STR-40 332x32mm Front Big Brake Kit

The StopTech STR-40 Front Big Brake Kit (BBK) offers a significant upgrade for your BMW's braking system. This kit includes 332x32mm slotted two-piece rotors paired with StopTech's STR-40 calipers, designed to provide superior stopping power and heat dissipation. The calipers feature an anodized finish with a trophy design for both performance and aesthetics. Engineered for a direct fit, this big brake kit is compatible with the BMW E46 330Ci (2001-2006) and 330i (2001-2005), as well as the BMW Z4 3.0Si (2006-2008). It is important to note that this kit does not fit with stock wheels, and a wheel fitment template should be consulted to ensure proper clearance. This upgrade is ideal for enthusiasts seeking improved performance for track days, spirited driving, or simply a more responsive and confident braking experience. The slotted rotors help to reduce heat buildup and improve wet weather braking performance, while the multi-piston caliper design ensures even pad pressure for consistent stopping.
