Quay 4 link, with or without anti-roll?
My 3rd gen Camaro Lamplighter project is equipped with an Ed Quay, unequal length, four-link system, and rear frame. It is a back half build the OE front suspension and Randy Mans front struts.
The question, up to recently adding an anti-roll rear bar, has been the standard thinking. However, there has been some suggestion that the unequal length bars work better without the anti-roll. For those racing with the Ed Quay back half, what is your feedback about the anti-roll bar?

Re: Quay 4 link, with or without anti-roll?
My Monte was built by Ed in 1985 and my experience was the opposite. It was an unequal 4 link. I struggled to get car from not rolling over. With anti bar it solved roll over, but cant say it was faster.

My car is a Quay car and I had an anti-roll installed to stop the body from rolling so bad. I have had zero issues with mine.

Re: Quay 4 link, with or without anti-roll?
Do you have access to scales?
My first GT car was a Quay car. I was able to correct that tendency w/o a anti-roll system with more preload in the right top bar and a little extra height (3/4") on the driver side front spring. That being said - there's nothing wrong with an anti-roll system. Also - downward (nose down) rake on both bars (top and bottom) helps to limit the amount of roll.

Larry this may seem crazy to you but it really helped mine. Once I got to 5.60s it was a hand full. Just an option to keep in mind.

Curtis, I like that, a good idea and easily done. Do you also employ an anti-roll bar?

Re: Quay 4 link, with or without anti-roll?
I have built two of these cars and have not had problems with body roll, not sure if it is how they were setup or lack of power, lol.
I worked with Ed 20 years ago and he provided details on the setup that are still in my car today. My car is setup neutral- no squat and no separation. I have some preload in top passenger bar but minimal. Bottom bar is 2 degrees down, cannot remember top bar location. I scale car with 40# more on driver rear than passenger rear. Front is same side to side. I did have driver front springs 1/2 coil higher initially but went to Santuff springs which are equal. Never saw a difference in roll. In my humble opinion- if the shocks are set soft, rear springs are soft or 4 link is set for excessive squat- you could have the body roll. It appears some cars require anti roll bar and some do not, everybody has a different recipe. |
