It is similar in concept to the RennTech kit but I used 5/8" aerospace rodends (stronger and higher quality), steel tubing with swedged ends (std. NASCAR components), and designed my own high misalignment bushings to take the 5/8" rodends down to 12mm so I wouldn't have to drill out the subframe mounting points. All parts are either stainless or plated to prevent corrosion. All parts cost approx. $2000 (mostly in rod ends). E-mail me if you want to discuss further.
