Hello everyone. This is my first post and I hope to benefit from everyone's experience. I have a 2015 WRX limited with 32k miles and purchased it with 29k. I've NEVER dumped the clutch, not sure about the original owner. In a tall gear at torque peak the clutch is slipping. It also shudders off the line a little when the engine is cold. My mods consist of Cobb AP, big sf, TBE, Process West TMIC, and a Delicious Tuning E85 conversion. It's safe to say I've got a little over 400 ft-lbs at the flywheel. I'd like recommendations on a new clutch. I'm not going to do burnouts or dump the clutch. I'd like it to play nice with the transmission. Taking it to the dealer is not an option, I don't mind paying to play. Thanks in advance.
