we would like to get some ideas as to the pros and cons of both if pssible.
Am I right in assuming that with the swing arm on the rr the top bar from the bird cage would go to the back of the car, which would also basically be a z also ?

Also have heard of a reverse z ? and what would be the purpose of this > As you can tell w e are new to the 4 bar stuff and are trying to do some learning before considering which to try and what brand.
Thanks

i've been trying to get a little more educated on this myself...we normally run the four bar (dw8) but a few times i ran the z link, just flopped the top bar back..i found it to be really REALLY loose on entry...ran the rr bars parallel, stiffened the rr spring but still was looser than i would like in order to drive in hard....first race out this year i'm going with the zlink on the right only with the spring put on a swing arm this time, seen a couple of guys running it like this and runnin good, i've been kickin around as to what spring to go with since it's on the arm...good luck..

Try a 250 or 275 on the rr, or check the tool box, it has a swing arm spring rate calculator to get you close to what spring you are running now.

A stiffer spring on the right rear will always free a car up more. You should have tried softing the right rear spring and that may have helped with you loose in.

As far as the Z-link goes. From what I've played with this helps control rear steer in a car. The best set-up I've seen work is a swing arm Z-link on the right rear and your two bars forward on the left rear just like it came. But every driver is different that's what makes so many different things work for so many different drivers.
