To drive on the limit, it takes confidence and brakes have the key role in it. GMS big brake kit is designed for serious driving. Why?
GMS big brake kit improves the braking power due to the bigger diameter disc, requiring less pedal force for the same amount of torque applied to the wheels, meaning less heat and better modulation.
Discs are straight grooved, providing extreme de-dusting capabilities and not prone to cracking unlike drilled discs. Discs inner venting vanes are directional, providing supreme heat dissipation. Discs are also fully floating, which means that the they are not directly connected with the disc bells, instead they slide within the bobbin brackets, making them capable of withstanding extreme temperatures without getting warped.
Front and rear disc sizes are carefully sized to transfer brake bias from a very conservative 64/36 to a bit more rearward biased, performance orientated spec, making the car more agile and controllable during the braking.
Discs sizes are 330 x 28mm front and 320 x 22mm rear, which means you can still fit 17'' wheels.
We also didn't forget about the weight. GMS big brake kit offers significant improvement over stock brakes system, yet it weighs mroe than 1.000g less than OEM system. OEM front rotor weighs 6.600g, while GMS BBK front rotor weighs only 6.980g, even though the diameter is increased. However, OEM rear disc weighs 5.750g, while GMS BBK rear rotor, as a result of aluminum center bell, only weighs 5.160g even though the diameter is greatly increased.
Lifespan of OEM rotors, especially for track use is very limited. By having GMS rotors available as a replacement part and cosnidering increased lifspan, the costs of brake overhaul is somewhat split compared to the cost of replacing OEM rotors.
If you are looking for the best brake upgrade system on the market available for your 4C, look no further.
