I'm tired of dragging parts, and have decided to get a little extra height in the rear. Tracking down a set of rear springs (I have front coilovers) is proving to be a PITA. How much height will poly isos add over the stock rubber isos?
Depends on how worn your stock rubber iso's are. Poly iso's will usually add 1/4" for each iso (top&bottom) when compared to no iso's at all. But like Tarball said I would think something like 1/4".
I had the same problem. I wanted more height in the rear, bc of rubbing my fenders, even with rolled fenders. I have steedas waiting to be put in in the rear. I didnt think Poly Isos would give me enough height.
