I'm not sure what happens to the suspension under cornering on the Golf. The mini handles much better better with a 1.5 - 3 deg of negative camber on the front wheels. Effectively giving you maximum tyre to tarmac contact on the outside wheel of a corner and increasing grip. This is great except you loose tyre to tarmac contact on the straights so it's a kind of trade off. Proper racers will alter the camber depending on whether it's a twist circuit or one with lots of straights.
I have tried giving the Golf some negative camber on the front to see if it handles better, but due to not being able to set it up properly I've just worn the insides of my tyres badly. Didn't seem to make a huge amount of difference but I haven't tracked it yet and to be fair the level of grip on a proper circuit is 100 times better than the public roads so I'd never be able to figure out if it is an improvement.
Ooops sorry for the long thread, can you tell I'm bored at work?
