Thread: One Way To Build A '32 Hyboy

Tweet

Here's a spur of the moment question.

Hey Ken, any thought on running anti roll bars on the front or back, or do you think the car is light enough to not warrant? I'm using a Heidts IFS/IRS and would value your opinion here.

Kitz,
Thanks for your confidence in my opinion. This is a subject that I'm an expert on.
Now this is how I do it. I always completely build the car and drive it in it's raw state. If it feels like it wants anti roll bars I put them on.
That is the only way I know how to do it. I have figured out the roll center on cars, center of gravity in relationship to the centerline of the spindles and axle, and about every other method that people have told me is the absolute way of determine this. The best way I have fond is, just the way I do it.
Sorry I'm not much help.
Ken

Ken, Part of my reason for the heavy gauge was that it will be a seat as well as a gas tank but I don't regret using the stainless for strength or corrosion resistance. With all that beautiful work I'm hoping you put a nice fifty's style nerf bar in the rear at least, just a suggestion.

What a coincidence, the same scientific approach I use!!! I conduct my "Does it need a sway bar" evaluation on this curvy road around the lake... On one particular curve, if I can come into it at 45 and have an exit speed of 55, no sway bar required..... Before I put the bar to the car, I also play around a bit with spring rates and shock valving.... If I do use a bar, I always use one with adjustable end links for adjustment...Figure if I have to carry the extra weight, might as well make it work!!!!

The nice thing about just going out and buying an IFS chassis like a TCI is you have a chance to check a box for a rear bar - the front is standard. They will just extract a few more bucks from you, with no questions asked. If I were to build my own, say with ASC rails and some carefully chosen components from 1 (800) HOT RODS, then my choices would be as you and Ken described. Regardless, I, personally, would probably still have one by the time I was done with the chassis build - I am all to aware of how adding one to a pick up truck and a heavier version to my '86 Mustang GT helped.
