straight stub vs turned stub

[fastmod1k]

Was wandering what the advantages and disadvantages of both are thank you!

[driver99]

The short version is the turned stub is suppose to help keep corner speeds up by allowing the car to turn more freely. I bought a car with a turned stub (didnt know it at the time) the car turned like a dream but was always horribly loose and zero forward bite. Once I adjusted the car to act like it was square it improved. Given the choice I will never buy a turned stub car again.

How did you make up for it? Did you shorten the wheel base on the r side?

[TeamGRT12x]

If you are a traction racer than a turned stub is not for you.

If you are a momentum racer then a turned stub is for you.

Very well said.

Exactly!!

If you like to throw the car in and run a ton of "wedge" or "LR" then if aint for you. If you drive it straight and keep the back end under you, you will probably like it.

Who makes these and how to identify one?

[jsf74]

Would they be better for a tacky track or dry slick track.

Put your good eye on a Pierce car the stub is turned more on them than any other that I know of.Works real well on a clamped up setup,not so well on a springbehind setup they are turned so much they like to dogtrack down the straights if you let the LR get to high.

[qrteracer]

now not to sound stupid.....what is clamped up ?

[anissa5]

I thought pierce cars where turned 3/4 i know some that are turned more then that

[jsf74]

I've been wondering the same thing? The terminology in circle track racing is a little overwhelming!

[jsf74]

I'm pretty sure the impressive cars are turned too.

[CHRISTINE]

Peirce told us a 1/2 inch lol

[anissa5]

If you measure pierce wheelbase it should be 108 leftside and 108 3/4 right side

Instead of the spring mounted on the birdcage behind the axle, it is mounted on a bracket clamped to the axle tube in front.

[jsf74]

Makes sense. Thanks.

[TeamGRT12x]

Most turned stub cars are in the neighborhood of 1 3/4" to 2". I would not call 3/4" turned. Most of the time if it is turned 3/4" that would make it almost straight up (On the chevelle stub) at least. The Chevelle from the factory was built with the RF behind the LF.

I like a little wedge , and my stub straight. :p:o

thats what I've always heard...

I can't see the speed advantage. I think If I was building a chassis for the masses. I may turn the stub to make the car more drivable for inexpieranced drivers. In the sixties they moved the right front back to get it to turn. In the eighties they moved back the left front to get it to turn. Now they are turning the stub? Educate me on this. I have built many good cars. Never did this, don't think I will. I just may be a slow learner. Show me the advantage. A day without learning, is a day wasted!

turned stub = lr behind the rf

Thats the way theyve been doing it forever to turn left.

Theres nothing to explain the inside radius of a track is smaller, your cars track width is 65 or so wide, the outide and inside footprint are two different diameter circles around the track.

[midwestmodracer]

turning the stub 1/2 to 3/4" pretty much just allows the front tires to be square with each other after caster is set. There are plenty of cars that run up front in all venues with stubs that are turned...likewise there are plenty with stubs that are 3/4" turned down to 0" turned that run up front as well.

...like a few others have said...driver preference.

[Graff Spee]

My thinking tells me that the rear of the car gets its roll out from stagger. It also has induced roll over steer in some cases. I see the front end as bieng two wheels that are not bound by stagger issues. They roll independant of each other. They do not know if they are turning or what. As long as the toe and the ackerman are working properly, how would a shorter left side of an inch or so make a change?

[missile07]

I have always been told to think of it as a steiger tractor that swivels in the center. The wheels never actually turn...one side gets shorter when a turn is needed.

Now that makes more sense to me. I may be a bit slow, but I do catch on. Thank you!

Another CRUTCH .......... All I am sayin ! ;)

Thats like say'n, running the LR clamped up is a crutch, how can it be a crutch if it works and you are fast.


With a turned stub, you run with less static toe out.
