well my car is set up for track use
ie bilstein tarmac front suspension , bilstien gravel rears so it basically pretty hard and it isn't much good for 1/4 mile
i have still managed a 13.003 @ 116 @ pod (standard rd tyres)
I have also done a 12.87 @ 109mph @ avon park (standard rd tyres)
it has full trim/interior as the road car and it's 2wd 350bhp @ flywheel
4wd with this power are alot quicker they will do about 12.4's / 12.6 's if launched right
