I've got a Spec FW and pressure plate with an ACT street disc. I bought the FW and clutch kit used on Ebay and didn't want to run the old clutch. I never drove the car with the stock setup, so I don't know how it compares other than sitting in Legacytuners car and noticing a HUGE difference in pedal pressure. Also, in alot of slow stop-and-go driving it gets tiresome keeping the clutch depressed. Overall performance, I'm very pleased. I'm sure you won't regret it if you buy 'em. :D

I run the Spec stage 1 clutch kit with the ACT streetlite FW and I like it for the most part. he only complaint I have is that it shudders a bit but this is because the syage 1 kit comes with the old Exedy WRX disc that is known to have shudder problems. I plan to go to a 6 puck ceramic in the future.

I am using a Kennedy 6 puck carbotic disk ($97) and a 02 RS pressure plate. I will break gears before it slips. No shudder and easy to drive. It does engage hard though if you are not careful.

Exedy Stg.1 + pressure plate + LWflywheel and I dig it. A heavier flywheel would have been nice for launching, but I like quick blips to change gears.

I had their SPEC Stage 2 (Kevlar) Clutch and their lightweight flywheel in my 2.5RS.

I hated the clutch (overheated too easily and once it did it was useless until it cooled back down again) and have since replaced it with an Exedy Stage I (organic) clutch kit instead.

I absolutely love the flywheel. From what I've heard, it is identical to a Fidanza flywheel (which makes sense as they are both right at 9 lbs or so), except SPEC uses their own ring gear and balances them themselves. Since it is aluminum, you don't resurface it during clutch swaps, but instead buy a replacement friction surface from Fidanza and swap that part out (which is exactly what I did when I installed the Exedy clutch kit).
