 330 6 speed LW Flywheel & Segmented Kevlar Clutch

I am considering the UUC flywheel for the 6 speed 330 with Segmented kevlar clutch - does anyone have any experience of this setup?

Thanks

I have the lightweight flywheel...I would stick with the performance organic unless you have a lot of Hp. I have about 345whp and the perf org clutch holds fine.

Thanks . I guess it will need to hold around 420 whp and 370 wtq. (not for my current setup) I will check with UUC as I don't want to go for a less streetable clutch if I have to.

Honestly, my OEM flywheel and clutch was doing fine with 345who/300wtq. At 90k miles it was still good and didn't slip. The flywheel did have some burn marks but nothing major.

For me, I'm not totally in love with the UUC flywheel/performance organic clutch. I find it hard to be consistently smooth on the street and you do get some tranny rattle. It goes away when you change the gearbox oil but eventually come back when the outside temps get hot. Right now, its not that hot outside (maybe 80's), not rattling and I put in Redline MTL back in July.

Great for the track though. Never had an issue with slippage or heat although I don't shift a lot on the track. A little more effort and the engagement is a little more abrupt. I would imagine the segmented kevlar will be more abrupt and require more effort.

I would consider other options as well.
