Upgrading the WRX brakes with StopTechPosted on October 7, 2018October 9, 2018byMike KojimaThe Stoptech pad is taller and longer for more swept area.The front brakes mounting pad was pretty rusty so Howard buffed it all off.Howard bolts the radial mount adaptor to the freshly rebuilt upright.The Aerorotor slides on next.Next, the ST40 caliper is torqued down to spec.The stock rubber brake lines are replaced with Stoptechs DOT-approved braided steel parts. Braided steel swells less than rubber under pressure and thus improves brake feel. Braided steel lines have a hard time passing the DOT whip test and Stoptech lines have molded-in reinforcements that prevent the steel braid from bending causing fatigue and failure during the test.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it rains.ReplyNever mentioned if you had to increase wheel size?ReplyLeave a Reply Cancel replyYour email address will not be published.
