Thanks for the comments guys. I bought the Simmons with the intention of using them 8" front 9" rear but i think the car will sit up fairly high, even with the wheels tucked up under the archs. I am thinking along the lines of BBS RS's see pic. in 15x9 or 15x10. This is a long way away though and i will build the car to accomodate 17's.
Santa not too sure yet, but it will be delicate so as not to distort the quarter, no long seams etc. HYPO4D, i think it will stay an off-white colour.
Something along these lines
