My car came equipped with the smallest brakes the Sports Package has to offer, 295mm cross drilled rotors.
Looks so small and puny and doesnt match the overall stance of the car
IMO.



So I swapped them for 350 brakes :


Now were talking


C300 cars have the same stock setup as my car, here is what you need if you want to upgrade:

2x Rotors A204 421 10 12 (cross drilled, also available without holes)
2x Caliper carrier A204 421 11 94
2x Spring A000 993 46 07
1x Left caliper A204 421 35 81
1x Right caliper A204 421 36 81
1x Pads A005 420 10 20

Nice upgrade

Think a Brembo big Brake kit cost the same?? Not for you, but normaly these oem calipers are expensive or not?

Mr Enigma

What's the price for the upgrade?

vic viper

Counting with todays rates I would say around 1250 Euros

Looks good! How about the rears? I have a C350 with that setup in the front but my rears are different, would it be possible to retrofit a OEM setup with drilled rotors in the rear?

You should be able to get aftermarket cross drilled rotors

Good job,

I'm looking to get BBK but, I'm still trying to convince my wife to let me spend 5K

I'd be nice to get a BBK up front and somehow use the front setup in the rear.

Very interesting and looks nicely done.....What about the issues of front/rear proportioning? This would seem to invite the tail end get very light under braking?

I don't know which discs the 204.089 has but in my opinion the brakes are far too sensitive, it makes driving uncomfortable. Perhaps I should buy your old discs, I assume it would allow 16 inch winter tyres too which is not possible with the current discs on our 204.089. Bigger discs look a lot better but I'm too old to care about the looks.

vic viper

204.089 use the same size rotors as my above upgrade, 320mm

16" wheels do work on this setup, at least the OE wheel "Pristix" wich I have tested.

I think MB does the best looking brakes as standard OEM than any other brand (within reason). Great choice on the upgrade.

Azn_C300

You mean MB outsourced the best looking brakes as standard OEM :p Our brakes were outsourced to Continental. C63s were outsourced to Brembo.

You answered my long-time question. You can't just swap carriers and rotors. Rats!

vic viper

There is a small downside, the new brakes are at least 30% heavier than the previous setup

The 295mm caliper is made entirely out of aluminum and is very light, the 320mm caliper is mostly steel and only part aluminum.

Vic: Are they 2 or 4 pistons?

vic viper

Theyre one piston floating calipers.

vic viper

They are one piston floating calipers.

This gets more and more common on newer cars now, theyre alot lighter and not as complex as multiple piston calipers, its also easier to replace pads on a floating caliper.

Multiple piston calipers are though still often found on more extreme cars.

Krytech

Good to know, I've often wondered how much heavier my rotors where than the C300.

Do you notice any difference driving over choppy roads?

vic viper

No, I actually havnt fel any difference in acceleration or uneven surfaces.

albert101

Did you replace the rears or just the fronts? Or are the rears the same on your car and the C350? Great upgrade! I was thinking about doing the same on mine. Do you feel an improvement in braking power?

vic viper

Yes, the brakes feel a lot firmer now, it feels that I have a alot of stopping power if I would need it,

The rears are still stock but the only real difference there is that the 350 rear brakes are ventilated, there is not much diameter difference.

Vic, another good job on the upgrade and the procedure:

I found these prices sofar:

2x Rotors A204 421 10 12 (cross drilled, also available without holes) - $50.40 ea.
2x Caliper carrier A204 421 11 94 - $124 ea
2x Spring A000 993 46 07 - $8.00 ea
1x Left caliper A204 421 35 81 - $334
1x Right caliper A204 421 36 81 - $326
1x Pads A005 420 10 20 - $73.60

Sincity

I see. I thought they would be 2-piston or 4-piston front calipers like the w204 Sport packaged cars.

Do you know of a source for rear cross drilled rotors?
