Tech Spotlight: The Dual-Circuit Caliper That Dominated D1
In professional drifting, you can't have a "maybe." When you rip the hydro e-brake for a high-speed, backwards entry, you need *instant, predictable* lock-up. When you're left-foot-braking to manage your line, you need a *firm, consistent* pedal. What you *don't* need is a clunky, heavy, home-brew dual-caliper bracket that messes up your bias and gives you a mushy pedal. That's a compromise. We don't do compromises.
This is why four major pro teams in the D1 Grand Prix, one of the world's top drift series, run our dedicated drift-spec brake systems. We're not just a sponsor; we're a core technical partner.
At the recent D1GP Chengdu event, it was a total TTSPORT sweep. Our driver, Wang Qi of the DRS Drift Team, put on an absolute clinic. His car, running our pro-level system, landed on the podium *three times*: 1st Place (Solo Run), 3rd Place (Tandem), and 2nd Place (Tandem, Round 2). This is the proof.










The Championship-Winning Tech: DR6 & DR4+2
Wang Qi's car is running a setup we co-developed with him, built to solve the biggest problems in drifting. This isn't a "street kit" painted a flashy color—it's a purpose-built weapon.
Front: TTSPORT DR6 6-Piston Caliper
A forged, high-rigidity 6-piston caliper. It's designed to give a rock-solid pedal for left-foot-braking and has massive cooling ducts to survive the extreme heat of back-to-back tandem runs without a hint of fade.

Rear: The Game-Changer (DR4+2 Dual-Circuit Caliper)
This is the ultimate solution to the "dual-caliper problem." The DR4+2 is a **single, lightweight, monoblock caliper** with two *completely independent* hydraulic circuits.
- 4 Pistons for your Hydro E-Brake: Delivers insane, instant, and predictable lock-up.
- 2 Pistons for your Footbrake: Allows for perfect trail-braking and line correction.
- ZERO Interference: Because the circuits are separate, ripping the hydro has **ZERO effect** on your footbrake pedal. No fluid kickback. No mush. No compromise.
- Saves Weight: You get to *ditch* that heavy, ugly, home-brew bracket, saving massive unsprung weight.

The Driver's Verdict
Here's what D1 champion Wang Qi had to say:
"This TTSPORT system isn’t just 'strong'—it’s stable and precise. The rear caliper and hydro combo gives you so much control in extreme situations, letting you link transitions instantly. To be able to drift lap after lap in this heat and still have a clear, consistent pedal feel is just incredible."
