Lowers plus 1/4” non adjustableThey have an adjustable length, right?
Absolutely. I wasn't implying that having the proper pinion angle isn't important. Sure it is. But it isn't what gives you better traction off the starting line. Having the correct IC location as well as a free moving front suspension, (preferably with at least 5" of upward front suspension travel) is what gets your car to hook. You'll also need to dial in some good shock settings too, and of course taller/lighter front coil springs help out a lot.
Uppers double adjustable.
All greasable delrin/urethane bushed.
Has rubber in ears on rear as per moser.
They said it’s better that way.
