BEZ06

At the Rolex 24 last weekend they had a C7 chasis with no bodywork on it in the Corvette Hospitality Tent.

It was really a beautiful piece of work - the aluminum frame looked very

However, as I was looking at the rear suspension, initially I couldn't understand how they were doing the rear toe settings - I couldn't find a threaded rear toe "adjusting link" (tie-rod).

When first looking at it, I saw a rather large diameter rod behind the axle going from a knuckle on the rear of the hub support to the frame. At first it looked like it was not adjustable - but I figured there must be some way to adjust toe.

After getting down on the ground and looking back into the area where the rod met the frame, I could see that it had a cam bolt/eccentric type of adjuster with a bunch of radial lines that you can mark to indicate your current setting - just like the cam bolts for adjusting camber on the lower control arms.

So....I'm not sure why they would do that!?!?

I like the threaded tie-rod type toe adjuster, where you can really fine tune the toe with a specific number of turns of the tie-rod link.

This cam bolt type adjustment is a "try adjusting it a little and see what you get, loosen the bolt and adjust again - repeat until you get close to what you want".

With the threaded tie-rod link, I know pretty much exactly how many turns of the link are needed to adjust a certain amount.

Maybe it will be easier than I think, but I believe it's not going to be as easy to do a small precise adjustment as it is with the threaded tie-rod type link.

Oh well....I won't have to worry about until the C7 Z06 comes out anyway!!!

Ever set the toe on the rear of a 1990's or earlier 911 torsion tube car?...cam eccentrics aren't that bad...

Actually I did have a '69 911S, but I just drove the heck out of it and never bothered with the suspension.

I started messing around with setup on my BMW, but it wasn't until I got my first Vette (a 2005 C6 9 years ago) that I started doing more serious alignment work for track prep.

The Vette is very easy to work on, and I guess I'm just used to the way it's so easy to get very accurate toe adjustments with the threaded tie-rod.

When I get my C7 Z06 I guess I'll just have to learn to work with the cam bolts! Glad to hear it may not be too bad.

No question the Corvette is easier to work on...I completely agree on the threaded toe adjustments. Production line efficiencies don't translate well to DIY track alignments. Cam bolts are still better than many of the other options!

Yeah, on my C7 Z51but my dealer tech today said he couldn't get camber over stock without too much toe!! Is he wrong?

It all depends on how far the toe bar /tie rod can be adjusted.

I haven't looked at mine that closely but I would surely hope you could go to at least 2 degrees negative and have enough adjustment with the eccentrics to get the toe set back correctly...

Of course if not we can always go to these;
