I posted this over on the turbo board but maybe someone here can offer some thoughts. . . . Hello, I'm new here. I am looking to modify my 86 240 wagon (autotranny) for improved load capacity and ground clearance. I would imagine that this is probably just about the exact opposite of what most performance enthusiasts on this board would want but I figure maybe someone will have some advice. My current set of IPD overload springs don't seem to allow me to carry much in the way of loading over the rough roads that I currently travel on a regular basis. My thoughts for modification include larger diameter wheels with an
increased profile tires maybe adding an inch and half or so to the ride (tire radius) height. This would be followed with the installation of some (probably
custom) stiffer and perhaps taller springs that would the have effect of raising the car a bit more, especially at the rear. Anyone have a suggestion on sourcing such springs (donated from other vechicles?) or a custom manufacturer? Of
course I realize that increasing the rolling diameter of the tires will effectively raise my finaldrive ratio and I would probably want to counteract this with some mods. I figure I will have made my effective "final drive" a bit over 10% taller so what are my best options for counteracting this. This would be a swap and or mod of/to the rear differential right? What about the speedo? Am I asking for trouble? Thanks for any ideas.
