The rear of the car is easy to do even without a spring compressor. It's the front you only want to do once. I went with the dot 5 and eibach's in the front (I got 1/2" drop) and still had a little rubbing while turning and backing up. You can coax the front fender liner into a slightly different shape if necessary. So I'd do the dot 5 for the front no matter what. With the dot 1's in the rear I got 1 1/2" drop. The rear is up to you. I'd keep a little rake and stay with the stock pads that are not always but usually dot 3. My front camber didn't change after the drop but the rear was at -2.5º. The Eibach's ride sweet on the street. I'm on K&W's now.
