I believe Ferrodo DS2500 are good on road and track. Maybe upgrade the fluid to something like RBF600 too.
Tyres, Toyo T1Rs are good on road and are used by some on track. Michelin PS2s get a good rep too.
Loads are using Falken FK452s but not sure what they are like on track....
As for power..... get rid of some of the weight....... Maybe a plenum spacer for a little extra torque coming out of corners. Suspension so you are faster through the corners.
