Noticed yesterday that I can barely squeeze two fingers between the top of the rear tyres and the bodywork. I've had comments before about how low it is thinking I've purposely lowered it, which I haven't. I assume my stock springs are tired so, how high would stock Audi springs make it? Is it worth putting a different set on the back, I don't particularly want to change the front as well as there is nowt wrong with them. Comments please guys.
