Hey guys. Just bought my first BMW Sunday. Took it out to Sonoma a few hours later, bone stock on OEM Super Sports. Boy does it need brakes! Steady 1.54/55's for the first sessions and then I blew out the right front tire. Only got in 10 laps or so but I think it'll be a good platform on which to build. I'll head back after I put brakes and real tires on it.
Sonoma Raceway
1:54:419 RPMaddict 2015 M4 DCT bone stock.
Don't have video but here's the results (33507):
