The build: what's actually on this W214
| Component | On this car | Why it's set up this way |
|---|---|---|
| Vehicle | Mercedes-Benz E300 (W214) | Standard E-Class as the base, not an AMG car from the factory |
| Front | AMG 6-piston fixed caliper + 390mm carbon-ceramic rotor | The big front rotor is built around the AMG caliper, not the stock setup |
| Rear | AMG single-piston caliper + 360mm carbon-ceramic rotor | Configured to keep the factory electronic parking brake working |
| Pads | STOPFLEX low-dust ceramic compound | Matched to the rotors to keep the wheels clean |
| Axle scope | Front and rear carbon-ceramic conversion | Both axles upgraded as one package |
| Weight saved | About 22 kg / 48 lbs | Project figure for this front-and-rear retrofit |
Read this before you order
This is not a bolt-on rotor swap for the stock E300 floating front calipers. The 390mm front carbon-ceramic disc is built to run with the AMG 6-piston fixed front caliper. The caliper hardware is part of the package, not an afterthought.
What changes day to day
| STOPFLEX feature | Why it matters on a W214 | What you notice |
|---|---|---|
| Carbon-ceramic rotor, about half the weight of same-size steel | Less unsprung mass at each corner for a comfort-tuned sedan to control | The car settles a touch quicker over expansion joints and broken pavement |
| Low-dust pad and rotor pairing | W214 wheels are open multi-spoke designs that show every bit of dust | Wheels stay clean far longer between washes |
| Rotors that don't rust | Iron discs grow a rust ring after rain or a wash and look tired fast | The brake faces stay clean-looking through wet weather |
| 390mm front rotor behind a 6-piston caliper | Stock floating calipers look lost behind 19s and 20s | The brakes finally fill the wheel and match the car's exterior |
| Long street life off the track | A daily E-Class racks up miles without hard track abuse | Roughly 250,000 to 300,000 km of street service is realistic |
What gets better
- Less unsprung weight for the suspension to manage at each wheel.
- Very low brake dust with the matched STOPFLEX pads.
- No rust ring after rain or a wash.
- An AMG-style brake presentation that fills the wheel.
- Street life that can run into the hundreds of thousands of km off-track.
What to confirm first
- Whether your car has, or can take, the AMG 6-piston front caliper this front rotor needs.
- Wheel clearance: a 390mm front rotor is tight behind many 19-inch wheels, so check barrel depth and spoke shape.
- That the rear setup will keep your factory electronic parking brake working.
- Which payoff you care about most: cleaner wheels, no rust, less unsprung mass, or the AMG look.

FAQ
Will these rotors bolt onto my stock E300 calipers?
No. The standard E300 floating front calipers are not the match for this package. The 390mm front carbon-ceramic rotor is built around the AMG 6-piston fixed front caliper, so that hardware has to be part of the build.
Do 390mm front rotors clear 19-inch wheels?
They can, but it's tight. A 390mm rotor behind an AMG 6-piston caliper sits near the upper limit for a lot of 19-inch wheels, so confirm barrel depth and spoke shape before you order.
Is carbon ceramic overkill on a daily-driven E-Class?
Not really. On a daily-driven W214 the wins you actually feel are far less brake dust, rotors that don't rust, less unsprung weight at each corner, and a brake package that finally looks right behind the wheels rather than pure track use.
Does the rear upgrade keep the factory electronic parking brake?
Yes. The rear configuration pairs a 360mm carbon-ceramic rotor with an AMG single-piston rear caliper and is set up to retain the factory electronic parking brake function.
How long do STOPFLEX carbon-ceramic rotors last on the street?
A long time. Kept off the track, STOPFLEX carbon-ceramic rotors can reach roughly 250,000 to 300,000 km of street use, well past what most owners expect from factory iron discs, depending on how you drive and maintain the car.
