NEW Brembo Racing system for the Nissan GT-R (R35)

New Brembo Racing system for the CBRD Speed Factory Nissan GT-R (R35).

This is a direct replacement for the front Brembo O.E. (Original Equipment) system which is already an extremely capable system, but this system is meant for environments with heavy brake demand.

The brake system is comprised of a lightweight Brembo Racing XB105 4-piston billet caliper, 25mm pad vs. 18.5mm (increased thermal resistance), and 2-piece, 380×34 type 3 discs that fit under the *OE wheels.

Brembo Racing XB105 calipers have a very low mass and overall weight while improving braking performance (the slimmer profile is optimal for wheel fitment). 4-piston billet caliper, and removable stiffening bridge for fast pad changes (25mm pad vs. 18.5mm which increases thermal resistance).

The thicker 25mm pad vs. 18.5mm OE pad increases thermal resistance (thermal barrrier) and also helps with overall pad life.

Brembo Brake Discs: Face Types

HOW DISC FACE TYPES (SLOT / GROOVE TYPES) AFFECT BRAKE PERFORMANCE:

Brake discs are one of the major brake tuning options which a professional race team has at their disposal at any typical race weekend. There are many subtle changes that can be made to a brake disc casting or configuration which can drastically influence braking characteristics. A brake disc’s face type (slot / groove pattern) is one of those changes, and can influence many braking characteristics.

Some of them are:

  • Initial response (bite)
  • Control and modulation
  • Release
  • Pad wear
  • Disc wear

There are also many variables which are considered when engineering a brake disc face type. Changing some of these variables can drastically influence the overall performance of the brake disc. Some (of the many) variables which are taken into consideration for brake disc slot design are:

  • Slot depth
  • Slot angle
  • Length of slot
  • Number of slots

Brembo and Brembo Racing primarily offer 4 different brake disc face patterns based on the application, intended use, driver preference, and other technical requirements of the application or chassis.

Drilled: drilled brake discs are suitable for a wide range of applications, operating temperatures and driving environments (especially wet weather).

  • Benefit: offers the highest initial response of all the available disc face types while continuously refreshing the braking surface and being also typically a bit lighter.
  • Drawback: Drilled discs are generally more prone to heat checking and thermal cracking if used consistently at extremely high temperatures. This however, really depends on the track, driver, and chassis setup.

Type I: Brembo “8 straight – slot” face type with an emphasis on stable brake feel and improve resilience against thermal cracking.

  • Benefit: stable braking feel at all temperatures, low disc wear, and continuously refreshing the braking surface for optimum performance.
  • Drawback: The Type 1 standard disc face has the lowest “initial response” or “bite” compared to Brembo Drilled, Type III or Type V discs.

Type III (aggressive face type): motorsport developed face type with an emphasis on high initial response while maintaining a smooth pedal release.

  • Benefit: highest overall braking confidence, control, and allows driver to spend less time on the brake pedal. When chasing the fastest lap time, less time on the brake pedal typically leads to a quicker lap time.
  • Drawback: Any disc with an aggressive face type like the Type III will have a higher chance to mechanically abrade the pad and disc surface leading to quicker or uneven pad wear. However, this really depends on variables such as car setup or track layout.

Type V (Endurance face type): motorsport developed face type with marginally less initial response compared to the type III face type. The Brembo Racing type V face type was also designed to have lower pad and disc wear for certain long distance endurance races (mostly 10, 12 and 24 hour races).

  • Benefit: braking modulation and control similar to Type III, while offering lower overall pad and disc wear on the track.
  • Drawback: While the most well balanced of all Brembo face types, Type V discs generally do not have as high of an initial response compared to the Type III.
