I am looking to do some suspension work and such, and originally was going to go all OEM, or as much as possible for my 83 Mirada - HD Torsion Bars, HD Sways, new shocks, the 11.75" Rotor upgrade - and was wondering if sourcing and refurbishing these factory parts was even worth it given that I wanted a more performance oriented ride. Poor mans pro touring if you will. Obviously the upgraded and higher priced components from the aftermarket companies will offer more performance with the upgraded specs and combinations of the bars etc, and wonder if the desire to go OEM was worth it or even as cost effective as originally thought. Any advice is appreciated. Thanks.
