Brake booster is a no no for left foot braking, with the commodore brakes on front and camira vented on the back it is easy enough, and with mechanical adjustment on the pedal box and hydraulic tap on the handbrake you have a huge ammount of adjustment.

i am actualy going to move the pod, and seal it in a box and move the radiator and oil cooler, get some positively charged air, there is not that much of a vacume in that area, but the hole over the extractors/intake seems to work well enough.
