Front brake rotor size

Did you ever figure it out? The 300mm front rotor is standard and compatible with a 16 inch rim.

The 330mm upgrade calls for a 17 inch rim and up. I'm tempted to try it.

I did not, but I did end up ordering rotors from R1 concepts. The fronts are on the shelf waiting to be needed. They only listed 1 for the van.

Sounds good, thanks for your reply. Looks like the 330mm option is only offered in Europe, anyway. Probably isn't worth the trouble. I just wish we had more brake options here.

How did the r1 work out? Anyone install 330mm rotors? I'm wondering if it help braking performance.

Glad you're happy, but did you notice any improved braking performance? How about initial bite...braking power? Lower dust? I'm need new fronts ASAP and I want to do front and back at the same time. Currently considering Brembo low metallic and thought about giving the 330mm front kit a try, but another Metris friend of mine has the R1 kit on his and I will reach out to see what he says also. Thanks for the feedback.

Brembo has a 330mm kit here in the NA. Brembo 4196714KIT Mercedes Brakes Kit – Pads & Rotors Front and Rear (330mm/300mm) (Low-Met) – Brembo 4196714KIT Brembo 4196714KIT

I replaced my original brakes with Padig pads and Zimmermann rotors and overall I felt they were equal to or ever so slightly less to the OE. This time around I'd like to get something close to the same or better, BUT will less brake dust. I've probably narrowed it down to this Brembo kit or the R1 concepts.
