I installed my ACS foot pedals today. Got them for $70 (incl shipping) via eBay, compared with $170 at the dealer (and that dealer price didn't include installation!!

)
What an easy, but good "bang for the buck" mod! I used the article posted here (thanks, JVZ104). I might add that the Allen wrench size was 2.5 mm, and the nuts are 6 mm. It would be best if you have a very small open end 6 mm wrench to hold those nuts in place while tightening the bolts, compared with the socket wrench I had, which had a hard time getting those last 2 bolts on the right side of the accelerator pedal.
This is not something I would have done without xoutpost.com!
