Rapom's Rocket - just another Duster build thread

Question for you 72Blu: Trying to figure out if my stock upper A arms are going to become an issue when trying to fit wide 17 or 18 inch rims up front. Nearly everyone I see with these on an A body is also running adjustable A arms. Besides the wider range of adjustment are they also solving clearance issues? Do you have any info you'd care to share??????

Yes, they do also solve clearance issues if you get the right type. The "V" shaped tubular UCA's are narrower than even the stock UCA's. I originally intended to run my Duster with stock UCA's and offset bushings. In fact, I WAS running it that way until I added my 18x9's and 275's. But because of the offset on the 18x9's, the rims actually hit the UCA's before full steering lock at full suspension droop. It wasn't a huge amount of interference, but they hit. The tubular UCA's clear.

How much of a problem is that? Hard to say. The chances of being at full suspension droop and full steering lock at the same time are probably pretty slim. But I didn't want to chance it. It also depends on the front rims. With a set of 18x8's I doubt it would come up. Even with 18x9's with an offset to run a 255 in the front it probably wouldn't be an issue if you set the offset so the tires were out closer to the fenders than the frame. But with the offset I needed to cram a set of 275's in there it can become an issue. Another one of those annoying wheel clearance things, it depends pretty much entirely on the specs and design of the rims you want to run.
