just for the sake of discussion and because i love your replies.....i really learn a lot.......
of those who have run both........which did you like better and why a 4 link on both sides or a 4 link lr and z link rr

differences in feel and handling ?

differences in the way you drive the car ?

so......what...........nobody has an opinion ??? how often does that happen ???

i personally have drivenm 3 link and 4-z but never full 4 bar car.

i like the z link because you can adjust in and out of loose , tight , rear steer or be neutral, it think it lacks bite but i am learning all the time.
thats just my uneducated experience.........but what do i know? thats why i asked for others opinions.

ran the z link last year and this year 4 link. Too soon to tell for sure but seems like the 4 link is easier to drive or at least thats what the driver tells me. WE also changed from LR clamped to spring behind so Im not sure its all in the RR that hes feeling. What he has told me is that with the z link he had to hit the corner right and pick up the gas right to make it work, sometimes it would come right around the corner other times it wouldnt. With the 4 link he said you can get on the gas and it is more consistent lap after lap. But like I said its still early to tell yet.

I think the z link as typically setup will tighten a car up. But to me most anything you can do with a zlink you can do with a 4 link as well, just have to get bar angles right. One thing I see different is the indexing if you have the spring on the front of thecage on the RR. With the bar angles set up both ways for minimum rear steer then I feel you will get more indexing with the 4 link which will load your spring more and may tighten in and loosen the car off more so than the z link.

We plan to try z link again just to see if there is a big difference, but right I know we are concentrating ont he 4 link.

I think it revolves around tires, a Z-link to me has less side bite. On an IMCA G60 i notice most stray away from a Z-link, because it has less side bite than a Hoosier.

Thats the reason i believe the Pierce cars run real well in a UMP type enviorment.

4-Link the same thing, to much for Hoosiers, we had to run some wild bar angles to get the car to steer and not push everywhere due to the ample side bite of the Hoosier tire.

Thats my story anyway.
