Brembo 04-10 5-Series (Excl. xDrive/M5) Rr GT BBK 4 Pist Cast 345x28 2pc Rotor Slotted Type1-Yellow

Brembo is a name many people trust when it comes to stopping power, and they're known for making high-performance braking components. This rear GT Big Brake Kit is built for 2004-2010 5-Series models, but be sure to check that your specific car doesn't have xDrive or isn't an M5 model, as those are excluded. This kit is designed to give your car a serious upgrade in braking performance, especially if you're looking to handle more demanding driving conditions or just want a more responsive feel at the pedal.

At the heart of this kit are the 4-piston calipers, which offer more clamping force than a typical 2-piston setup. These calipers work with 345x28mm two-piece rotors that are slotted. The slots on the rotor surface help to vent gases and dust away from the pad surface, which can lead to more consistent braking performance, especially during repeated hard stops. The calipers themselves are cast, and the rotors are a two-piece design, which helps manage heat better than a single-piece rotor. This kit is a substantial upgrade over stock, intended for drivers who want a noticeable improvement in their car's ability to slow down reliably.

When you're installing a big brake kit like this, it's a good idea to have a full brake fluid flush and replacement with a high-performance fluid. Also, consider that you might need to check your wheel clearance to ensure the larger calipers and rotors will fit inside your current wheels. This kit is a significant investment in your vehicle's safety and performance, and it's designed to provide a noticeable difference in how your car stops.
