Hi Mark, nice work on the brakes.
A little heads up on the sway bar, the original Mr2 one is fine for the standard 1.8 car, but a slightly stiffer one will help with handling and body roll. It's just one of those little 'tech tips' the down side is pot holes and rough roads really attack the car when a stiffer sway bar is used.
I've got and Audi a8 front sway bar on the front and a 19mm hex bar on the back (due to the 4.2v8 weight) it's not road tested, but around the track the car has hardly any body roll. I think I've got a couple of youtube vids showing the rear swaybar construction and the obvious track vid where you can see how flat it is around the bends.
Kudos on the attention to detail
