Wheel fitment offsets etc

[shifty]

Looking at some rims there 18 X 9.75 et20 I want to keep it same front and back for the concave .
I have coilovers but no fender roll will these work and if so whats a good tyre size.

Fine on the rear, doubtful on the front, they\'ll stick out too far.

There\'s a post about offsets etc here http://www.mazdarotaryclub.com/forums/forumdisplay.php?f=19

and another very recent post about almost the same width/offset here:

yeah was afraid of that they only do et20 I can get 8.75 front but I lose the concave which is what I like

arch rollers are quite cheap now bud...seen them on ebay for £80 ..... but never done it myself....cheaper than a new of wheels.....may be worth doing some research on a local bodyshop that can do it for you....they heat the paint so its flexible and gently flatten the lip .....suspect no guarantee though....

worth researching
