How are they Turning Stubs

[NAYRBNYLF]

Our cars with turned stubs, wheel baseIs measured from the center line ofThe ball joint

[Confused?]

Wheelbase should be measured center of hub to center of hub. Going to the ball joints can give a false reading, esp. if they car has a large amount of caster.

My car has the rearend squared off of the frame, where the 4-link brackets are. I only check the LS wheelbase to make sure it is legal and not under 108"

I have seen many posts about measuring wheelbases on many different threads. I was taught a system, in the mid 90's, by a racecar engineer /fabricator. You can use it to measure wheelbase, chassis pick up points, rearend and engine setback, basically any pickup point on any chassis. It is a valuable tool for chassis tuning and I have seen it used for chassis repair inc front/rear clip replacement. The tools needed costs less than $50 and you probly have most of them. It usually takes 2-3 hrs depending on what ur checking.

My question is this! What would you be willing to pay to be taught this system? Im not trying to rob anyone as Im thinking the price point to be around $99. PM me your thoughts on this......thanks

Thanks for the reply guys I think with some help I got it and answered some of my own questions on reference points. I do care about wheel base but that alone won't tell you how much your stub is turned because of caster. Since these are fixed lowers though you should be able to extend your midplate line and measure to your outer lower pivot point to see the difference. Also note your "installed" wheelbase. Its just a place to start. I don't have a tech in the class this will be in so I can do a few things to accomplish what I'm after thanks fellas!

In trying to find various measuring points on a chassis, you have to find the true centerline. That is one of the benefits in the measuring system in my above post.

May be a stupid question but I am curious. What is the benefit in turning the stub/ leading right front?
