I wasn't referring to what happens under breaking, I was talking about the electronics adjusting/compensating for loss of grip at differing corners (torque vectoring).
Anyone who would care to invalidate their manufacturer's warranty by fitting aftermarket products, in a forlorn hope of obtaining a fraction more speed or grip, is a worry to me and is completely missing the point on what an Audi is all about. Take yourself off to the Ford showroom and buy yourself an ST and go hang out with the rest of the boy racers/cruisers. An Audi is about polished refinement and functionality, coupled with performance and in the case of the S3, high residuals.
If I was looking for a race car for the road, I'd buy a race car for the road. Not buy a sports car for the road and spend £10k making it handle better. I've got better things to do with my money/time and to be quite frank, if you think you're not getting enough grip out of the S3 in standard stock trim, then you are probably driving too ****** fast for the conditions anyway.
