Upgrading the WRX brakes with StopTechPosted on October 7, 2018October 9, 2018byMike KojimaHoward presses in the new bearings.The new 328mm x28mm vented Stoptech Aerorotor dwarfs the tiny 266mm x10mm solid stock rotor! The rear rotor is 10.5 lbs so the Stoptech rotor is 3.5 lbs heavier but it is much bigger and has an order of magnitude more thermal capacity.The rear iron caliper is a pound heavier than the forged aluminum and much bigger Stoptech caliper even though it looks a lot smaller.The Stoptech rear pads are taller and have more surface area than the stock pads.Howard reinstalled the knuckle and bolts on the adaptor that allows the use of a radial mount caliper on an ear-mounted knuckle.Next Howard installs the rotor after reassembling the parking brake. The caliper is bolted on next followed by the brake line. The pads are dropped into place last.RelatedPrevious page 1 2 3 4 5 6 7Next pageRelated TopicsStopTech BrakesbrakesStoptech Previous Article Industry NewsDeatschWerks releases 5th Gen Camaro DW400 Pump ModulePosted on October 6, 2018October 6, 2018byMotoIQ StaffView Post Next Article TechEasy AeroPosted on October 9, 2018February 25, 2019byMike KojimaView Post 6 commentsYou 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.Replywell we do make up for it in ridiculous taxes, a nanny state, and higher cost of living.ReplyI need a press, lathe and mill… And as DedBull noted, less rust! Sweet upgrade, fingers crossed it will last a long time for you.Replythanks! I hope it lasts a while too!ReplyWill 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it rains.ReplyNever mentioned if you had to increase wheel size?ReplyLeave a Reply Cancel replyYour email address will not be published.
