It does look cheap and job-lot but that was how SAI modified them for strength in their facility then. Was not my call as I was a shimmer in my fathers eye back then.
I have seen this first hand on both original S/C and comp cars and also modified street 3000's.
I had the same thought the first time I saw this mod as its a bit shop class but seems it worked...
STD treatment for race, its true and yes this is a street car however clearly modified to race spec. Countless changes and not a conours street car.
