Cars unlevel after fitting uprated suspension

[naffa]

I bought a s/h gmax suspension kit (springs and shocks) for my Audi b4 coupe designed to lower it by 60mm.
Its fitted but there is a slight problem. The o/s front sits way lower than the n/s front. The tyre is catching the arch, (its on 18's with 215/40's and H&R 25mm spacers). The n/s is fine as is the rear setup, just a problem with this one corner.
While doing the suspension I replaced both top mounts and the arb link bar bought from ECP on the o/s only.
Does anyone have any idea where I should start looking to solve this issue please? I cant drive the car on the way it is.

Hopefully a dumb question, but I assume the dampers don't have adjustable spring seats?

If they do, you obviously need to adjust them to give the correct ride heights... get the car corner weighted by a specialist as part of the process.

Assuming they don't, then the first step is to remove the springs and measure their free lengths and spring rates. Also measure the fully extended and compressed lengths of the damper between eyes and between spring seats (which should be the same either side, of course), just to be sure.

Spring rates can be tested by any decent suspension specialist for a few quid, or you can estimate/compare them by simply loading them with a known weight and measuring the compression. Chances are that the corner that is sitting low will either have a lower spring rate or a shorter spring than the other corner.
