XJ-S Upgraded Spring Set. We'll call this spring set a "sensible upgrade" over standard springs. About 10 percent stiffer than stock, they'll shift the ride vs. handling compromise from "boulevard" toward "sport" without sacrificing comfort and will of course be a huge improvement over worn original springs. Ride height will measure about 13" to 13.5" (center cap to underside of fender lip) in the rear and 13.5" in the front (the lips are not at the same level). No two XJ-Ss seem to sit at the same height, but these springs will not significantly lower the car. Made by a large, internationally respected spring manufacturer. Car set of six springs.
