. . .I'm coming from the world of desert racing and rock crawlers so I'm used to seeing 1.25" joints on the rear end of vehicles and I'm pretty sure that's gonna be WAY overkill for a car. Joints that large are expensive and heavy. . .I don't want to spend unnecessary money or add unnecessary weight to the vehicle, but I do want to make sure the joints are sized appropriately for the vehicle. I'm not stuck on heims either. . .I could run bushings using delrin, but I would want to make them to fit standard width bracketry (which is sized to fit a rod end with high misalignment spacers) so even if you guys don't recommend rod ends I still wouldn't mind hearing what size is being used on track cars.
Thanks for the help and suggestions!!!

I like to use Spohn del-sphere ends. Serviceable, adjustable tension and come in the popular 3/4" hardware.
They also come in a narrow version that fits most common brackets with misalignment spacers.
