Another thread (tall spindles & track width change... (http://www.chevelles.com/forum/ultimatebb.php?ubb=get_topic;f=7;t=007542)) mentions new spindles coming soon. They look sweet to me. 1" taller, but otherwise stock dimensions, so light weight and you keep the stock (removable and short) steering arm.

They definitely look like a product under development, not ready yet. If you like the looks of them as much as I do, give them a call or send an email (customer_service@speedtech-performance.com) to encourage them to manufacture them.

I tried to email earlier, but my email kept getting kicked back...

Are the early Camaro spindles the same as A-body?

I wonder if all other stuff (dimensions, height of wheel-centerline, ball-joint taper, etc) are the same as original? and price too!

If anybody finds out anything, please post it so we all can know...

Well, I just called and a lady answered the phone. She was very nice, but not really helpful...

She said there is no release date anticipated, and no pricing info... Of course, she also wasn't sure if it would fit the Chevelle... Maybe someone else will have better luck...

Todd is the guy to talk to.

I emailed him awhile back and it got kicked back to me, but he later responded. So I'm not sure what's up with his email system.

camaro and chevelle spindles are the same except for the steering arms.

check this thread from Team Camaro

chevelle disc brakes on camaro (http://www.camaros.net/cgi-bin/forum/ultimatebb.cgi?ubb=get_topic;f=7;t=004368)

those new spindles look nice!

So...

No steering arm? Does that mean we'll have to use our stock steering arm? If so, we'll still have bumpsteer issues.

And if there is a steering arm coming out with his product I hope Todd has plenty of experience with kinematics. Especially when it comes to a four bar linkage to design this right the first time around.

And those that don't know, there is a "tall spindle" that looks surprisingly stock on late '60's Rivieras/Clones that does feature bolt on steering arms like those used on our A/F-bodies.

What exactly causes the bumpsteer problems when using the orininal "Tall Spindle"?

Is it just the increase in camber?

Or is it the improper placement of the tie rod on the steering arm?

Is the placement of the steering arm with the tall spindle in the exact location as the stock spindle/steering arm?

What causes bumpsteer?

Bumpsteer is caused by the tie rod and steering arm not traveling in the same arc path.

I think what people are going to find out is that its not just the spindle arc path that is the problem, but the steering linkage too. Thus you'll need to redesign both to get minimal bumpsteer.

And then you'll want to discuss ackerman issues...

See why I'm concerned that someone at speedtech paid attention during kinematics class? Its not as simple as it seems.

I know what causes bumpsteer.

What I'm asking is what is causing it in THIS aplication?

If the tie rod is placed in the wrong spot via the steering arm when using a tall spindle, then we know that would part of the problem. As compared to where it is placed when using the stock spindle. If the stock spindles placement is better, then the aftermarket tall spindle would be a better option, graemlins/thumbsup.gif .

I would definitely be interested in a tall spindle that minimized the bumpsteer issue.

The bumpsteer my car has really bothers me. If I still had my original spindles, I would be very tempted to reinstall them (handles great, though).

I think the problem comes from the steering arm being to high (or low) and also too long. I have always heard that that tall spindles make the steering slower, so the arm must be longer than stock.

Well that tells me right there that the tall spindle steering arm places the tie rod in a less then ideal location, as compared to the stock steering arm.

Tall spindle using stock steering arm seems like a better swap, graemlins/thumbsup.gif .
