ITC Rabbit suspension help

[Eric Parham]

My ITC Scirocco had 650 lb/in front springs, no front bar, 425 rear springs, Shine rear bar. That was after many iterations with fronts between 400 and 750 and rears between 250 and 500. I found that different brands of springs were off up to 10%. I ended up with Hypercoils to reduce variables. My setup was on the hairy end of loose (even with new Hoosiers), and a real handful in the wet (400 rears or some sort of adjustability was wished for when the heavens let loose), but was definitely fastest that way. I almost always ran a VWM clutch-pack LSD or a Quaife TBD. As others have mentioned, a spool or welded changes everything (have one, only ran it once -- not my preferred style).

EDIT: I also had a very stiff cage, and Shine's spherical bearings front and rear.
