I mean if I'm going round a corner normally (won't be in 1st gear, ever) Planting my foot won't light up a back wheel, the car will generally understeer if i'm going too fast (found out OFF a public road, please note). However, when I had 4 'arrowspeed' tyres on, it was more than happy to step the tail out if the throttle use was too liberal, enough times to really pish me off aswell.
If I where to dive into a corner, brake late and turn sharply with the throttle down, I'm sure I'd end up oversteering tho
