which control arms???

[David Pozzi]

check out upper arms from Global West, Speed Tech, and Detroit Speed, they all help you set additional positive caster which helps keep the tires flat in a turn. Lower arms won't change geometry, there are some benefits of easier indexing of the coil spirng, because most have a plastic seat that can be rotated to fit your coil.- if it's cut, it will still sit in the bottom of the lower pocket.
