front disk brake conversion kit

Rick Ehrenberg's Disc-O-Tech. Still the gold standard 35 years later. Master Power has spindles and caliper brackets, everything else is part store stuff.

DISC-O-TECH: Stop on a dime

If you insist on keeping the small-bolt-pattern wheels, you will need something less effective...Scarebird offers a kit for that.

You just gonna keep disagreeing, or do you plan on explaining yourself or supporting your opinion with data?

I’d love to see another analysis of the suspension geometry, data plots, whatever you’ve got. Bill Reilly’s info looks pretty good to me though, and it shows Ehrenberg wasn’t right about a lot of things he said. And while I’m not a fan of coilover conversions either it’s pretty clear Bill Reilly is really knowledgeable when it comes to suspension. But hey, if you’ve got more data I’d love to see it.

I’ve run 73+ A-body and FMJ spindles on the same car. I stand by what I said as far as the geometry changes being small and arguably beneficial for a car set up like mine. And the ball joint thing, well, it’s not a thing on any of my cars running FMJ spindles. I’ve checked. I’m not actually convinced Ehrenberg did check, and his complete lack of data supporting his opinions certainly doesn’t help him. He threw out a lot of speculation and not much else.

After all, the B/R and FMJ spindles were “factory engineered” too. Some of those cars even ran radials from the factory, something the A’s and E’s never did. And that changes a lot with regard to the suspension geometry needs. Why fight so hard to keep geometry that was designed to be run with bias ply tires? What works best with bias ply’s is not best for radials.
