You don't "need" em... Speed Tech performance makes some amazing high quality arms, but they are setup for coils. Nothing a bag cup won't change in the lower arm though. Downside? A hair over $1000 for a full set of uppers and lowers. Beautifully made pieces though, I have a set in my Astro van.
They have billet balljoint caps on the uppers, stainless steel machined cross shafts, delrin/aluminum bushings, billet steering stop brackets, spherical bearing lower swaybar mounts, fully greaseable.
Rustic Racing also makes arms, and while cheaper, it shows.
