Just some information on this upgrade...IT ROCKS

Kent H and I did the upgrade on my car the other weekend while he was in town. It was a fairly straight forward drop in. RTMs brackets on my 1991 1GA did require a little shave on the area where it goes into the carrier brackets but just slightly.
Had a little issue with some warped rotors but thats resolved at this time.
The brakes are unreal the stopping powers what you would want from a car the pedal feel is bang on and the stopping power is unreal. Went through a proper seating of the pads with the new rotors (in my case they were white box rotors) the stopping power on some of my pulls from tuning runs were impressive. I have all new brakes all 4 corners but once I upgraded to the fords on the front I have to say my confidence in stopping powers way up now. If your boosting more and want to stop faster get these or go one better and do the brembo or willwoods! You will be happy you did
