Rear Big Brake Kit 304x28mm, Street Caliper, Fixing discs - Volkswagen GOLF 4 1.8T
This Big Brake Kit for Volkswagen Golf 4 1.8T shortens the braking distance by the strong braking force. This kit is equipped with "Street" calipers (which is extra protected from dust by means of the dust covers) and "Fixing" brake discs with dimensions 304x28mm
Brakepads: The kit comes with "Sport" pads (for street use). For track use we recommend the "Race" pads, which are more resistant to heat.
Calipers: The performance calipers are manufactured from the highest quality solid aluminum. Despite of its lightweight construction, it provides extremely increased braking performance. In addition, the brake calipers are equipped with heavy-duty aluminum pistons combined with heat resistant seals.
Brake discs: The rotors features a two-piece design with a brake disc and a "hat". You can choose from two types of discs; drilled or grooved. Both types help to dissipate heat under the most extreme braking conditions.

- D2 2 Piston REAR Brake Kit has 304 X 28mm brake rotor and is suitable for 16" wheels or above.
- All discs are designed by 2-piece disc and the materials of the bells are made by aluminum.
- The brake systems that we produce, the bell housing of disc use aluminum materials(2 pcs). The rear brake system with drum disc use aluminum materials; therefore, the handbrake is only suitable for parking not drifting in high speed driving.For aftermarket multi-pistons upgraded brake system, you could set up the oil hydraulic handbrake which we manufacture for drifting or special purposes.
SHOULD I CHOOSE DRILLED OR SLOTTED DISCS?
Below we explain the difference between drilled and slotted discs.
Slotted rotors offer improved bite (initial onset of braking) and slightly higher friction level than smooth rotors. Slots prevent reduction in friction due to pad outgassing or brake dust trapped between pads and rotors. Pad coefficient of friction is maintained over the lifetime of the pads, since slots shave away glaze formation and expose fresh pad surface each time brakes are applied. Slotted rotors are by far the number one choice for cars used in competition or open track events. Disadvantages include slightly reduced pad life, some low frequency rumble and pedal flutter when braking hard from high speeds.
Drilled rotors offer slightly more bite and friction than slotted rotors. As with slotted rotors, pad coefficient of friction remains consistent over their lifetime. Wet bite is improved over plain and slotted rotors, so these may be the best choice for areas with heavy rainfall. Weight is reduced by about 0.2 pounds per rotor, depending on size and drill pattern. Disadvantages include possible uneven rotor wear, typically concentric groove formation, although this is mostly an aesthetic concern. A major disadvantage is accelerated formation and spreading of cracks under racing conditions. For this reason, drilled rotors should be avoided for track cars, unless required by the rules. A common piece of misinformation is that they have lower performance than smooth rotors, due to reduced surface area and are for looks only. This is false.
WHAT ARE THE DIFFERENCES BETWEEN THE TYPES OF PADS?
Pads are available in two variants:
- Sport Pads (supplied by default): suitable for street use, good response when cold (steady friction coefficient of 0.46 to 0.53 up to 600 ° C).
- Race Pads: Carbon /Ceramic with excellent temperature resistance, less bite when cold (steady friction coefficient of 200 ° C to 900 ° C)
