I've had these on for about 4000 miles now and I can say I like them very much. They are very low dust and stop on a dime. Only the very first stop is a little slow, but thats to be expected from ceramic pads. They were a bress to install and look to be very well made. After reading several reviews on here and other websites, I decided to try these. I never really read too much about anyone using these on there C's but I can tell you first hand, they're great!

Since having these on, I seem to never have brake dust on my wheels. Super clean and quite. Very good pads

W203 2005 Sport Sedan with dual piston fronts.

 

Info on where to read about them, and how much did you pay ?

 

I did a search on here and benzworld.org and read some of the threads about them. Most were for a ML but gives you a good idea. I also Google'd Rotex Gold pads and found a couple of things there. I bought them from Brakeworld.com for like $60+/- for the fronts and $57 for the rear. So far I love them, been 4 days since last wash and still no dust (I drive like 50 miles a day with highway/city mix) Well worth the money.

 

My dad used those on his 99' E320... they were really good, a lot less dust than OE.

 

sound good
maybe i'll use them next time
that's like a year away or more, since I just replace all 4 last month
