Hard-core CEG'er
FYI: Kevlar clutches are hugely popular in the Probe, 626 and MX6 crowd. Boosted KLs (Mazda 2.5L) with ~300whp/wtq run just fine on these. When I upgrade my csvt clutch, which feels like a cheap dyno-wtf $50 clutch from Autozoe, I'll definitely use Kevlar.
The reason why people shun away from the SPEC Stage 2 Kevlar clutch is because kevlar can glaze. Most people skip the stage 2 all together and jump from a stage 1 to a stage 3.
