None of the above with a 3.6 CWP !
T5 is ok with 3.9 and a 610 profile tyre, just ! But you now have a 640 proflie so 4.1 is looking better !
the rest are not close enough ratios to keep the engine on song around a track , if you have some dosh try the Elite ( tractive,selholm,Drenth ), it has final drive Drop gears which you can play with to save changing diff ratios .
Or buy one of my dog boxes and gear it to suit your car
