Should your z-link be squared with your chasis or can it have some angle to it? What I'm trying to ask, should your z-link come straight back from your bracket? What can this hurt or help? Thanks for any information you can give me. Car is tight coming off the corners. Car has 4-link on lr.

YES! Especially if it is a swing arm type Z-link.Straight and square.

The spring on the rr is on the rear end housing and this is causing us to move the bird cage to the right more and this causes the forward and rear links to be angled to their brackets, do you think this is a problem?

I would try to run the bars as straight as you can or maybe just a little toe in(1/2" or so) at the front. Angle in the bars can affect rear steer althoug very slightly on a z link.

if your good going in but tight off, lower lr spring. or lower angle of a lr bar. or add angle to the rr trailing arm(the rearward one) going downhill to back.

He has been able to pull most cars out of the turn once it stops going toward the wall. Do most drivers of a 4-link, z-link drive it hard into the turn or do they let it roll in without using the brakes or is this a drivers preference? The car rear drops pretty good when he gets off the gas. This might be upsetting the car. Thanks for any ideas.

you want to roll out of the gas and roll onto the brake. alot of guys just jump ofthe gas jump on the brake and throw it hard. this just really breaks traction. smooth is the key with a 4 bar z car. also as far as when to brake and turn depends on track conditions, and driver style. but in all tracks and styles you should be smooth on and off the gas/and same for brake.

I was worried about the same thing but we just recently had to move our Z Link brackets in towards the frame and it added angle. We didnt notice absolutely no difference! I was straight on the Top Rear and moved the bracked in 2 inches, so we added alot of angle.

Hope this helps....

Thanks so much for yalls replys, that means we can look for other causes. They lowered the top lr link, but it didn't help problem, but they didn't shorten the link, so that might have move the lr backwards and maybe the rear end is not square anymore, reading other posts maybe this helped cause the tight off problem. What do yall think?
