Product Description

The Goodridge 25054 G-Stop Stainless Steel Brake Line Kit is a performance upgrade for Mazda RX-8 models from 2004-2011. This complete front & rear set replaces the stock rubber hoses with stainless braid over PTFE, improving pedal feel, reducing brake fade, and providing firmer brake response under heavy use. The kit includes all the hardware needed--banjo bolts, adapters, washers, and line locators--for a bolt-on replacement using OEM mounting points.

Because they don't expand like rubber hoses, these braided lines maintain higher brake line integrity under load and temperature. With working pressures over 4,200 PSI and burst ratings above 12,600 PSI, this kit is ideal for spirited driving, autocross, daily driving with frequent braking, or any application where braking performance matters. All hoses are pressure tested and backed by Goodridge's lifetime warranty.
