Ant's car has a welded diff now, HE coilovers and whiteline arbs.
Trouble is it is snappy as hell, I found there just wasn't much feeling of what was going on. Whether this was due to lack of geometry/damping/rollbar/etc setup, crappy tyres I dunno. I think it might be because Ant's car is a bit laggy, and I find it hard to not drive in N/A mode (blipping the throttle, etc), but I dunno.
Just didn't feel very predictable, like I couldn't "attack" because it felt like the car wanted to bite back, probably the tyres mainly.
