Oh Yes Andy - 4.1s with both of us in the car (180kg) and standard cold tyres on, that's mega super car performance - WELL CHUFFED.
Don't tell the misses but i've just priced some R888's (soft) at £70 each, and requested a price as a dealer - tis my birthday soon. Can certainly get it down to 3.5s was loads of room left under my right foot just not enough tyre traction to cope with it.......
