this result might give us a hint how C63 will perform. Somewhere between 8.05-8.09 min is my guess.

Yeah, not a good time considering how much the damn thing costs.

Does anyone know the difference between R compound tires and R-tires?

I think they're the same.

They might be used interchangeably. "R-tires" may be a shortened version for an informal term popular among roadracers and autocrossers, "DOT-R tire" (race-compound tires, generally with treadwear 40-80, approved by US Dept of Transportation for use on the street). Some might differentiate "R-tire" to specifically mean a street-legal soft-compound semi-slick (like a P Zero Corsa), while an R-compound tire with more conventional tread pattern (like P Zero the Hero) might not be considered an "R-tire." But for the most part, they're pretty much the same. Meaning they're much grippier than standard high performance summer tires, when warmed up.

With the same tires (Corsa's) the C63 will be faster, because of the shorter gear ratios. 8.00 min is possible IMO.

people said the same about M3 and R8 capable of 8.00 min. Im not that confident anymore. Im not sure M3 DCT will cope with 8.00 min either. Of course I hope Im wrong

That seems a bit odd, maybe it will do better on Hockenheim.

I presume this test was done on R-compound tires? If so, then it is a dissappointment because it just "matches" the E92 M3, which is SO MUCH CHEAPER.

If, however, this was done on standard tires, then the time is pretty good.
