Brake Reaction Rod Help

[CTX-SLPR]

Long before stuff was available we use to use screw in balljoints. The threads were 1/2" x 20 threads. So you can run a 1/2" thread coupler or tube adapter into a 5/8" tube and run a heim plate on the lower control arm. I can't remember the part number of the ball joint but it was threaded halfway down the shaft. (2")



Weld this sleeve into the frame section were the factory bushing sat. http://pitstopusa.com/i-19425222-how...-screw-in.html

How well did that hold up? I've long thought about that and even asked Pro Forged about doing it and they wouldn't even give me the engineering specs to consider out of liability concerns. A ball joint is more likely to be able to fit the existing frame bracket and it certainly makes clearance easier in that area without a 9/16in threaded end sticking out in the same basic space that my intercooler tubing and lower radiator hose run. Thanks for the real world validation of that idea. I'm guessing running a top tier Howe joint is the best idea.

On my other line of though of using spherical bearings New Hampshire Ball Bearing is one of the few places I've seen listing axial loading limits on their spherical bearings. My math model for sizing these things is each bearing can take 1.5G of deceleration with the 4200lb car on the listed limit strength (which gives me a factor of 2 safety since limit load will deform the race). That's an axial limit strength of ~6300lbs. The 0.625in bore Beryllium-Copper units have the highest axial load rating I've seen for a direct application though they are metal on metal. I'd have to step up to a 0.75in bore unit for the sealed units to get the factor though it's close at 6130lbs for the 0.625in unit.
