I recently had the opportunity to run against these "fast" cars. I no longer think they are "fast". I know being at 5500ft elevation helps a lot, but the margin of victory against the RS4 & SLK55 was so great that I rather not disclose for fear of being ridiculed.
The 63 was a closer race, but I could still give him the hit & run him down with ease. Modded 335's really rule at altitude.
