It must be personal preference.
If a wheel fit my car any different, I couldn't run a 12" tire, and still not rub absolutely nowhere, both while my running clearance is 2". A mustang wheel, toyota, whatever, I will bet my car title that there's no factory wheel going to fit as good as brads. Brad made the wheels to fit, and did a fine job. Now, if you don't like his options, -there's a reason to hub swap. But, as far as finding wheels that fit the mustang pattern, good luck. Toyota, whatever, you 'probably' don't have many choices. Frogman, you probably got lucky. I bet your choices were slim to none with what would actually fit. Nothing against your wheels and swap, hey if you're happy, you're just as far ahead as I am purchasing off Brad. I guarantee your wheels don't fill space like these saleens. And again, if you're happy, that doesn't matter. But as far as fit goes, the leg work has been done, and I'm not so much of a fool not to take full advantage of it.
