For best performance (low CoG and least drag) the roof height should be adjusted to be just over 120mm from the ground, with the car on a 10mm block, which is as low as the BRCA rules allow you to go.
You then trim the shell so that it doesn't catch on the floor. You can get pretty close by pitching and rolling the car on the workbench, although I always end up trimming a touch more off at the track, but it's best to start on the safe side and not cut more off than necessary.
