REDSPEC Group N discs undergo a specific heat treatment and a particular machining process, ensuring powerful and enduring braking.
Associated with competition pads, they will allow later braking while preserving the temperature rise.
You will thus gain precious seconds in the race and during your circuit days!

Can be mounted in place of your original discs (identical dimensions).
Please carefully check the compatibility of these discs with your vehicle.
These discs comply with ISO 9001, ISO / TS 16949 and TÜV standards.

For optimal performance, be sure to follow the break-in phase described below:
1. Cap the inlet of the coolers 3/4
2. Use lapped (hard) pads
3. Gradually heat the discs for the first 15 kilometers.
4. Use the vehicle normally without being violent on the brakes.
5. End with 5 or 6 hard braking.
6. If thermal paints are used (reference CP26491) only the green paint (430 ° C) should have whitened and the orange should barely begin (560 ° C).

In order to operate at the best efficiency and last as long as possible, the temperatures of the discs must be correct and balanced.
In general, the discs in a vehicle should all operate at the same temperatures.
The maximum disc temperature must be matched with the quality of the pads used.
The faces of the disc should not exceed the maximum recommended temperatures for each type of insert.
