Product Description

VTT F8X Ultimate Lightweight Front Brake Kit

F87 M2 / F80 M3 / F82–F83 M4

Looking to make your F8X faster in the 1/4-mile or 1/2-mile?

Want to run 17″ front wheels?

Want to drop up to ~40 lbs of unsprung weight off the nose of your M2C/M3/M4 — without breaking the bank?

The VTT F8X Ultimate Lightweight Front Brake Kit is engineered for straight-line performance while maintaining real-world drivability. This system allows you to run the wheel/tire combination required to lower ETs while significantly reducing unsprung and rotational mass compared to the factory front brake setup.

Less weight.
More clearance.
Improved weight transfer.
Faster passes.

Bedding Procedure – CRITICAL

Brake pads must be properly bedded to achieve full braking performance.

Failure to bed pads correctly may result in:

• 30–50% braking effectiveness

• Pad glazing

If glazing occurs:

• Remove rotors

• Sand pads

• Re-bed properly

Your kit includes a bedding instruction card. Follow it exactly.
