Yes, you'd need the wheel hubs/bearings, as well as struts and/or trailing arms, and almost all the piping. IMO, it'd be easier to learn to threshhold brake!
I can't speak to the prices on bearings/hubs over there in the UK.
As for the trailing arms, yes, trailing arms are only on the rear. Just look at one with ABS and see how the sensor mounts, then compare it to one that doesn't have the mount.
I agree with Shawn on this one, as I almost always do. Way more work than benifit in my opinion. Practice maximum braking in an open/deserted area, these cars have amazing brakes from the factory.
