RXBG is talking about ride comfort and luxury equipment that the R8 has that the CSL does not. Having a mid-engine configuration and only 2 seats does not change that. Considering the compromises of the past CSL I think it would be fair to assume future CSL's to be lacking in creature comforts. The M3 CSL's time is amazing regardless, especially considering when it was conceived. Would R-Compound tires on the R8 show considerable time improvement with AWD?
