Slim Series · Front Axle · 6-Piston
The TTSPORT Slim SL6 is a front-axle 6-piston big brake kit engineered for drivers who need stronger, more repeatable stopping power without jumping to an oversized caliper package. A forged aluminum body, staggered 28/30/36 mm piston layout, and a slim 120 mm caliper height keep wheel-clearance requirements practical for many 17-inch and larger setups.
Stiffer body for sharper pedal feel and consistent piston travel under load.
28/30/36 mm pistons balance pad pressure across the leading and trailing edges to reduce taper wear.
Heat-insulated pistons with dust boots limit fluid temperature rise during back-to-back stops.
330 or 355 mm × 28 mm vented discs with CNC aluminum hats for heat capacity and reduced unsprung mass.
Three-layer PTFE / SUS304 / PVC construction for firm pedal modulation.
Designed for tighter spoke profiles where standard 6-piston bodies will not clear.

2 × SL6 forged 6-piston front calipers (left / right)
1 set high-temperature performance brake pads for both front calipers
2 × Two-piece directional rotors (330 mm or 355 mm × 28 mm)
2 × CNC carbon-steel caliper brackets, vehicle-specific
2 × CNC aluminum rotor hats
1 set stainless steel braided brake lines with vehicle-specific fittings
Mounting hardware is included.
Wheel spoke shape, rotor hat offset, and vehicle-specific bracket geometry all affect real-world fit. Measure your wheel against the SL6 caliper envelope (350 × 135 × 120 mm) before purchase, or request a fitment template from our team.
The SL6 requires a 17 in or larger wheel.
The SL6 requires a minimum 82 mm spoke clearance.
Confirm year, make, model, trim, and front hub/spindle details at checkout so we cut the correct brackets.
Many factory and aftermarket 17s clear, but spoke shape and barrel profile matter. Send us your wheel make/model or a tracing and we'll confirm before you order.
The SL6 needs at least 82 mm of spoke clearance and a 17 in or larger wheel. Many factory and aftermarket 17s clear, but spoke shape and barrel profile matter. Send us your wheel make/model or a tracing and we'll confirm before you order.
Pick 330 mm for tighter wheel packages or lighter unsprung mass. Pick 355 mm when you want the largest swept area, more thermal headroom for repeated hard stops, and slower pad temperature rise on long descents or track days.
Not required. The SL6 front kit is designed to add front clamp force without forcing a rear-bias change on most platforms. If you do significant track use, a matched rear upgrade can rebalance the system, but the front kit can run as a standalone upgrade.
In most street and fast-road applications, no. The 46.8 cm² total piston area is sized to work with stock master cylinders on most platforms. Hard track use with very aggressive pads may benefit from a larger master, but it is not required out of the box.
Yes. New pads and rotors must be properly bedded to lay an even transfer layer on the rotor face. Skipping this step causes vibration, uneven bite, and shortened pad life. We supply a bedding procedure with every kit.
Yes. Each kit ships with CNC carbon-steel brackets and braided line fittings matched to your declared vehicle. Confirm year, make, model, trim, and front hub/spindle details at checkout so we cut the correct brackets.

Brake Kits · Fitment · Installation · Care Guide
A brake kit is not just a pair of larger calipers. Calipers, rotors, pads, hoses, brackets, rotor hats, mounting hardware, brake fluid, wheel clearance, and bedding procedure all work together as one system.
This guide explains how to confirm the right TTSPORT brake kit before ordering, what to check before installation, and how to care for the system after installation.
Do not order a brake kit by vehicle name alone. The correct kit depends on the vehicle, axle position, wheel package, driving use, and brake system layout.
Brake kits are application-specific. A visually similar kit can still have the wrong rotor offset, bracket geometry, hose fitting, caliper position, or wheel clearance requirement.
Different TTSPORT brake kit series use different hardware layouts. Always confirm what the kit includes before purchase.
Use direct-mount calipers and one-piece rotors where specified. These kits do not use rotor hats or caliper brackets unless the final product page clearly states otherwise.
Use separate friction rings and rotor hats. Hat offset, ring bolt pattern, hardware style, and rotor direction must be matched correctly.
May require bespoke brackets, rotor hats, brake lines, and engineering confirmation based on knuckle, hub, wheel, and competition use.
Require extra attention to wheel clearance, tire size, vehicle load, descent control, hose routing, and dust / water exposure.
Do not assume every brake kit includes the same parts. Package contents vary by product series, vehicle application, and final order configuration.
Before finalizing the order, review the kit specification carefully. Confirm the brake kit is matched to your vehicle and wheel setup, not only to the model name.
If any part is not listed in the final order or product page, do not assume it is included.
Inspect every component before installation. Do not modify, grind, drill, stretch, force, or space brake kit components to make them fit.
Safety: Brake kits affect braking force, hydraulic sealing, heat control, wheel clearance, and vehicle stability. Do not install the kit if fitment, torque, direction, clearance, or compatibility is unclear.
Correct installation is as important as the brake kit itself. A properly engineered kit can still perform poorly if installed with dirty mounting faces, incorrect torque, poor hose routing, or trapped air in the hydraulic system.
Verify caliper centering over the rotor and confirm even pad sweep across the friction surface.
Confirm left / right rotor direction if the rotor uses directional vanes or directional face pattern.
Check brake hose length and routing at full steering lock and full suspension travel. No twisting, rubbing, stretching, or kinking.
Check caliper-to-spoke and caliper-to-barrel clearance before road use. Wheel diameter alone is not enough.
Use the correct brake fluid type and bleed the system until pedal feel is firm and consistent.
Torque all brake hardware to the specified value. Do not reuse damaged, unknown, stretched, or corroded safety-critical fasteners.
Brake pads and rotors need a controlled bedding process before full performance is available. Bedding helps create an even transfer layer on the rotor surface, improving bite, pedal consistency, and vibration resistance.
Street pads, race pads, iron rotors, two-piece rotors, and carbon ceramic rotors may require different bedding procedures. Use the procedure supplied with the specific kit.
After installation and bedding, give the system a short break-in period before aggressive use. Pedal feel, pad contact, dust output, and noise may continue to settle after the first drives.
Brake kits need regular inspection, especially after track use, off-road use, towing, mountain driving, winter salt exposure, or any brake service.
Inspect pads, rotors, fluid level, and hose condition during normal service intervals. Prioritize quiet operation, smooth pedal feel, and even wear.
Check pad thickness, rotor surface condition, and fluid condition more often. Long descents create sustained heat even without track use.
Inspect for mud, sand, stone impact, hose abrasion, dust boot damage, and caliper contamination after trail use.
Inspect pads, rotors, fluid, and hardware before and after every event. Track heat shortens service intervals.
Check rear brake temperature, hydraulic handbrake behavior, pad wear, rotor cracking, and hardware condition frequently.
Use only compatible pads and approved bedding procedures. Inspect rotor surface condition carefully and avoid incompatible friction materials.
Do not continue driving if the brake system shows any of the following symptoms. Inspect the system or contact a qualified brake technician before using the vehicle again.
Send your vehicle details, brake kit series, wheel specs, driving use, photos, and any symptoms you notice. TTSPORT will help confirm fitment, installation checks, and the correct care path for your brake kit.
