Mark, seems you should use 4wd calipers if you want to use standard wheels. I have 2wd calipers fitted which are fine with 17inch Mo's but I want to run 15's for the strip and with the 15's I have acquired from a R reg escort finesse they catch the caliper. At the moment I'm thinking spacers and possibly the grinder. But just wondering if anyone knew if another type of wheel fits. I'd use steels if they fit!
