Voodoo13 Solid Subframe Conversion Bushings Nissan 240sx 89-94 S13 Voodoo13 adjustable aluminum subframe conversion bushings allow you to bolt in a S14/S15 subframe into your S13. They are designed to rid subframe to chassis play by eliminating the soft OEM rubber bushings. Solid subframe bushings are a sure way to reduce unwanted wheel hop as well as maintaining set suspension geometry. Unlike the competition, our subframe bushings feature a unique deep angle chamfer in the center to lessen the difficulty of the subframe re-installation to the chassis. Instead of re-using the rear factory finishing caps like other companies, Voodoo 13 provides our own finishing caps to add to the aesthetics to an otherwise bland part of the car. The front subframe mounts use a beveled ring to utilize the factory subframe braces. Slide-in shims allow quick subframe adjustment without removal, to either raise or lower the mounting points. Lowering the subframe will decrease anti-squat while simultaneously increasing the roll-couple, while raising the subframe will correct roll center on a lowered car while increasing anti-squat.
