i have a 89 swb 1500, i want to lower it but i dont want to go the traditional air bag set up, i know there are the 5-6 or 5-7 drops but i was thinkin along the lines of a drop spindle with tubular upper and lower control arms, coil overs, and a 4 link in the rear with coil overs, i dont want the tub kit for the rear mainly the front is what i got questions on the rear is a no brainer. i am looking for something perfomance oriented as air ride is too much additional parts and weight. any help would be awesome. how well do the 4-6, 5-7 drop perform, i.e. ride quality, handling, bottoming out etc.
