The build: what's bolted to this 992
| Item | Specification |
|---|---|
| Vehicle | Porsche 911 Carrera S (992) |
| Front setup | Akebono 10-piston caliper with 420 mm STOPFLEX carbon ceramic rotor |
| Rear setup | Brembo 4-piston caliper with 410 mm STOPFLEX carbon ceramic rotor |
| Pads | STOPFLEX low-dust ceramic street compound |
| Weight saved | About 26 kg (57 lb) total off the corners |
| Wheel requirement | 20-inch wheels |
| Scope | Custom front and rear big brake conversion |
Confirm this before you order
This is a custom big brake conversion, not a factory-size swap. A 420 mm front rotor under a 10-piston caliper lives or dies on wheel clearance, so your exact 20-inch wheel barrel and spoke shape need to be checked against the kit drawings before anything ships.
What the upgrade actually does
| STOPFLEX feature | Why it matters on the 992 Carrera S | What you notice |
|---|---|---|
| Carbon ceramic rotors, 420 mm front / 410 mm rear | A Carrera S carries real speed, and back-to-back stops from those speeds load any iron disc with heat fast. Carbon ceramic holds its friction as temps climb. | The pedal feels the same on the tenth hard stop as the first, instead of going long and soft. |
| About half the weight of same-size steel rotors | That 26 kg comes straight off unsprung, rotating mass at all four corners — the weight a chassis feels most. | Steering loads up quicker and the front end follows your hands with less lag over broken pavement. |
| 900°C friction holding near 0.3μ | Sustained high-speed braking and long downhill grades are where iron fades. Carbon ceramic keeps grabbing when it's glowing. | Confidence on a fast canyon run or a long descent, not a fading pedal halfway down. |
| Low-dust STOPFLEX pads | A 911 wears its wheels like jewelry, and black brake dust ruins the look between washes. | Wheel faces stay clean far longer, so you're not scrubbing barrels every weekend. |
| Rotors that don't rust | Iron discs grow an orange film after one rain or wash; on a car parked outside that shows. | The rotor face stays clean-looking through wet weather and sits behind the spokes the way it should. |
What gets better
- Heat headroom for repeated hard stops and long descents
- About 26 kg less unsprung mass for sharper steering and ride response
- Much cleaner wheels thanks to low-dust pads
- No rust film on the rotor faces after rain or washing
- Long street life — roughly 250,000 to 300,000 km off track
What to confirm first
- Your exact 20-inch wheel clears the 420 mm front rotor and 10-piston caliper
- Front barrel and spoke geometry against the kit drawings
- That a front-and-rear conversion matches your driving goals
- Pad and rotor pairing stays the STOPFLEX street combo for daily use

FAQ
Do you actually need a 10-piston front caliper on a 992 Carrera S?
For everyday street driving, the factory brakes are plenty. This build is for owners who want more heat headroom under repeated hard braking, a firmer pedal character, and a more aggressive look behind the wheel than stock.
Will 420 mm front rotors clear 20-inch wheels?
This package is designed around 20-inch wheel clearance, but a big rotor and 10-piston caliper need to be checked against your exact wheel design before ordering. Barrel shape and spoke clearance both decide whether it fits.
Can this carbon ceramic setup be driven every day?
Yes. It pairs large carbon ceramic rotors with low-dust STOPFLEX street pads, so you get the heat capacity without giving up normal daily manners.
Does it cut brake dust and rotor rust?
Yes. With STOPFLEX pads the wheels stay much cleaner, and the carbon ceramic rotors don't pick up the orange rust film that iron discs get after rain or a wash.
How long do STOPFLEX carbon ceramic rotors last on the street?
For street use that stays off track, STOPFLEX puts rotor life at roughly 250,000 to 300,000 km. Real-world life depends on how you drive, your pad choice, and maintenance.
