tubular upper control arms.

With heims?- Hotchkis.

But why do you want heims? I've run them on the street, they do not last. They're low mileage, race car only parts in my opinion.

If adjustable UCA's what you're looking for, Bergman Auto Craft sells adjustable SPC tubular arms with delrin bushings. They're adjustable on the car, have a wide range of adjustability, and the delrin bushings are the best thing out there for a high performance street car in my opinion. The SPC arms are overkill for most folks, but I think they're the best UCA available for these cars.
