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.
