I am currently in the process of converting my IRS to coil-over. Even though I’m not completely convinced that just taking out the torsion bars and installing new neoprene bushings won’t work just fine, I purchased the Eagle Products’ conversion kit. This seems to be a well designed kit and the quality is excellent. As for as the price, I think it’s reasonable considering how expensive a pair of heim joints are. Unfortunately, I was unable to use the kit because of wheel clearance problems. Therefore, I had to build my own setup where the heim joint bolts on the inside of the mounting plate, rather on the outside. I’m pretty happy with the way they turned out.
Shad, I’m curious about your comment that the one of the spring plate's function is to maintain toe. I’m not sure exactly what you meant by that. It appears to me that the adjustment for toe is through the placement of the washers on the inner pivot bolt. Also, unless you have a lot of slop in the inner bushings, you can’t substantially change toe by adjustment of the spring plate. It seems to me that you adjust the spring plate to accommodate the position of the suspension arm based on the placement of the aforementioned washers. The spring plate would then help support the arm and prevent a change in toe due to wear in the inner bushings. Is that what you meant? I’d be concerned that if you try to adjust toe with the spring plates, you could put the arm in a bind that could cause premature wear of the bushings or worse. Does this make sense? Bottom line, I think the Eagle Products’ conversion will work just fine if adjusted properly.
Also, I think Ricola explained very well why just relaxing the torsion bars does not work. That is unless of course, you’re looking for a very very stiff rear suspension.
