I read here somewhere that the Z06 factory alignment is biased for track driving and will wear the inside front tires in normal street driving. If that is the case can I just overinflate the fronts to 32-33 psi to compensate for this wear pattern ?

Sorry, I dont have an answer for you, but I'm interested in what some of the more informed folks have to say...

My 08 came with an aggresive alignment for street driving and did wear the inside of the tires. If you're not tracking the car and want even tire wear, go with approx -.8 degrees of camber in front and -.6 degrees in the back. That is what I did and it works for me.

I don't think so. The inner tread wear is caused by negative camber, top of wheel leans into car.

Guys that track their cars with street alignment and tires, sometimes over inflate their tires to keep the edge from rolling under on tight turns.

There are posts on this for making the car more "Street" friendly. (Taking some of the Negative Camber out). This will cost you if you like to use it of fast curvy roads.

I think the factory alignment your thinking about has to do with Z51 equipped cars....I don't think it was Z06's....I could be wrong though. I base what I've said by factory tour and what Tadge J said at Sebring awhile back (GM invested nearly 1million to update equipment at the factory BG to get better specs)....I used to have a Z51 equipped Vette and when I looked into it I don't remember Z06 being issue.....

but like I said, I could be wrong....maybe someone has more info than I....

Base and Z51 have -0.45 deg camber as the nominal setting. Z06s have -1.0 deg camber as the nominal setting. Agree with 2k Cobra, if your driving is not of the aggressive/track variety and tire life is really important, take out some of the negative camber. Also make sure that the toe setting is correct. Lots of negative camber with excessive toe will wear out the fronts.

davidfarmer

The -1deg isn't enough to destroy your tires, and is much less than performance German cars come with, but if you aren't concerned with handling, then set the front and rear camber to zero and move on. Keep the front too within 0.1deg OUT to zero, and keep the rear 0.3deg IN to zero. Excessive toe can destroy tires faster than a degree of camber.

It's funny... I took my Grandsport over to a friend who works on lots of high end cars to get the wheels balanced. I noticed that after about 10k miles of daily driving, both the fronts and rears are very worn on the inner portion of the tires.

This thread definitely answers my questions as to why. It's too bad there isn't a factory option for street or track setup. I'm probably going to have to get new rubber soon.

acrace

The option is a user-based option . . . it is the amount of adjustability designed into the vehicle. To me that is one of the stellar attributes of both the C5 and the C6 . . . the ability to play with camber, caster, toe, rake, ride height, corner weights, so that the owner can more closely optimize the car to how they use it.

I just had my Z06 aligned and I went with -0.9* on front camber with 0.08* total toe[out]
On the rear I went with -0.6* camber and -0.02* total toe[in]

Interested as I am ready for an alignment.

Ok guys, you got my attention, I'm getting new rubber this week, replacing stock gy with ? and was going to have alignment checked. I dont think the stock gy wore poorly 13K some minor outside cupping on front, both sides. I don't want to change the factory set up just make sure its right. What should I tell the guy? Street only, aggressive.

Here's the recommendations from PFADT depending on what you plan on using the car for.

BTW, many have found the factory alignments to be all over the place and factory settings are quite aggressive for track use. The car was developed with the track in mind so an aggressive alignment makes sense.

If you want your tires to last and don't plan on tracking the car then tone it down with the help of these specs...

This forum is the best. Thank you.

Gentlemen,

Just my $0.02....

Both my Z-51 '07 Vert and my current ride, an '09 modded Z06 were "twitchy" initially...plus I learned the hard way re uneven tire wear ...as other folks have written in this series of posts.

What solved this issue for me, was having both vehicles set with Stock C-6 alignment parameters...resulting in better tracking, elimination of "twitchiness" and even tire wear. Downside was handling on real curvy roads wasn't as sharp. (This minor malady, by the way, was eliminated when I had Pfadt adustable Coilovers installed and car had alignment checked...again.)

Hope this helps.

Regards,

Bob Duffy

I'm not a great mechanic but I've been doing my own alignments for years. David Farmer posted above in this thread and go to his webpage and he has a DIY guide. I follow a different homemade method than he illustrates but they both work.

Advantage of DIY is no appointment necessary, save $$, + you know what u have and u can make adjustments for a track day w/out standing in line at the tire service place. If u see that your tires are wearing funny part way through their tread life then take a couple of hours and make an adjustment to correct. Just because it's a "homemade" alignment does not mean that it is not accurate.

Dive in. The water is fine.

I've been doing my own in my own garage for years.

What abouts is the cost for an alignment?

mark1107

Pep Boys does a four wheel alignment for $45.00 No one can beat that. Unless your guy who does it himself in the garage!

mrwrenchphd

And I suppose you also opp for the $6 hair cut as well?
