Just curious, I got Eibachs put on 3 weeks ago and I'm wondering how long I'll have to wait for them to settle--especially the fronts. Rear is fine, but front is higher than I thought it would be. If I decide to replace just the front with H&Rs, can you help me? And is it OK or not to mix springs? Will it screw up handling since I wouldn't have a "matched set"? Thanks for the info.
