after a quick search nothing has popped up that would help me so here goes

after measuring the height of my old front shocks to my lowered ones to my soon to be fitted collies,

how do i work out the exact ride height prior to fitting or do i just adjust once fitted to get the desired ride height?
im looking for -60mm on the front then -65mm on the rear for the summer but -40 for the winter

its taken me ages to get the rears to be adjustable again and im unsure on what height i have them at but they are all currently matching in height after meticulous measuring and adjusting

You won't be able to measure before fitting due to differences in spring weights - just fit them, then measure the height all round and make sure they're even per axle

You want the car to have some "rake" - basically the car should point slightly downward at the front. Without the rake, not only will the car have less negative pressure under the rear, but the castor angle of the front wheels will be wrong, and you'll suffer when cornering!
