Depends also when you retorqued the bolts. You are not supposed to check the torques immediately after you come off the track and the wheels/hubs/etc are hot. Just FYI.Jim Itin said:I've had the Rota Slipstreams with BMW black lugs since late June. I drove about 300 miles to VIR, then re-torqued the bolts before a driving school. I re-torqued after each of four sessions, and most of the bolts did need a little tightening each time. After returning home, none of the bolts needed additional adjustment, and have not required any since then.
