I know you should not do this but could someone tell me what would happen to the handling of a car with progress springs in the front and sportlines in the rear? I only ask because I have progress springs and although they lowered the car evenly(about 1.3in) all the way around the rear appears to sit a little higher than I would like. I wish there was a company that lowered a little more in the rear than the front. I am sure there is a reason why they do not but could someone tell me why? I assume to get the look I would really want I would need coilovers but even then if I am lowering the rear more than the front am I just setting myself up for trouble?
