Once you buy Endless Racing 4 Rear Big Brake Kit for BMW 320i, 323i and 325i E90, you will find the included brackets are made for your vehicle, so the kit bolts on without cutting or drilling. Use fresh, high-temperature brake fluid when you bleed the system, tighten every bolt to the correct torque, and check that the new lines have enough slack and stay clear of moving suspension parts. Turn each wheel by hand before driving to confirm the caliper clears the inside of the rim with room to spare.
After you buy Endless Racing 4 Rear Big Brake Kit for BMW 320i, 323i and 325i E90, a careful bed-in procedure gets the best from fresh pads and rotors. Make several medium stops from about 40 mph to 10 mph, then a few harder stops from higher speeds, without holding the car stationary on hot brakes. A slow cool-down drive afterwards lets the pad material settle evenly onto the rotors, which gives you a firm pedal and consistent bite from the very first week.
Before you buy Endless Racing 4 Rear Big Brake Kit for BMW 320i, 323i and 325i E90, think about how you drive. Street-focused compounds give quiet operation, low dust and good cold bite for daily driving, while track compounds hold up to much higher temperatures without fading. If your car sees both commutes and occasional track days, a dual-purpose pad is often the best compromise. Our team can recommend a compound based on how you drive, your tyres and your power level, so you get the most from your purchase when you buy Endless Racing 4 Rear Big Brake Kit for BMW 320i, 323i and 325i E90.
After you buy Endless Racing 4 Rear Big Brake Kit for BMW 320i, 323i and 325i E90, inspect the pads and rotors on a regular schedule and after every track day. Change the brake fluid at least once a year, since moisture lowers its boiling point. Wash the calipers with mild soap and water and avoid acidic wheel cleaners, which can dull the finish over time.
