Is it possible to put paddle shifters on a 2002 WRX manual tranny?
Yes, it's possible.. people have done it in the past. You could use either a KAPS or Modena sequential gearbox. The gearbox itself will run you about $13,000.. plus you will need a six speed transmission from a STI to put it in, the electronics to run it, and of course the paddles themselves. I would guess you could get it all set up and working for around $20,000, assuming you do most of the work yourself.
