E34 M5 315mm Front Brake Upgrade for E28 528e/535i/M5 - (NO LONGER AVAILABLE)

Product Details

This package uses the E34 M5's 315mm front rotors and calipers as an upgrade to any E28 5-series, including the M5 and the E24 635CSi and M6. The 315mm rotors are 31mm (1.22") bigger than a standard E28 rotor and still 15mm (.59") larger than a stock M5 rotor. The larger rotors will contribute to shorter stopping distances and the extra mass is better at managing heat, especially under track and fast road conditions. And E34 M5 rotors feature a vented hub for even better brake cooling. The E34 M5 brakes are a straight bolt-on to the stock E28 spindle. Your original brake lines and pad wear sensor fits with the new brakes. Some 16" wheels may fit over the M5 brakes but 17" wheels are better. The only other recommended item is the E32 brake master cylinder which will push more fluid through the system and avoid longer pedal travel. This has long been an underground secret upgrade among E28 enthusiasts but only recently have calipers and caliper brackets been available at very reasonable prices. You no longer have to pick them off a junk car!

The original E28 M5 caliper is a 4-piston design that is becoming harder to source as a fully rebuilt unit. A new caliper from BMW will sell for around $600! Caliper seals are still available to rebuild a useable original caliper. But if the pistons or caliper housing are scored or rusted beyond saving then a full replacement is your only option. And that's what makes this kit such a great upgrade and replacement alternative. It uses OEM parts that are a direct fit to the car and replacement parts are very easy to source down the road. This has long been a common upgrade for E28 owners so this makes a great overhaul kit for cars that have already had the conversion done.

The E34 caliper has a lot more options for pads than any stock E28 caliper. The pad shape is the same as an E36 M3 so there are dozens of options for street, mixed use, and all-out track pads. We've made a few options available in the menu below or you can browse all of our E36 M3 pad options by clicking over to the pad section here.

Notes:
- 16" or larger wheels are required to clear these brakes. Some 16" wheels will not clear depending on their barrel design. Spoke design on any wheel may require the use of a wheel spacer for clearance.
- These are rebuilt calipers so a core charge will apply to each. The core charge is a mandatory selection in the menu below. This charge will be refunded in full when you send back your original calipers with brackets (in the boxes we provide).
- Rebuilt calipers are not coated or painted and they will go through several stages of surface rust. If your calipers will be visible through your wheel, we strongly recommend painting or coating the calipers prior to installation.
- Larger rear rotors from the E34 are also recommended with this kit to avoid too much front brake bias. Using only the front E34 M5 brakes will shift bias towards the front which could lead to easier front wheel lockup during threshold braking. Using the larger E34 rear brakes will restore the brake balance to near stock levels.
 

Price includes $90 core charge on each caliper
