Reply to "Front A arms"

Mike,

DeTomaso did it for the Si and Performance Automotive Technology (http://www.patsauto.com/) did it for their Si clone. I've seen photos of Si front control arms next to standard Pantera front control arms and the good news is, the extra 4" in length is all outside of the sway bar and shock mounts. If you wanted to fab' a set of longer front control arms, the way DeTomaso did it, the only other modifications required would be tie rod end extensions and longer brake flexible hoses. You might also need stiffer front springs and a stiffer front sway bar to compensate for the increased leverage of the longer control arms. Also, while you're fab'ing new front control arms, you'd want to move the upper ball joint rearward and lower ball joint forward, for increased caster. If I recall, the Si front wheels had +56mm offset vs the 15" x 8" Campi's 19mm. The Si also has one of the upper control arm chassis mounts higher than the other, in order to put some anti-dive geometry into the front suspension.
