I'm thinking about lowering my 91 Rex and I would love to scrape the floor but Potholes and stuff dont make that to resonable. I already have Tokico 5 way struts and springsand Im running stock 15in rims on stock tires 205 60 15 eventualy to be slicks 205 50 15.. Am I better off getting the ground controll coilover sleves or just getting lowering springs and if i get the coilover sleves will that work with the springs I have or do I have to change them too. This will be used for auttocrossing .....thanks
