Спецификации

8611S Forged 6-Piston Caliper with Race-Spec Castellated Pistons

Engineered for maximum thermal performance, the 8611S is the definitive upgrade for drivers who push their vehicles to the limit. This lightweight six-piston caliper is forged from high-strength aluminum and features a competition-proven design to deliver uncompromising stopping power on both the track and the street.

The 8611S is equipped with race-spec castellated pistons. This advanced design minimizes contact with the brake pad, drastically reducing heat transfer into the brake fluid and providing incredible resistance to brake fade. Paired with a progressive piston layout for linear control and ultra-high-temperature seals, the 8611S ensures a firm, confident pedal and consistently powerful braking under the most extreme conditions.

Frequently Asked Questions

What are "castellated pistons" and why are they better?
Castellated (or "star-type") pistons have grooved cutouts on their contact surface. This design significantly reduces the surface area touching the brake pad's backplate, which drastically lowers heat transfer from the hot pad to the caliper and brake fluid. This is a race-proven technology that provides superior resistance to brake fade during intense, repeated use.
This caliper has no dust boots. Is that okay for street use?
The 8611S is a track-focused caliper. The absence of dust boots allows for ultra-high-temperature seals that can withstand extreme heat without melting. While this maximizes track performance, it does mean the caliper pistons require more frequent inspection and cleaning to prevent debris buildup, especially if driven regularly on the street.
What's included in a complete 8611S brake kit?
A complete front axle upgrade, including: 2 × 8611S Calipers, 2 × Two-Piece Brake Rotors, 1 × Set of Brake Pads, 2 × Caliper Brackets, and 2 × Stainless Braided Brake Hoses.

  3. All products are inspected before shipping. Inspect upon delivery and report quality issues within 24 hours.

2. Initial Break‑In Procedure

  1. In a safe area, brake from 60 km/h to 10 km/h with moderate pressure—repeat 10 times.
  2. Drive 500–1,000 km with light to moderate usage before full braking performance. Avoid aggressive stops.
  3. Our high‑carbon steel discs have grooved, color‑treated surfaces to help quick bedding and resist corrosion.

3. Product Warranty

  • Calipers: 1‑year warranty on defects. Lifetime maintenance available (parts charged).
  • Discs & Hoses: 90‑day warranty for defects. Expected lifespan: 40,000–60,000 km.
  • Brake Pads: 90‑day coverage. Typical lifespan: 20,000–40,000 km.
  • Custom Hats/Brackets: Fit guaranteed; no warranty post-installation.

4. Usage & Maintenance

  1. Do not wash immediately after hard braking to prevent rotor warpage.
  2. Allow extra stopping distance when driving in wet conditions.
  3. If you experience unusual noise or vibration, consult your installer immediately.

Recommended service intervals:

  • Replace rotors when wear exceeds 3 mm.
  • Front pads: every 30,000 km.
  • Rear pads: every 50,000–60,000 km.
  • Brake fluid: every 40,000 km or every 2 years.
