sway bars rear link kits vs (lars)

[210lpa]

Hi poeples new to site ,been lurkinking for a while ,just a few q's my vs sedan its only lowered (from standard height) nothing to low , with 215/55 r17 mags the top of the rear sway bar mounts are about 1/4 of an inch from hitting the under side of the floor pan when stationary ,but when i go over rough roads it hits and makes a loud noise on the under-body of the car is there a shortened sway bay link kit to solve this problem.any advise would be helpful.also Ive had my car camber,caster toe fixed recently and is it common for the front wheels to look wider in thr track than rear on vs .my wheels are 17x*8 topforms. 215/55/R17 update today i went and purchased a nolathane rear sway bar link kit ,by the looks of it the top link bolt is shorter than my present one soit shouldnt hit .
