you want "adjustable ride height" LCA's, Like CCM's or maximum motorsports. They allow for ride height adjustments to compensate for slicks, lowering springs, tire and wheel size, etc...

I think it depends on what you want to do really. Different applications will call for different bushing configurations. I agree with Mach1, the adjustable ride height LCAs will offer you much more versatility whether you're looking to hook-up straight line or carve some corners...

If you're into drag racing only, I'd save the money on more expensive bushing consifurations and just get a set that uses polyurethane in both ends.

I heard that polyeurithane (sp?) can get too harsh when in both ends of a LCA. It can cause binding and other problems.

Exactly right. If you want a Drag Only car that see's very little street driving, then you're OK with poly's at both ends. It when you're taking turns at speed that you induce bind. So if you're only going in a straight line, the LCA's don't want to move side-to-side, and therefore, bind is not induced- here you're ok with polys in both ends.

If you plan on doing a bit of street driving with the car, then the poly's will become a problem at both ends. In that case you want to start looking at some different (more expensive) designs that allow more free articulation at the rear of the car. Those that have multi-piece polyurethane at one or both ends where the outter edges of the bushing are softer than the core (e.g. Steeda, Maximum Motorsports, Etc.)... bascially for street driving or autocrossing you're gonna want a bushing design that DOES allow side to side movement of the LCAs...

Oh yeah... in addition, if you plan on doing any street driving, you don't want poly's in the UCAs at all- for the same reasons you don't want them in the LCAs but more-so because the UCAs sit at opposing angles.

Hope that helps.

I have polys in both ends of my lower control arms and drive it on the street all the time, with no adverse affects at all. I believe this to be the case with thousands of other stangers out there, and im suprized to hear this opinion of polys.

It just makes it more responsive, less slop, and handles better. No bind. Maybe inexperienced weekend mechanics are overtightening the bushings and causing thier own problems?
