I ran the QA1 upper and lower on my car before switching to rack and pinion front end. They worked good and although aren’t adjustable, still provided more positive caster than stock control arms. Magnum force makes a control arm that you can adjust without taking the eccentric bolt out and winding the rod end in or out. If you’re going to spend the money, those are the ones I would get. However, the QA1 are a good upgrade from stock.
