When considering a brake rotor upgrade, it's important to factor in their specific use. On the road, a solid rotor is a simple, yet cheap and effective?solution that is perfectly capable of handling dailydriver requirements. When you start taking your BMW to the track, things become a little more complicated. Extended periods of aggressive driving causes the amount of heat in the rotors to build up, and as the temperature of the rotors increase, the metal begins to expand. With solid rotors, this can lead to numerous issues such as warping of the rotors,?unexpected cracking along the inner "ring" or friction surfaces, and increased brake fade.
This is where?TwoPiece?Floating rotors start to shine. TwoPiece rotors were designed specifically for highperformance applications?and are significantly more resistant to the effects of heat and friction, lessening the negative effects typically seen with standard rotors. The separation of the friction disk and the rotor hat allows for the rotor ring to expand and helps prevent?heat from traveling into other sensitive braking components that could be damaged from prolonged exposure to harsh conditions.
Needless to say, the engineers at Turner Motorsport weren't a fan of track days being cut short due to braking issues, so they decided to create our very own performanceoriented TrackSport Rotors!
These TrackSport rotors feature a semifloating twopiece design and?slotted grooves to allow smooth, consistent braking force and easy expulsion of gases and dust created by the brake pads and rotors under heavy braking. This means that no matter the conditions, you can expect the braking feel to remain consistent, even throughout long periods of abuse.
Additionally, thanks to these rotor's inherent twopiece design and the included Aluminum rotor hats, these?remove almost 20% of the rotational mass versus stock rotors.
