I need to get thr front spot on to take measurements for the shocks for my rather bespoke rear suspension. (BMW semi trailing arms)

Get the front as low as you can Sam so that you have about 4" clearance to your Sump / Bell housing giving you just enough clearance for humps. Then set your rear slightly higher.

The lower you can get the car to sit the lower CofG and less roll in the car, may even generate a bit of ground effect downforce but then someone would need to come up with a rear diffuser to fit the chassis (kick up the but) to get the most out of it. When on track days i'll drop the car by an inch or so and it does make a noticeably flatter ride.
