Which Tires?
Haven't tracked the C63 yet, but I was running RE-11s on a similarly (nose)heavy Audi S4. Not bad for a street tire but the grip levels weren't anywhere near what you'd get from a proper R-comp.
I am running shaved RA1s on the P-car (they stick as good as any - Hoosiers included) but the car is easily some 700lbs lighter than the C63, has a 50/50 weight distribution and the suspension is set up for track use so it would be meaningless to draw a comparison.

I have to disagree in terms of the grip level of the bridgestones. I use a vbox every time I go to the track, and the g forces that those tires are able to pull without breaking loose are extremely close to my r888 R-compounds on my gtr, a car that's very similar in weight to my black series. The RE-11 also wears much better than the r888. Of course neither is going to be comparable to a Hoosier or dedicated track tire, but its tough to find a better street/track combo tire .

I've used the Dunlop Race on the 911 and Cayman and they're pretty good. Grip similar to the R888, decent in the wet if they have tread depth, and quiet enough on the road (unlike the R888, which howl a lot).
I found the RE11 to definitely have less grip than the R888 or Dunlop Race on the Porsches. Maybe the GT-R is able to extract more from them?
Have heard only good things about the RA1, but haven't tried them since they're not available in my sizes.
Can't comment n the gtr extracting more grip out of the re-11, as its the tire I use on the black series, and use the r888 on the gtr currently but will be switching to NT01 or Trofeo R soon.
Never tried the RA1 so I definitely can't comment on those. And those Dunlop race maxx's I'm sure are good, but damn they are expensive! $699/tire, no thanks.

I've heard the Trofeo R don't last even as long as the Dunlops, but no experience with them. Both are expensive. About $2K a set with the 911, about $250 less with the Cayman.
I've never driven on R888s before so this will be my first set, but I am buying them as dedicated track tires (I do have another set of wheels for the street with Michelin PSS). Load rating looked OK (93 for the 245 fronts) and I'm hoping there won't be too much sidewall flex, plus I won't be pushing nearly as much.
As for potential track-day "deficiencies" of the C63, I have read numerous reports of people's cars going into limp mode after only a couple of laps due to excessively high oil temperatures (especially on the MCT-equipped cars like mine), but I have not experienced this on the street even during sustained driving with manual shifts at high RPMs. Keeping fingers crossed. Will replace the brake fluid with ATE Super Blue and throw on the R888s (hopefully driving them to the track will wear off some of the mold release compound).
The Best of Mercedes & AMG
The main issue I had was the rears would contact the inside heat shield between the wheel and exhaust. Mercedes bent the shield with a block of wood in about 5 mins and it's been fine since. I'd not consider going under 275 now, but would go lower profile next time round. I'm on Nitto NT05 wheels which have impressed me.




I run stock suspension and 18 x 9"wheels with 275/35x18 tyres and no rubbing.
Will be changing my fronts to 245/40x18 from 235 when they wear out.
