wilwood disc brake ?????

Money, as in cost, is very subjective and relative.

I've used Wilwood brakes on many vehicles, my own and customers. I have never had any issues with them. Willwood is very clear about what size wheels are required for each brake kit and again, i've never see clearance issues if these requirements are followed.

Unfortunately folks don't read small print, auto parts stores often aren't as knowledgeable as they could be, and once delivered, often instructions aren't refered to, untill something doesn't fit.
They saved and sweated getting them, only to find the desired wheels don't fit, and they don't have the money for new wheels and tires, - - - subjective, relative, - to you maybe, - try to tell that to the spouse, rent due, - car on blocks .
Then they come in on a hook, and we go from there .
I certainly can't explain why folks are like they are, but have found myself guilty occasionally, how bout you ?
Ikea maybe, lol
