Any question answered...

It's not that important because I usually use my legs/brake to stop anyway, I just want to be able to perform a decent skid if the day finally comes that I am DASed.

As I've already said, it is merely for show, I never want to be one of those people who skids up to every set of traffic lights.

also, are your tyres pumped up hard (100-120psi) ? can make a big difference.

Ah my tyres are rarely pumped that hard, they're really old, I've been riding on them for 2+ years and they haven't even worn down so I've not replaced them, and they can't handle anything higher than 60/70psi.
