3 heats and tried a few things out....full spikes heat 1 were to grippy and kept rolling....so mini spikes for heat 2, brand new on the front and old ones on the back and the car kept losing the back end...found some decent mini spikes for the rear in my box and heat 3 had one of the best runs ever to qualify on pole for the 'B' final with an 18 lapper.....shame i arsed the final up......
