This kit utilizes Wilwood 4 piston forged aluminum calipers. Kit includes 22mm vented rotors, wheels bearings, braided stainless steel brake hoses, calipers and pads. These brakes fit under most 13" alloy wheels. These calipers use a single hydraulic line, so we suggest an E21 320i/323i master cylinder for ease of fitment. These brakes are intended for racing use and should be paired with a rear brake upgrade and bias valve to be effective and safe. This kit ONLY fits Tii struts.
*Note: The calipers in this kit are single line type, so we recommend using an E21 320i/323i master cylinder for ease of fitment. Click options and the 'order'.
**Note 2: The optional 2-piece LIGHT-WEIGHT Rotors are 8lbs each (the standard rotors are 12lbs. each), this means that overall you'll be shedding 8lbs. of rotational weight. This is a very good idea for auto-crossers and hill-climbers (check rules for class-legality).
***Note 3: The E21 big bearing hubs are becoming difficult to keep in stock. Therefor we have priced the kit accordingly and made the hubs an option. You can source your own hubs they are from '77-09/79 E21 320i's.
Feel free to call us if you have any questions (What brake pad to suit my application? Etc.) Kits take around 1 week turn around.
