No roll bar. At ATCO they didn't seem to care at Englishtown they didn't say anything because we were in the elimination rounds I was running 11.5 for my time trials and got lower as the day went on, but my 60 was still at 1.7. Maybe some of the Jersey NY and PA people can chime in. Is ATCO a faster track then ETown? My 60 at the few time runs I made at ATCO were in the 1.6 range around 1.7 at Englishtown. I guess my weight made my ETs better then my 60 looked. MPH ranged from 118.5 to 121.5 at both places. Keep in mind, many of my runs were with little, to some, to extreme tire spin. 5800 shifts and around 6000 RPM going through the traps.
