Hi all, after some heavy thinking, ive decided to sell my '02 C4S and start with a mk 1 car to build into a track car. i recall reading that the 996 gt3 was based on c4 architecture due to the stronger body. if i buy a c4, can PSM be removed via software deletion (IIRC, PSM is standard on the c4/s both mk 1 and 2?)? i would just drop the torque tube and front drive half shafts, essentially brining me to having rear wheel drive, but my concern is PSM still kicking in even when clicked off if i accidentally tap the brakes...

or should i just shoot to stiffen up a mk 1 996?


Cheers, and enjoy the sunshine!

I believe the the costs associated with trying to convert a C4 into a GT3 would be prohibitive. You would probably be better off just buying a GT3. Hopefully others with experience buiding track cars will chime in and give you some guidance.

Good luck!

sorry, i should clarify. not a TRUE GT3, just an electronic nannyless car, rear wheel drive, aggressive alignment, stripped down club racer. you know, tequipment roll bar, anti roll bars, coil overs, seats, strip the sound insulation, pads, stainless lines. something that serves as a 80% track, 20% street car, air bags and cats in place, but quite frankly not a car youd want to drive for more than 3-4 hours (something you could commute to the track in and back)

I don't think you can buy a MK I GT3 in the US. They weren't sold here, so you'd have to buy it OUS and import it. That would be expensive. A MK II GT3 is probably a better option.
