Quay 4 link, with or without anti-roll?

[Angelo DiTocco]

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?

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.

Bert, Thanks, I appreciate the note.

I don't need it because this acts as it's own ARB.

Larry, occasionally and I never knew when this would happen before I added the swing arm. I had made 3 passes before this straight as a string.










I haven't got to leave off the brake with it yet but here it is off the foot with the swing arm.






May not be apples to apples with a door car but I just wanted to show you what I did and why I did it.

Larry,
Put one on the car.
You can always disconnect the links if you don't need it.
My V-6 car has one and my new Quay car has one.
Better to build it in the first time, even if you don't use it was my thought.
