Upgrading the WRX brakes with StopTech
Howard starts off our install by removing the rear calipers.
Howard removes the hub nut. We will be changing the wheel bearings because Ian’s car has so many miles on it as a proactive measure.
After removing the rotor, Howard disassembles the parking brake so the hub can be removed.
The knuckle is unbolted from the suspension links and removed from the car.
Howard presses out the hub and old bearing from the knuckle.
The new bearing on the left vs the old quarter million mile hammered part on the right. We ordered the new bearings as OEM replacements from Centric Parts.


  1. You are spoiled with your dry California weather. it looks easy when everything still has factory paint. Trying to do this and the suspension bushings on a similar car here in the northeast would involve torches, penetrating oil, and lots of strong language.

  2. I need a press, lathe and mill… And as DedBull noted, less rust! Sweet upgrade, fingers crossed it will last a long time for you.

  3. Will you be tracking this car? I did 20 track days on an ’04 WRX and found the pad knockback on stock brakes and street tires substantial. A larger diameter rotor will mean larger deflections and more knockback. I was considering going BBK but then the pad knockback plus tracking a car with 60% of the weight in front made me realize it would be cheaper and more fun to do the E36 M3 route. I only miss the WRX on the track when it rains.
