Brembo 06-12 325i (Excl. xDrive) Rr GTR BBK 4 Pist Billet 345x28 2pc Rotor Slotted TY3L - Nickel

This Brembo Rear GTR Big Brake Kit is specifically for the 2006-2012 BMW 325i models, excluding the xDrive variants. It's a comprehensive upgrade designed to significantly improve your braking performance. The kit includes 4-piston billet aluminum calipers, which are lighter and stronger than cast iron, and a pair of 345x28mm two-piece slotted rotors. The slotted design helps to dissipate heat and clear away brake dust and gas, ensuring more consistent stopping power, especially during demanding use.

The calipers themselves are crafted from billet aluminum, a material chosen for its strength-to-weight ratio, which helps reduce unsprung mass for better handling. The 4-piston design offers increased clamping force over stock calipers, translating to shorter stopping distances and improved pedal feel. The two-piece rotor construction allows the rotor ring to expand and contract independently of the hat, which helps prevent thermal stress and warping, leading to longer rotor life and more stable braking. The nickel finish on the caliper provides a durable and attractive look.

This kit is a substantial upgrade for your 325i, offering a noticeable difference in braking performance and feel. It's a well-built system from Brembo, a company known for its high-performance braking components. When installing this kit, ensure you have the necessary tools and refer to the manufacturer's instructions for proper fitment and setup. While this kit is designed as a direct fit for the specified models, it's always a good idea to confirm all clearances before final installation.
