I have a 2009 WRX and Im looking to put a new clutch in it since ive begun to notice my stock clutch is slipping. The only mods I have done are Cobb Access Port Stage 1 w/ AEM CAI. Ive been told to go with an aftermarket OEM clutch kit and then Ive also been told to do a stage 1 organic upgrade. Im torn on what to do, since I do have an increase in hp and tourque from the cobb stage 1 w/ AEM CAI but then again Im not sure if the gain is enough to justify in getting a stage 1 clutch kit. Any suggestions would be greatly appreciated!! Super indecisive on what to do!!
Yeah thats what I was saying to myself! " why is my clutch slipping!?" I guess when I got the car I was a lil boost happy since I owned a 2.5 RS before, so having a turbo finally was a blast! but I never launched it or anything, just hard charging here and there, but never raced it nor pulled off the line type of driving shit. Oh and one more thing the load feel on the clutch pedal is super heavy and it grabs super high. Im assuming those are indicators for a new clutch is needed??
Grabbing super high can be a sign, but generally when your rpm's rise with little or no change in speed is how to diagnose a slipping clutch....
A good way of knowing is putting it into a higher gear, 3rd or 4th, and floor it from about 2k rpm's and see if it accelerates as it should. If it goes for a little bit, then the rpm's really rise quickly with not much speed gain, slipping clutch.
Yeah its slipping for sure, just matted it in 4th and the rpms rose but speed didnt. So you would go with an OEM replacement clutch for my set up and it will be able to handle it for the long haul, granted I take it easy this time around haha (Cobb AP Stage 1 w/ AEM CAI)
I use that clutch... on an upgraded 04 STi with a 6-speed not a virtually stock WRX with a 5-speed. No, that's way too much clutch for the 5-speed. Stick with stock clutches at that power level. If you burnt it out already, you're probably driving incorrectly. How many miles did you get on it?
