I was at the YasDrag strip today , and i must say that PP performance.ae have done a great job with their mods on the m5. i ran my M5 (bone stock on Semi Slicks) several times , with Toyo r888 315/30 20" and the best i got for the day was 12.1 (slip available).
I've been to the last 2 Drag Race events , and the best ive seen the PP performance M5 do was a 11.474 (as seen in the slip above).
Best of luck on your next tunes/mods on the beast .. hope the M5 Manages to get 11 flat or under. *thumbs up for pp performance*
