The tires I showed on my nomad with the Chevelle rotors were shown with a 3 inch suspension drop from stock which is what a lot of guys do (2" dropped spindles and 1" lowering springs) which is also about what you get with the stock suspension compressed close to the a-arm bumper. If you look closely you can see the all-thread used to pull it down to that ride height which I was trying to simulate.
That CAN happen with a stock suspension too. Try doing that and turning with those disc brakes and the tires will rub. The picture from the front shows the tire position very clearly. If you set the car up sky high in front and the fender never drops below the top of the tires on turns those misfit rotors will work fine.
But most guys nowadays who got past the 60s drop their cars at least 2" in front. Not sure why anyone would use that junk when there are much better options available.
