Confirm this before you order
This kit is built around the factory caliper setup. The 992 was sold with more than one brake configuration depending on options and market, so check your exact front and rear setup against the spec above before buying. If anything's different, run your VIN and current brake hardware past us first.
What carbon ceramic actually changes on this car
| STOPFLEX feature | Why it matters on a Targa 4 | What you notice |
|---|---|---|
| Carbon ceramic rotor, ~half the weight of steel | The Targa carries extra weight up top from its roof mechanism, so trimming rotating mass at each corner is worth more here than on a base Carrera. | Lighter steering off-center and a chassis that settles quicker over broken pavement. |
| Low-dust pad pairing | Open-spoke 911 wheels show every speck of iron dust, and this car gets washed and photographed a lot. | Wheel faces stay clean for weeks, not days. |
| No-rust ceramic rotor face | A Targa often sits between weekend drives. Iron rotors flash-rust overnight after rain or a wash. | No orange film on the rotor face when you pull it out of the garage. |
| High-heat friction stability (~0.3μ at 900°C) | Long descents and back-to-back canyon runs heat-soak iron rotors and soften the pedal. | Pedal feel that holds up on the third hard stop the way it did on the first. |
| Long-fiber CCB construction | This is a car people keep, so durability of the rotor itself matters over the long haul. | Street service life rated around 250,000–300,000 km when kept off the track. |
What gets better
- Far less brake dust on the wheels with matched STOPFLEX pads
- No surface rust on the rotors after rain or washing
- Less unsprung and rotating mass at all four corners
- More consistent pedal on long grades and spirited road driving
- Long street service life, so it's a keep-the-car decision, not a consumable
What to confirm first
- Your exact factory front and rear brake configuration
- That the car retains its original calipers
- Front and rear rotor sizes match the 410/390 mm spec
- Wheel and market variant, since the 992 had options-based brake setups
If you're not sure your car matches the spec shown here, send us your VIN and current brake details and we'll confirm Porsche 911 Targa 4 (992) fitment before you order through our Porsche CCB collection.

FAQ
Is a carbon ceramic brake upgrade worth it on a mostly street-driven 911 Targa 4?
Yes. On a street-driven Targa 4, the day-to-day wins are what you feel most: cleaner wheels, no rotor rust, and less unsprung weight at each corner. That makes it as much an ownership upgrade as a performance one, especially for touring and canyon miles.
Does this STOPFLEX setup keep the factory calipers on the 992 Targa 4?
Yes. This is a direct-fit rotor replacement built around the factory brake system. It swaps the iron rotors for STOPFLEX carbon ceramic rotors and keeps your original calipers, rather than converting the car to a different caliper package.
Will carbon ceramic rotors cut brake dust on the Porsche 911 Targa 4 (992)?
Yes. Paired with STOPFLEX pads, dust output is very low next to a typical iron setup. On open-spoke 911 wheels with a bright finish, that means the faces stay clean much longer between washes.
Do STOPFLEX carbon ceramic rotors rust after rain or a wash?
No. Carbon ceramic rotors don't corrode like iron, so you won't get the orange surface rust that shows up on steel rotors after the car sits wet overnight.
How long do STOPFLEX carbon ceramic rotors last in street use?
Kept off the track and used on the street, STOPFLEX rates rotor life at roughly 250,000 to 300,000 km, well beyond what you'd expect from typical steel rotors.
