Honda Odyssey Big Brake Kit Upgrade / TTSPORT Slim SL6
Japanese OEM brake systems are usually tuned for durability and everyday economy, not for hard stops. Push a stock Odyssey's brakes in an emergency or on a long downhill grade and that soft, sinking pedal shows up fast — and it chips away at driver confidence right when you need it most. This case swaps the factory setup for a TTSPORT SL6 six-piston big brake kit that bolts on behind the stock 18-inch wheels.
TTSPORT designed the SL6 kit specifically for owners who don't want to change wheels or add a flange adapter to fit a bigger brake. The six-piston caliper drops in behind factory 17-18 inch wheels, cutting both the install complexity and the cost of the upgrade compared to a kit that forces a wheel swap.
With the caliper and rotor mounted, the factory wheel goes back on with no spacers and no rubbing. The six unequal-diameter pistons apply clamping force more evenly across the pad, which is what gives the pedal a firmer, more linear feel instead of the vague travel of the stock single or dual-piston caliper.

Why It Works
- Direct fit on 17-18 inch OEM wheels — no spacers, no flange adapter, no need to buy new wheels to run the bigger caliper and rotor.
- Two-piece forged caliper body with a through-bolt tie rod adds rigidity, so the caliper flexes less under hard braking and the pedal feels more solid and consistent.
- Six unequal-diameter pistons spread clamping force more evenly across the pad, giving a more linear brake feel and better modulation than a single or dual-piston OEM caliper.
- An open, lightweight caliper design improves heat dissipation, which helps reduce thermal fade and keeps braking performance more consistent under repeated hard stops.
- The 355mm high-carbon rotor offers better thermal stability and wear resistance than a standard rotor, which should extend service life on the brake system as a whole.
