i usually run the four bar but the other night i tried the z link option on rr...i didn't change anything else except the length a little to keep birdcage level and ran the bar as far down as possible (dw8)didn't check the degree yet i'm guessing about 5 down....i went in the corner and about lost it, the z link made it really loose on entry...any other adjustments need to be made when switching to z link on rr or just watch my entry on the driving part and maybe run a little straighter....also it's not a swing arm z link, i'm just running a four and then flopping the top bar back on thr right,,,,thanks for any input..

Make sure you have equal angles front and rear bars, if not you gain rollsteer on the rr. Did the same thing with mine, just about looped it also! Equal angles, and it felt much better. Good luck!

Raising the upper bar on the RR when you are set up for Z link will tighten you up going in. I have the same setup and it has worked for me.

Yeah, that's right, jakestevens. Dirtracr, try that first. Then if you feel you need more bite off, equal angles on both bars will help without affecting entry.

I wouldn't worry about what the car is feeling like in the middle of the corner until you get the loose in condition corrected. It's likely that the loose in condition is causing your drifty feeling.

Bar angles have more effect during mid-corner through exit than on entry due to the fact that the attitude of the car is fairly level and rollsteer isn't a big issue until the car begins to roll over. Therefore I wouldn't be changing bar angles to fix an entry problem.

Put your 4/z bar angles back to where you had them. Put a stiffer LF spring on (50lbs more). Get rid of some leftside weight. Move your fuel cell to the right. Move your battery to the rightside of the car, and move any lead you might have to the rightside.

If you have a brake floater rod on the right rear put some angle in it.
