DR6 Front 6-Piston Drift Big Brake Kit
The DR6 front big brake kit is built around the DR6 Racing Series — Drift caliper: a two-piece forged 6-piston body with staggered 27 / 32 / 38 mm pistons, paired with solid two-piece iron rotors and application-specific brackets, hats, and braided lines. It targets the things that actually win drift events — repeatable bite, fast pressure rise, clean modulation into lock-up, and predictable release during transitions.

Why Builders Choose the DR6
Drift cars do not need raw stopping distance alone — they need a front axle that responds the instant the driver loads the pedal, then releases without dragging mid-transition. The DR6 total piston area of 50.2 cm² per caliper is sized to deliver strong initial bite on a 330–355 mm rotor without overwhelming hydraulic balance against the OE rear or a hydraulic handbrake circuit.
Two-Piece Forged Body
Two-piece forged aluminum construction keeps caliper weight at 2.50 kg per side without pads, reducing unsprung mass and improving wheel-speed response.
Solid Two-Piece Rotors
Ø330 / 343 / 355 mm solid two-piece rotors use heat-treated high-carbon iron with directional curved-slot faces for clean pad refresh.
Racing Pistons Without Dust Boots
Open-piston construction is designed for high-temperature service intervals, easy seal inspection, and quick rebuilds.
Linear Pedal Feel
Pedal pressure stays linear, and the solid rotor mass holds heat predictably across back-to-back runs.
Vehicle-Specific Engineering
Brackets, hats, and brake-line fittings are built to your chassis, knuckle, wheel offset, and competition use case.

The Bespoke Engineering Process
Every DR6 front drift system is engineered around the vehicle’s front knuckle, hub location, rotor hat offset, wheel barrel, spoke clearance, brake line routing, master cylinder, rear circuit, hydraulic handbrake layout, front brake bias target, and intended drift, time-attack, or rally use. The goal is not a generic universal fit; the goal is a front brake package that delivers repeatable bite, fast pressure rise, clean modulation into lock-up, and predictable release during transitions.
1. Technical Consultation
We review the chassis code, front knuckle and hub setup, wheel spec, master cylinder, rear circuit, hydraulic handbrake use, target front brake behavior, tire package, event format, and whether the car uses OEM or custom front uprights.
2. Data Submission
For OEM knuckles, provide chassis code, knuckle / hub setup, wheel diameter, width, offset, spoke profile, master cylinder, and rear circuit details. For custom front uprights, provide CAD files, technical drawings, hub-face data, rotor mounting dimensions, or accurate bracket mounting-point measurements.
3. Engineering Review & Approval
TTSPORT confirms rotor size, caliper bracket geometry, rotor hat offset, brake line fittings, wheel clearance, brake balance, line routing, and bedding requirements before production begins.
If you are unsure whether your wheel, front knuckle, rotor offset, master cylinder, rear circuit, or hydraulic handbrake layout is suitable, Contact us before ordering so the engineering team can review the build details.
Installation & Break-In
- This kit is engineered for drift, time attack, rally, and closed-course motorsport use.
- DR6 uses radial-mount calipers with vehicle-specific brackets and application-specific brake line fittings.
- Brackets, hats, and brake-line fittings are built to your chassis, knuckle, wheel offset, and competition use case.
- Choose 330 mm for lower rotational inertia and quicker wheel-speed response on lighter chassis or shorter session formats.
- Choose 343 or 355 mm when chassis weight, entry speed, or session length increases heat load.
- Two-piece caliper construction supports seal and piston service without removing the bracket from the knuckle.
- Open-piston design, without dust boots, speeds inspection between sessions and tolerates sustained high pad temperatures.
- Two-piece rotor design allows iron ring replacement against the original aluminum hat.
- Bedding-in is required before competitive use to transfer pad material evenly and stabilize friction.
- Always verify front / rear brake balance after install.
Motorsport use: Bedding-in is required before competitive use. Pads operate up to 600 °C and are intended for iron / steel rotors only. Always verify front / rear brake balance after install.
Frequently Asked Questions
What chassis is the DR6 designed for?
The DR6 is a Racing Series — Drift caliper. It is built to order with vehicle-specific brackets, rotor hats, and brake-line fittings, so it can be configured for popular drift, time-attack, and rally chassis running 17 in or larger wheels. Send your chassis details and TTSPORT will confirm fitment before production.
330 mm, 343 mm, or 355 mm rotor — which should I run?
Run 330 mm if you want lower rotational inertia and quicker wheel-speed response on a lighter chassis or shorter session format. Step up to 343 or 355 mm when chassis weight, entry speed, or session length increases the heat load.
Why do the calipers have no dust boots?
Open-piston racing construction tolerates sustained high pad temperatures better than booted street pistons and makes between-session seal inspection faster. It is intended for race-prepared cars that see regular brake service.
Will this throw off my front-to-rear brake balance?
The 50.2 cm² total piston area on a 330–355 mm rotor is sized for strong front bite without overwhelming a typical OE rear or a separate hydraulic handbrake circuit. Re-check brake bias after install, especially if the master cylinder or rear setup has been changed.
Can the rotor rings be replaced separately?
Yes. The two-piece rotor uses a CNC-machined aluminum hat and a heat-treated high-carbon iron ring, so the iron friction ring can be replaced against the original hat to reduce running cost across a season.
Is bedding-in really required?
Yes. The pad and rotor friction couple needs a controlled bedding cycle to transfer pad material onto the rotor face evenly. Skipping this step causes uneven deposits, vibration, and reduced bite under load.
Ready to spec your DR6 drift build?
Send your chassis code, knuckle / hub setup, wheel spec, master cylinder, rear circuit, and hydraulic handbrake layout. TTSPORT will confirm rotor size, bracket geometry, brake balance, rotor hat offset, and line routing before production.

**UPDATE ON PDT*** Ingredients changed
Ok here’s my update (4/4/26)
We loved it. It did what it was supposed to do in the beginning but now I stopped using the product. Ingredients must’ve changed. It’s now a darker color, it doesn’t dissolve like it did in the past, and worst part— my daughter’s hair started breaking off. It could just be her hair but I don’t want to take chances. The ingredients definitely changed.
We are trying azure batana and will stick with it for 3 months to see results. But as of now their product looks like the real deal. It’s a shame because I like consistency. I’ll stick with one product for years. Oh well. Tossed this one out.
(Pic 1-2 AFTER USING; Pic 3 BEFORE USING)
Yes it works. It smells so if you’re sensitive to smells, you might only want to use it as a deep conditioner. Both my daughter & I are adjusted to the smell and love the results so we can easily prioritize our results over the less than fragrant odor. But the results!!!
My daughter lost 40% of her hair a yr ago to severe scalp ezcema (+ a trip to St Martin’s beautiful yet salty water). We used other products with marginal success. I started using this product 2 months ago & I already see results. We use it twice weekly as a spot treatment along the crown & nape of her head, and deep condition with it twice monthly. Her locs are growing and more importantly, her edges and nape are recovering tremendously. We’re going to keep at it!! We like the texture (moist but not sticky), it leaves her locs moisturized but not weighed down. Her hair is drinking it up. Will repost after 2 more months.

The smell.
It really does smell like coffee. Contrary to some of the comments, the coffee smell doesn't go away right away.
Waiting to see the results.

Makes my hair shine.

This product makes my hair smell good and shiny. You only need to use a small amount for results. I am sure my hair will grow since oil is good for your hair.
