The \u003cstrong\u003eRadium Engineering Master Cylinder Brace\u003c\/strong\u003e counters that flex with a 6061 billet aluminum brace that mounts to pre-existing threaded holes in the engine bay, no drilling, no permanent modification. Because the master cylinder flexes in an arc rather than straight back, a specially designed CNC machined foot contacts the cylinder to counteract that arc movement. Firmer, more consistent pedal in under 30 minutes.\u003c\/p\u003e\n\u003ch3\u003eWhat You'll Feel\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eA firmer, more positive brake pedal with less dead travel before real bite\u003c\/li\u003e\n\u003cli\u003eConsistent pedal feel deep into a track session, when you lean on the brakes hardest\u003c\/li\u003e\n\u003cli\u003eMore precise threshold braking and easier heel-toe work from a predictable pedal\u003c\/li\u003e\n\u003cli\u003eA quick, reversible install that leaves the car exactly as Subaru built it underneath\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCNC machined 6061 billet aluminum construction, anodized and laser engraved\u003c\/li\u003e\n\u003cli\u003ePurpose-shaped machined foot contacts the master cylinder to counteract its arcuate flex path\u003c\/li\u003e\n\u003cli\u003ePreload adjusts via the anodized aluminum green bolt, locked with a stainless steel jam nut\u003c\/li\u003e\n\u003cli\u003eMounts to pre-existing threaded holes; no drilling or permanent vehicle modification\u003c\/li\u003e\n\u003cli\u003eInstallation takes less than 30 minutes with basic hand tools\u003c\/li\u003e\n\u003cli\u003eAlso provides the mounting location for the Radium Air\/Oil Separator Kit 20-0258 (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Details\u003c\/h3\u003e\n\u003cp\u003eFirewall flex is a geometry problem. When you brake hard, hydraulic reaction force pushes the master cylinder away from the pedal, and because the cylinder hangs off the booster, it does not move straight back; it swings through a slight arc. A flat brace face would contact it poorly through that motion, which is why Radium machined the contact foot to meet the cylinder correctly as it tries to move. Setting it up is simple: bolt the brace to the existing threaded bosses, run the green preload bolt in until the foot just contacts the master cylinder, and lock the jam nut. The result is that pedal effort translates into line pressure instead of sheet metal deflection. Fitment is left hand drive only, and if you are planning Radium's WRX air\/oil separator kit, this brace is the mounting point it is designed around, which makes the pair a natural install day combo.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x CNC machined billet master cylinder brace, anodized and laser engraved\u003c\/li\u003e\n\u003cli\u003e1x Anodized aluminum preload bolt with stainless steel jam nut\u003c\/li\u003e\n\u003cli\u003eMounting hardware for pre-existing threaded holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2015-2021 Subaru WRX (left hand drive only)\u003c\/li\u003e\n\u003cli\u003e2015-2021 Subaru WRX STI (left hand drive only)\u003c\/li\u003e\n\u003cli\u003e2014-2018 Subaru Forester XT (left hand drive only)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672690491459,"sku":"20-0255","price":94.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0255-12018499649606_6e3c12cf-a260-4021-a8d9-d9d27437d04e.jpg?v=1786717065","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-master-cylinder-brace-15-19-subaru-wrx-sti-14-18-fxt-20-0255","provider":"Tuned by Shawn","version":"1.0","type":"link"}
