The Lightweight Leader: DRT4 Forged 4-Piston Drift Caliper

Engineered for competitive drift cars where shedding every ounce is critical, the DRT4 is the ultimate solution in lightweight braking performance. This ultra-compact 4-piston caliper is forged from high-strength aluminum, providing maximum rigidity at a featherlight 1.41kg to sharpen steering response and vehicle agility.

Purpose-built for the unique demands of drifting, the DRT4 is paired with a specialized thin, solid rotor to deliver the instant, aggressive lock-up and rapid thermal response needed for high-speed entries and quick transitions. Featuring bootless racing pistons for unmatched heat resistance, this custom-built system provides the consistent, reliable performance that professional drift builds demand.

Bespoke Fitment & Ordering Process

Step 1: Technical Consultation

Initiate your order by contacting our motorsports engineering team. We will conduct a detailed consultation to understand your vehicle, competition class, and specific performance requirements.

Step 2: Submit Specifications

For Factory Knuckles: Provide vehicle year, make, model, and detailed wheel specifications.

For Modified Knuckles: Provide detailed measurements, technical drawings (CAD files preferred), or high-resolution photos of the custom knuckle assembly.

Step 3: Engineering & Approval

Our engineers will design the bespoke mounting hardware for your application. We will provide you with the final design specifications and production timeline for your approval before manufacturing begins.

Frequently Asked Questions

Why is this kit specifically for drifting?
The DRT4 is purpose-built for the unique physics of drifting. Its incredibly low weight (only 1.41kg per caliper) sharpens suspension response for faster transitions. The thin, solid rotors provide the instant, aggressive bite needed for high-speed entries, while the bootless racing pistons ensure maximum heat resistance during repetitive lock-ups.
Is this kit suitable for street use?
No. This is a competition-only braking system. The lack of dust boots on the racing pistons requires a professional maintenance and inspection schedule. The aggressive nature of the solid rotors is not designed for the varied conditions of daily driving.
What information is required for a custom order?
For a vehicle using **factory steering knuckles**, we require the year, make, model, and detailed wheel specs. For a **fully custom or modified knuckle**, we require technical drawings, CAD models, or precise measurements of the mounting points to engineer a perfect bolt-on solution.
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. Disclaimer

  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.
