My buddy designed a tri-4 link for my car.. custom deal.. very similar to what the mustangs have... Tons of fox body rustangs running around in the 8's with this same set up.. we put the coil overs behind the axles. We would have love to run them straight up but room was a limiting factor so we angled them slightly towards the center. They are attached to a welded cross bar that run fame to frame... on the front we did some thing similar to the RMS set up but we ran them from inside out... it imperative that the angle be perfect on these top bars in order to keep the rear from side to side movement.. the top bars are mounted to another cross bar mounted from frame to fame.. I used Hiem joints on everything.. I guess we will see what she does next wk...lol
