Hello,
There is a set of stock drop links in the classified section.
Would they fit a 19mm sway bar?

Or should the 19mm sway bar be purchased as a set?
If so: which set is best for street use (value and quality)?

Thanks

The appropriate size depends on more than just the use of the car. It also depends on the rest of the suspension. A car with very stiff rear springs and stock front torsion bars would want a sizeable front sway bar in order to make the roll stiffness similar on both ends.

You can adjust an adjustable bar, obviously. If you have a large bar and want a small amount of roll stiffness, you may wind up making very very small adjustments. With a softer bar, you would be making larger adjustments to get the same effect.

The stock non-adjustable bar is 15mm. The 19mm adjustable ones are often seen as a reasonable replacement when the rest of the suspension is stock. The 21mm ones are obviously stiffer and are best when paired with something like 150 lb/in rear springs or larger.

Note that adding a rear bar changes the rear roll stiffness and the desired front bar size can change there as well.

Thanks DD.
I’m considering the bar that Travis is offering (see pic above).
From what I understand, my rear springs are 180#.
