Well,, kinda said news,,I was cruising around this evening and this black car pulls up next to me and starts down shifting, like three times at least, then takes off,, newer M6, so next time he gets next to me we go I pull three cars on him then slow down... the next time he comes he make sure his rpms are up and in his power band before he gets next to me,, then we go again,, my car down shift as I'm cruising at 1100 rpms, and he walks me, and I was breaking the tires loose at above sixty...so I call it one for one,, mind you I just hit 300 miles tonight...There will be other days, and better tires..
