I have relocated the park brake bracket to the top of the trailing arms. I have also fitted a 1/2" (per side) shorter rear spring. With this set up I've got about 1/4" clearance between the end of the spring and rim and about the same clearance between the tyre and the front area of the frame kick up.
I am using 5.25" back space rims and 275 tyres, with this it keeps the wheels inside the guards.
I could of maybe gone 285 tyres with 5.0" back space rims but the tyres would be sitting right on the fender lip.
I still need the lower the rear of the car but that will have to wait until the car is fully assembled (bumpers, interior etc).
