got a bit of a problem my fiesta rs turbo has just come out of the garage after a full rebuild of engine and repaint, bot the arches are catching the wheels ive got 195/45r16 tyres on the cosworth alloys no idea about the springs as i bought it as it is i just need about 1" inch clearance on both sides, there are a few things i could attempt puttting a bigger coil assitor on the fronts, place like a rubber bushing at the top and bottom end of the spring any other mods please help

 

Even 1" height clearance will not be any use, as with suspension compression will easily be over 1", unless springs are nearly solid.
I would just get some longer springs.
