Sorry, another thought on the marks on the upper arm. Those marks are for standard height? If I'm lowered about an inch, I would have to compensate for that correct? So I wouldn't use those marks??

By the way, after putting on the used arm which was installed on a stock height car, my inside tire is wearing out, which is why I'm trying to fix this. And hopefully fixing the steering wander in the ruts at the same time. I'm just not convinced the rack is shot.
