I took the studs out of 04 F7 EXT at the end of last season. I wanted a lighter rotating mass and better turning so I bought the double stud backer plate and installed two studs every third location in place of two studs each section. I centered the first followed by a pair one quarter inch further to right of center and then one quarter inch left of center and went back to centered. I started torquing them down when I thought "heat exchangers". I know the supply and return, if you will, run on the outer limits of the running boards and meet at the back. I'm concerned about the section of tunnel that dips down right down the middle. It looks like my studs that are centered would land on either side of the section of tunnel that dips down, but the one set to either side look like the could hit if I bottomed out. Any thoughts?
