I just spotted this, yellow and red RB4, what on earth is going on here, this shouldnt be possible normally, should it?

Yep that is possible alot of people do it here is a set for it

keep spinning in 1st gear full lock until your tyres begin to wear and lose grip then change to 2nd gear then wait until tyres are flat and change up to 5th through the gears and keep your foot flat on the accellerator and there you go your spinning
