[cerreta28]

Hey guys I need some help.. trying to figure out what wheel size and off set I need im going with 17s im not sure what width to go with and off set also what tire size. My kit is from west coast cobra and was made in early 90s I tried to call them but they don't pick up. Any ideas?

Put a wheel on that will fit and start measuring clearance inside, outside, on brakes and steering etc. Measure the back space and width of that wheel and tire and start doing some maths on how far you can go with any of your dimensions.
