Quay 4 link, with or without anti-roll?

[Dragsinger]

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?

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.

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.

I would lengthen top right rear and had 120lb additional on left front. The car was very crooked looking. My bottom bar was 3 degrees down and top bar was 17 degrees down. Once anti was in I was able to make right upper bar neutral with only free play removed.

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?
