Uneven lowered height

[JohnL]

You could take out the rubber spring cushions in the rear struts, give you roughly a 1cm drop, at the possible expense of a slight increase in harshness.

Personally I quite like the look of a slightly lower front than rear ride height, and in theory having the rear a little higher creates a tad more weight transfer at the rear reducing understeer a weeny bit. Also in theory it reduces lift, to a tiny degree at speeds you shouldn't be driving at!
