Cheapest way to drop the rear is to swap the overload leafs onto the top of the spring pack, that will drop it around 40mm. Fronts, lower coils for you budget, I would get some half decent shocks if you can stretch the budget.
There's a fella on AFF with a supercharged FG XR. He's done some custom "true flame" from the front bumper over the bonnet and quarters. Looks mint, will look for the pics.
Probably tripping because when you measure a 10" rim it's actually 11" wide edge to edge, your probably not taking the bead seat into account which is roughly 1/2" either side.
