Honda Accord (CY1) Upgraded with TTSPORT Slim SL6 Big Brake Kit

04 Jun 2025

The Honda Accord is the undisputed king of reliable, sensible daily drivers. But in the automotive world, "sensible" usually translates to "soft." If you drive spiritedly, you know the feeling: that stock brake pedal feels like stepping on a wet sponge. It is vague, uninspiring, and in a panic stop on the highway, it can feel downright scary.

Enthusiasts often look at Big Brake Kits (BBKs) to fix this, but they hit a massive financial wall: most kits require you to buy expensive 19-inch or 20-inch aftermarket wheels just to clear the calipers. For a practical daily driver, that is a non-starter.

This is the exact problem we solved. The TTSPORT SL6 "Slim Series" is a full 6-piston forged caliper upgrade engineered specifically to fit behind most 17-inch and 18-inch factory Accord wheels. No spacers, no new wheels, no hassle. It is the "smart" performance upgrade.

The Bolt-On "OEM+" Upgrade

This is a complete front-axle solution. It gives you the stopping power of a sports car while maintaining the practical, factory appearance of your Accord. It bridges the gap between a commuter car and a sport sedan.

  • Vehicle Platform: Honda Accord (Gen 9 / Gen 10 / Gen 11)
  • Wheel Requirement: Fits most 17" & 18" OEM wheels
  • Caliper: TTSPORT SL6 "Slim Series" 6-Piston Forged Caliper
  • Rotor: 345mm (13.6") High-Carbon 2-Piece Rotor
  • The Kit: Includes vehicle-specific brackets, street-performance pads, and stainless steel lines.

Kills the "Mush," Keeps the Wheels

How does the SL6 transform the driving experience? It comes down to rigidity and thermal capacity.

1. Rock-Solid Pedal Feel

Stock calipers are "floating" designs that flex under pressure, causing that mushy feel. The SL6 is a forged 6-piston fixed caliper. Because it is forged, we can make the walls thinner (for clearance) without sacrificing stiffness. All your pedal effort goes directly into clamping the rotor, not bending the caliper.

2. Real Stopping Power

We replace the heavy one-piece stock rotor with a 345mm (13.6") 2-piece rotor. This increased diameter provides more mechanical leverage, while the 2-piece design dissipates heat significantly faster. This means no brake fade during canyon runs or repeated heavy stops.

3. The "No-Hassle" Geometry

This is the key. We used 3D scanning to profile the inner barrel and spokes of the factory Accord wheels. The SL6 caliper body is shaped specifically to nestle into that tight space, saving you thousands of dollars on a new wheel and tire package.

Honda Accord Upgrade FAQ

1. Do I need wheel spacers?

In most cases, no. The "Slim Series" (SL6) is designed to clear standard Honda wheel offsets. However, Honda makes many different wheel styles. We strongly recommend using our fitment template to check your specific wheels before ordering.

2. Is this kit noisy for daily driving?

No. We understand the Accord is a daily driver. We ship this kit with our Street-Performance Ceramic Pads, which are formulated to be quiet and low-dust while still offering significantly more bite than stock.

3. Will this work with the Honda Sensing system?

Yes. The TTSPORT brake system is purely mechanical/hydraulic and does not interfere with the radar or camera systems used for Honda Sensing (Collision Mitigation Braking, Adaptive Cruise Control, etc.).
