S2000 Convoy

[LunarOne]

Saw a long convoy of S2000s in various states of mod cruising clockwise around J14/15 of the M25 last Sunday. Quite fun to see, but some of them had their wheels fitted at what looked like a 30 degree camber angle. I won't pretend I've never seen it before, but doesn't it absolutely wreck the car's handling, let alone the tyres? I was driving so couldn't get a photo.
