I have Maximum Motorsports on the rear of my 2K GT. They are great products. I have their HD RLCAs (spherical in one end/urethane in the other) and their 5500 RUCAs (rubber) with new rubber axle bushings as well. I haven't done the fronts yet, but will likely use something with urethane bushings there as well. For stock parts, check Rock Auto...they sometimes have specials that save a few bucks. Happy hunting.
