    Posting results and pics of a recent install of UMI Stage 2.5 suspension kit and Wilwood disc brake upgrade on my 1970 Camaro. Work was done by The Hot Rod Shop in Troy, MI. Original handling and braking was fine but this is a serious improvement. Viking adjustable shocks are a nice touch and I have adjusted them twice and quite a difference from comfortable street setting to rock hard race setting.

    Beautiful car and great info with the pics and write-up. 2 things: I think u posted the wheel stud bolt pattern instead of the back spacing. Also, can you measure your height from center of wheel to bottom of fender lip? Gives us a better idea of actual suspension height not affected by tire/wheel diameter. Ok... things...how much wider you think u can go with the front wheel/ tire?

    Thanks biker. I corrected the bolt pattern description. I will take a look into the suspension height measurement.
