Ride height is better measured from centre of wheel
Strange. They've worked well for me.

Is it? Whats the best ride height for coilovered CSL's?
Not the most accurate way of getting a reading as shim says. Even a variation in tyre pressure would throw it out but by the sounds of it you wanted a rough height to check yours against.

Reason being rears are not matching is due to car being corner weighted. If focusing on this then this obviously involves adjusting the spring perches to get balanced diagonal weight onto each corner, therefore affecting ride height , resulting in it varying.
Overall ride height I requested a drop circa 20mm iirc.

If your ride height is varying by that much, corner weighted or not, then something is not right. The ride height itself is just as important as the corner weight and both need to be good but not completely at the expense of the other.

I've witnessed many times corner weights being performed incorrectly, the surface not being properly flat, spring platforms being all over the place etc. When a car is correctly set up for weight, corner weight, spring platforms, ride heights they always come out pretty symetrical.

Aesthetic reasons, practicality or track use its down to preference really and what its to be used for. Is if for mainly track?

Standard is around 600mm +/- 10mm with around 5mm more on the front.

Tbh pooky these were the measurements I made with the car in the driveway having not been moved for some time so not an ideal situation for giving any form of accuracy but a rough guild of height for toby to work from.

Bottom of rim to top of wheel arch is standard form and a better way of measuring ride height but still not 100% accurate. Bodywork could even be out marginally.
When I had my car corner weighted there was a slight variation with rear iirc and you will often see varying slightly, its normal. Sometimes this can even be because the car manufacturers chassis jigs allow a certain amount of tolerance, this means every chassis is slightly different. Combine this with the fact that many cars aren’t balanced to begin with because of fuel tank position, driver and passenger weights etc. and you can sometimes have ride heights different by several millimetres.

In my case as you pointed out Im more than certain this is most probably down to suspension bind where it hasn't been moved for a while and on entry to parking also playing a role.

I'll roll the car and take another measurement this afternoon to give a better and more accurate reading.
