Having lived with both compensators, I have to say that I much prefer the Centra unit. The old one would pop and snap on occasion and I drove the car in manner to protect the compensator rather then just enjoying the drive. I still don't run much below 2,800 rpms in any gear but that's out of habit rather than protection. I believe the dealer in Scottsdale, Az quoted about $1,100 usd for the centra kit and up to six hours of shop time. My car was already disassembled for a frame replaced so I dodged most of the shop time.
