run a 12.2? It must be your track/elevation/conditions or something. Here we have to have a dead perfect run to hit 12.2 in a stage 5 Z. At least for me (haven't even hit that yet).
Then again most stock vipers were running 13.3 at 110 today at the track, so maybe that's a sign that all cars are slowed down here. Either that or the drivers suck here.
