Don't forget to look at other brands besides the typical ones. I got a SPEC Stage 3 for $295 shipped from
www.enjukuracing.com. It's a 6-puck disc and has just a little more firmness in the pedal than stock. The torque capacity is just over 300ft/lbs. Not to bad considering it's about $100 less than the ACTs (which don't have close to the torque capacity on the Stage 3). Comes with a new T-out bearing and alignment tool. I put 100miles on mine and took it to the track. Just don't forget to replace the pilot bearing. I did and it makes little noises.
