I currently have my set up on a 4bar lr and z-link rr. I am wanting to change it up some, and have decided to go to a 4 bar lr and 3 link rr. The rr will be locked down (non floated) with the spring on top of the rear end. I am wondering what would be the best thing to do with the lr. Do I have to lock it down also, or would it be better to leave it floated? What would be the pro's and con's of both? What kind of difference should I expect? I am thinking it should loosen the chassis up some, because I have a very bad push with the 4bar/zlink. Please all opinions and advice are appreciated.

By clamping the LR spring your going to increase bite coming off the turn (tighten it up) I run a 4LR-3RR setup with the LR floated on the birdcage. Pro's and Con's..............

Pro: more LR bite, looser entry
Con: more LR bite, looser entry

I guess you just have to decide if you can use more bite coming up off the turn??? Also if your tight now then maybe it will help you going in, b/c its gonna loosen it up. But as soon as you touch that throttle you better have it pointed in the right direction, b/c she's gonna pick up and leave. Sometimes that can be scary!!!

It would be real nice to know what springs you have and stuff. That could be your whole problem

I ran my 4-z left rear behind as a 4-3 link on a short dry-slick 1/4 mile.I just locked the rr birdcage took the top link off and left my spring on the swing-arm with no spring rate change,it really felt like it freed the car up on entry and though the middle and exited real well.I liked it like that and going to try it at my home track with the new car.

Not sure who did it. The car was picked up from a guy in Texas. I think it was updated in 2002.
