Aero Big Brake Kit with STR Calipers

The StopTech Front Big Brake Kit (BBK) is engineered as the ultimate street braking system, utilizing lightweight components derived from StopTech's racing heritage. This kit features forged, lightweight Stoptech STR calipers, floating slotted AeroRotors, and race-engineered caliper brackets. It also includes stainless steel brake lines for a complete upgrade. To enhance street usability, this BBK incorporates silicone dust boots for extended service intervals and anti-rattle rotor mounting hardware to ensure quieter operation. The kit comes standard with StopTech Street Performance brake pads, suitable for high-performance street driving and occasional track use. The rotor size is 380x35mm with a slotted finish and Trophy Anodized calipers. It is important to note that this kit does not fit stock wheels, as the calipers may interfere with the spokes. Verify fitment with your vehicle, and confirm compatibility, as wheel fitment is the customer's responsibility. This kit is designed for the 2008-2013 BMW 1 Series M and M3, and the 2011-2012 BMW 1M Coupe.
