Volkswagen CC Big Brake Kit Upgrade / TTSPORT Classic 8703

The Volkswagen CC has a reputation for being one of VW's best-looking sedans, but its factory brakes were never built for spirited driving. We'd previously fitted this same CC with a TT9040 six-piston kit and larger rear rotors; this time around, the owner brought the car back in for a front-axle upgrade to the TTSPORT Classic 8703 kit — a monobloc six-piston caliper paired with a 380x34mm high-carbon rotor, running behind the car's factory 19-inch wheels.

The kit is built around an aluminum-alloy caliper cast as a single piece rather than bolted halves, which keeps the caliper body rigid under hard braking. The opposed six-piston layout is designed to clamp the pad more evenly across its surface, and the caliper carries dust-boot seals that are meant to cut down on maintenance over time.

Vehicle & Kit Specs

Here's the hardware that went on this particular Volkswagen CC:

Why It Works

• One-piece monobloc casting on the 8703 caliper resists the flex a two-piece bolted caliper can develop under repeated hard stops, which helps the pedal stay firm and consistent rather than going soft.
• The six opposed pistons apply pressure across the pad more evenly than the CC's factory single-piston sliding caliper, giving a more linear feel as pedal pressure increases.
• The 380x34mm rotor is far larger and thicker than the stock disc, adding surface area and mass that help absorb and shed heat during repeated braking instead of fading.
• The directional vane pattern is designed to sweep dust off the pad face and pull air through the rotor for cooling, versus the solid, non-vented factory disc.
• Stainless steel lines don't balloon under pressure the way rubber hoses can, cutting out the mushy delay that comes from line expansion.

With the vehicle-specific bracket in place, the caliper and rotor mounted right in the factory location and cleared the CC's stock 19-inch wheels — no spacers needed.
