8-Piston Power for Factory Wheels: The SL8 Direct-Fit Caliper

Get a massive brake upgrade without the expense of new wheels. The SL8 brings 8-piston stopping power to your factory setup. We engineered this narrow-body caliper to be a direct, bolt-on fit for over 90% of OEM 19" to 21" wheels, with no spacers required.

The forged aluminum body is incredibly rigid, delivering a firm, confident pedal feel that eliminates the mushiness of stock brakes. The 8-piston design applies pressure more evenly than a 6-piston, providing superior feedback and consistent performance when you need it most. After a full year of real-world testing, the SL8 is the proven, hassle-free solution for serious stopping power.

Frequently Asked Questions

What makes the SL8 a "direct-fit" caliper?
The SL8 has a specially engineered narrow body. This allows it to deliver the power of an 8-piston caliper while still fitting behind over 90% of factory 19" to 21" wheels, saving you the cost of new wheels and spacers.
Why choose an 8-piston caliper over a 6-piston?
For larger, heavier vehicles, an 8-piston caliper applies braking force more evenly across a bigger brake pad. This leads to better heat management, reduced pad wear, and a more solid, confident pedal feel under heavy braking.
What's included in the complete SL8 brake kit?
This is a complete, bolt-on front axle upgrade. The kit includes:
  • 2 × SL8 Forged 8-Piston Calipers
  • 2 × Two-Piece Floating Brake Rotors
  • 1 × Set of Performance Brake Pads
  • 2 × CNC-Machined Caliper Mounting Brackets
  • 2 × Stainless Steel Braided Brake Hoses
Notice

Brake Kit Purchase Notice


  • Custom‑made products cannot be returned unless there is a genuine quality defect.
  • Spacer requirements vary depending on wheel design; we assist with fitment, but spacer‑related issues do not qualify for returns.

  1. Please provide vehicle make, model year, VIN, and wheel size before ordering TTSPORT products.
  2. Confirm wheel measurements and submit photos as requested — TTSPORT is not liable for issues arising from incorrect specs.
  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.
