What air pressures did you use (Sat Morning? Sat final?, Sun Morning? Sun Final?) What changes were made as the track tightened up?

Thanks,

Mike

Friday morning we started around 16 lbs. and then took about a lb. out for each session after that.

Saturday and Sunday morning we used 12 lbs in the right rear, 12.5 RF, 13 LF, 12.5 LR and in all of the finals we used 8.5 right rear, 9 RF, 9.5 LF, 9 LR.

All we did with the RX30 was remove 1.5 degrees caster for Friday and then added .5 back to it for the rubber on Saturday and Sunday.

For the other karts we ran an F axle with standard hubs to start the weekend and switched to a short M with short hubs to help free the kart up over the rubber. We ran with 1.5 degrees caster in all weekend and the same front track width all weekend.
