When I owned it I wasn't exactly gentle. A lots of miles were spent on mountain roads chasing fahr_side's built WRX.
Though the car was never tracked, I burned through about 60l of meth, two sets of RE-11As, two sets of brake rotors, 4 sets of Project Mu high-temp pads and ripped 3 sets of strengthened front lower control arm bushings. Launching uphill WOT with 4 passengers and a load of camping or windsurfing gear was a regular occurrence. A lot of people broke their tranny's due to the slow and soft OEM shift settings. I bought a broken one and re-built it as a spare, but never needed it. I later sold it to someone who DID break their transmission.
My STG2 STi just can't compare, nice as it is.
