Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2007-2012 Porsche 911 (997) Targa. This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2007-2012 | Brembo OEM Porsche 911 GT3 6-Piston Caliper / 405mm | Brembo OEM Porsche 911 GT3 4-Piston Caliper / 390mm | 21" |
This kit is built per car, not per platform. We engineer the brackets, rotor-hat offsets, and caliper mounting to your confirmed model and trim, because trims sharing a chassis name frequently differ underneath — performance variants can run different knuckles, hub geometry, and wheel ET clearance than their standard siblings. You receive calipers, pads, rotor hats, floating hardware, and brake lines as one matched, trim-specific system. Cars with modified knuckles, uprights, or non-factory suspension mounting points need review before ordering.
The 405 mm rotor sets the minimum wheel size at 21" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |

| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 mm |

Why Carbon Ceramic — and Why StopFlex
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
Winter & Cold-Weather Braking
Cold facts first: an untuned ceramic disc bites less than iron on a freezing morning — physics, not a defect. StopFlex tuned both the pad compound and the disc's ceramic coating for cold starts, so winter cold-car braking now feels very close to summer. Leave extra margin on the very coldest first stops; severe-climate daily drivers should build Street Spec.
Caliper Overview
Front Caliper
The front runs the Brembo OEM Porsche 911 GT3 6-piston caliper clamping a 405mm carbon-ceramic rotor, so you get genuine GT3 caliper provenance and consistent pedal pressure across repeated hard stops.
Rear Caliper
The rear pairs the Brembo OEM Porsche 911 GT3 4-piston caliper with a 390mm carbon-ceramic rotor to add rear thermal capacity and keep braking balanced under sustained load.
Choose Your Rotor: Street, Track-Day, or Motorsport
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.
Heat Management Note
High rotor temperature tolerance does not mean heat management disappears. Under repeated hard braking, heat migrates into the pads, brake fluid, seals, calipers, and wheels even when the ceramic disc itself is comfortable. Plan brake cooling and high-temperature fluid for extended track sessions, long mountain descents, or sustained aggressive driving.

FAQ
How do these brakes behave on a cold winter morning in the 997 Targa?
Any carbon-ceramic disc bites a little less when it's stone cold compared to cold iron — that's physics, not a fault. On this kit we tuned both the pad compound and the ceramic coating for cold starts, so first-stop feel on a cold 997 comes very close to summer feel. Leave a little extra following distance on your first couple of stops on the coldest days and the system warms in fast.
Will this fit my exact 997 Targa or Targa S?
We engineer every kit to your confirmed trim. Targa and Targa S share the chassis name but can differ in front upright geometry and wheel clearance, so the brackets, rotor-hat offsets, and caliper mounting are cut specifically for your car. We do not make a platform-wide bolt-on claim — send us your VIN and trim and we match the hardware to it.
What wheels do I need to clear the 405mm front rotors?
The 405mm front rotor with the GT3 6-piston caliper requires a minimum 21-inch wheel. Anything under 21 inches will not clear the caliper, and spoke shape matters too — some 21-inch wheels foul the caliper body. Send us your wheel model and we'll confirm clearance before you order.
Will the factory pad-wear warning still work?
Yes. This kit includes pad wear sensors that are fully compatible with the 997's OEM wear-sensor system, so your factory pad-wear light keeps functioning with no dashboard errors. The pads use a carbon-ceramic-specific low-metallic resin compound with an average friction coefficient near 0.44 and heat resistance to about 750 °C.
