As usual with the M4 GT4, avoid ABS intervention on turn in (brake early, trailbrake, be careful with the downshifts) and rotate the car with the throttle to combat its natural understeer balance.

Find the track limits in the two chicanes and abuse them as much as you can, there's a lot of time in there.

You can use the Q setup for race sessions as well just by adding fuel, balance will be good.
