Barracuda Ride Height?

I have RMS front suspension and rear leaf springs. I set my front height first then did a -1 inch drop leafs from factory settings. Your drive shaft length should be the same for wherever you set it. If you have the street links rear you will be able to adjust your height front and back for whatever driving style you want. I would say start at front and adjust the back. It will travel up and down if you understand what I’m saying. What size rims are those 18s or 19s. For the Fastback to look really good in my opinion it’s better to have the wheel well full with tire.
