I haven't dove into redoing my suspension yet, but from the reserch I've done and some of the threads I've read, I'm still not up to speed as to the issues behind the LCA bushings. From what I've read, it seems that the poly buhsings allow for too much movement of the LCA, but the OEM type rubber bushings do just fine. I'm not looking to start another poly Vs. rubber debate here, as I already prefer poly over rubber (I won't say one's better than the other, but it just falls to personal preference with me). I'm just curious as to what exactly the deal is with the LCA bushings. Maybe this is something that'll become quite apparent to me when I get the car up on a lift to redo the suspension?

Y'know, it doesn't have to be either/or. I run rubber LCA bushings, Moog "Problem-Solver" UCA bushings, and poly strut bushings, along with the front end dropped about 2-3". Looks good, rides good, handles good. All I know is, I'd HATE to pull everything apart to replace the LCA bushings if I changed my mind. Struts, or uppers? Not that big of a deal. Just my $.02.

Do you use stock or tubular UCAs? I'm trying to find out if I'd get any benefit from tubulars on a street car or if it'd be money better spent somewhere else for me.

Stock UCA's, but if I had it to do over again, I'd use adjustable tubulars. I like the built-in geometry and extra adjustment, as opposed to the "Problem-Solver" bushings, but then I like my front end as low as I can get it.

I don't plan on lowering my front end more than 2" (if that). Looked around for Moog's "problem solver" bushings but couldn't find anything

I don't recall the year of your Duster but '73 comes to mind. The bushing you're looking for are the Moog K7103; they are listed in Summit's online catalog.

Growing older is unavoidable but growing up is strictly optional.

Close enough. 'Tis a 74

So is the issue of proper camber only prevailent when lowering the front end? And if then, how far below stock does the problem manifest itself?

Camber is a problem when lowering the front and caster is just a problem. It is made worse by raising the rear and/or lowering the front because that changes the angle of the steering axis which is basically what caster is. The factory only allowed for a couple of degrees of caster which is minimal in the first place then with wear and tear and suspension geometry changes it can be difficult to dial in enough caster to keep the car stable at highway speeds. The steering gets skittish and the car tends to wander if it doesn't have enough caster.

Interesting. According to my speedo (subject to inaccuracy since I don't know what drive gear is installed, but I've got a 3.55 rear) I've had the car at 90MPH on the highway here and it tracked straight as an arrow and the steering felt great. Makes me wonder if the suspension wore down to just the right caster geometry. It's all getting redone though! I just wish Gearhead had gotten his LCA bushing mod all finished up (and distributable).

I keep hoping, but I'm not holding my breath. The dude's busier than a one-armed paper hanger with hives.
