How hard is it to adjust the camber on the C7 Stingray Z51? I want to go to -2 degrees Camber prior to a track day. Can I leave the stock toe setting or does that
need to be adjusted as well?

Road Course planned is Harris Hill Raceway near Austin Texas.

Appreciate the help. Thanks!

 

If you change camber you will need to reset toe.
The camber and toe adjustments are relatively easy provided you have access to alignment equipment.
The C7 also has an adjustment for "caster" in the rear. That helps keep the rear toe curve in spec.

You really want to have someone that is familiar with aligning these cars do it or help guide you through the process.

The local Chevy dealer has a "Corvette Specialist" that oversees these track settings. Since the toe will need to be set also, I'll have them do it! Thanks!

 

Some dealerships still do not understand about rear caster and will not measure it or adjust it properly. This is a long standing issue that has been around since the C7 was first delivered to Customers. Most dealers don't purchase the equipment to measure rear caster and will try to avoid doing it since it can be time consuming. Talk to the experienced mechanic to see if he knows about rear caster and why it should be adjusted.

The reason is that as the camber is adjusted caster changes. On previous generation cars such as the C5 and C6 there was no way to compensate for the caster change when rear camber was adjusted. However, with the C7 GM provided 4 adjustment points for the rear suspension (just like the front). The mechanic is supposed to adjust camber while ensuring rear caster is as close to zero as possible. GM puts a plus or minus 0.8 degree tolerance on it. When set right with rear camber at -2 and rear caster at 0 the rear toe links provide sufficient toe adjustment, however, if caster isn't set right then they may not be long enough to get a good toe setting.

Don't believe anybody that says the alignment machine will measure rear caster. They can't. The mechanic needs an angle gauge adapter that plugs into the inside of the knuckle underneath the car. Once the adapter is installed, an angle gauge is mounted to it and the mechanic reads the gauge to see how much caster they have. Depending on which tools are used the dealer cost for the tools can range from about $250 to $1250.

GM has published a TSB that tells dealer mechanics how to properly do the adjustment. This is the number of the document: #16-NA-056.

I am attaching a pdf file of the document.

Bill: This is exactly what I was looking for. Clearly, Chevy put some thought into the handling of the C7 which is WHY I bought one. I'll be asking the "Corvette Specialist" at my dealer to introduce me to the
Alignment guy so I can get him to confirm he will adhere to this bulletin!

Thank you VERY much.
