Great thread guys. I feel like I"ve almost "got it."
I have an 05 OBXT and the original clutch started slipping this morning, as I accellerated through a yellow light in third gear. RPM's started to climb quickly, and no increase inspeed, accompanied by slight scraping sound as I let off the gas.
My mods are: AP (OTS Stage II map), Catted CNT downpipe, Grimmspeed up-pipe, and a custom single 3" exhaust that is getting installed as we speak by Stebro Exhaust in Ottawa, Ontario)
I understand that I have the dual-mass FW setup, which is more expensive to replace, can't be resurfaced etc...
So far, I understand the I can transition to 07-09 LGT/06+ WRX Singlemass Flywheel and clutch combination (OEM or aftermarket) without a problem. Does the timeframe in which my car was made 04 vs 05 have any bearing on whether or not the new clutch (07-09 LGT) will actually fit?
I'm thinking a mild upgrade over the OEM clutch is preferred, since I'm looking at stage II as my mod-ceiling right now.
Last question is the TSK kit. Do I need it? My car has 155,000 kms, but I don't want to order the kit if I don't need it, nor need the kit and not have it.
Thanks again for the great tech advice.
