My 04 STI clutch is now slippin occaisonally and I was wondering what would be a good replacement flywheel and clutch kit. I had been looking into the Fidanza flywheels but was advised on the low weight of 9 lbs would be a problem. I know that the stock one weighs around 22-23 lbs and was lookin to lighten it up somewhere around 10 lbs. I just can find any decent websites with info on 04 STI clutches. Anybody got any suggestions??? Now for the clutch kit I was looking into a kit from either Exedy or Spec. I know that I am not gonna ever go over 400hp. I'm looking for something daily drivable but also giving me that edge when I need it. I know i wanna upgrade from the stock clutch but cant decide on which one. What are the differences between stage 1,2,3 and different puck designs? What kinda material should I be lookin for? Another thing to factor in is my budget, Im lookin around $400-800 for both clutch kit & flywheel. Anybody have any suggestions that that used on their STI or have heard from anybody about any great products plz let me know. thanks
i have an excedy oem clutch in my wrx (not puching enough power for something stronger) along w/ an excedy flywheel. the flywheel is around 12lbs. and i have not had a CEL thrown at all.
This is a great read and I suggest you give it a look through. It's unabombers (nasioc mod) faq on clutches and flywheels. Clutch & Flywheel FAQ
Thanks for the link, what kinda of ACT clutch, is it the SB4-HDSS and what are they charging you for labor?
