There are indeed TTs that do fit the 4 piston calipers,they're just not cheap or easy to find. If you note on the blue car above, the TTs spokes have an inward taper just before they meet the outer rim, not much but maybe 3/8" or so. These also fit the C2 vettes and that's why they're so hard to find. I've got a set on my '66 vette and have been offered $1500 for the set........ain't selling them!
