Seem like 18" AMG C350 is around 1800 rpm and C350 with 17" AMG is around 2000 rpm.

Finally got out on the open highway last night and had a chance to check. Pretty well dead on at 2450 rpm. One thing I noticed for the first time is how the dials are set up, the needle actually makes it hard to read the gauge markings directly under it...guess I haven't been watching my speed very carefully...

As it turns out, the C63 has the same ratio as the C350, and has a LSD as an option. Just need to find the part # for the W204 LSD, now that would be awesome on the C300 6MT.
