My clutch is still stock but I have driven cars with a similar LWFW/performance clutch setup. My impressions: Very precise shifts at the track, major PITA driving around town. Probably something I would choose only for a dedicated race car.

A Stage 2 or 2+ is fairly streetable, stage 3 and up gets to be a bit less friendly. Again, it's all about whether or not you actually need the added holding capability.
