For the first time in 30 over years, the IRS on the Z31 and S12 is no longer an archaic monstrosity to be ashamed of!
Replacing the bushings ends of the trailing arms with sturdy rodends and adjustment hardware, this kit will allow you to correct your camber fully, correct your toe fully, eliminate the sloppy eccentric bolts that like to seize, and eliminates any possible binding from bushings.
This is not to be confused with merely slotting the subframe, which by it's very nature will not correct camber enough on most lowered cars, and in extreme cases will cause excessive uncorrectable toe. This recipe has been used for years, and has eaten many tires doing so, some people have refused to acknowledge how bad this is, others have accepted it as the price to pay. This no longer has to be the case.
You can have camber and toe within factory specification, even lowered beyond driveable.
The total cost of installing this kit should not exceed $250, and requires no modification to the chassis, the subframe or any other part except the trailing arms.
