Tubular upper arms-I feel lucky tonight

When you are running meats and streamers the adjustability is pointless, your car will corner like crap anyway.

They do little or nothing even when you are running a standard wheel and tire like 14s or 15s with some BFGs.

They are however useful when you move to a real performance wheel and tire package like abodyjoe is running.

The weight savings is insignificant on all but race cars where weight reduction becomes a priority.

In the end.. If you choose tube control arms you should only buy the best quality. Often people buy crap like this simply because it looks cool.

I have to disagree with this reasoning...

Adjustable UCA's give you more caster - caster equals more straight line stability especially at high speeds. so anyone going above 45 mph will benefit from the added caster of an adjustable UCA, or as much positive caster you can get out of a stock UCA - I got 4.5 degrees out of my stockers and thats about as far as you can go.

An adjustable UCA can give you as much as 7 degrees positive caster so when you have skinney's up front and meats out back the car will want to go straight and not wander. those big and little combo's of tires are harder to control then rubber bands and you could use all the help you can get at the drag strip!
