I know this has been brought up many of times but can not find it. What should the alignment be set at? Have appointment next week.. Thank you

PatternDayTrader

Depends on what your going to do with the car.
A street only car will drive best, and get the best tire wear with about one tenth of one degree (.1) positive camber, and zero toe in. Set castor to whatever the factory spec is unless there's a pull for some reason.

Street only

whitec7

Is that for the rear also?

PatternDayTrader

Well there ya go then.
The alignment debate always seems to center itself around the camber spec.
It seems these cars are set up at the factory with more of a track spec for camber.
Don't buy into that nonsense if you are not going to the track. Go with a tenth of a degree positive camber and live happily ever after.
Ive done hundreds of alignments over the years and that's why I'm qualified to speak on this issue.

PatternDayTrader

Zero to a tenth positive is perfect for the rear also.

Thank you very much

You'll get a lot of different answers here.

For best handling performance, the settings posted below are the preferred settings, and they are within factory specs. The primary difference is that the factory specs specify a broad range for each parameter, within which the car is considered "in spec." The DSC settings below are precise.

The other thing to keep in mind is that rear caster settings are very important for predictable handling, and many dealers don't have the tool, and/or don't know how to adjust rear caster. A performance alignment shop is usually the best bet.

If max tire longevity is your main goal, and you're doing mainly straight-line highway mileage, you'd probably want to dial back on the camber. However, even in street driving one can benefit and enjoy best handling. I know I do. I live in an area with a lot of twisty rural roads, and my car is really dialed in on the "street/occasional track" specs published below. I carve the twisties almost every day on my way to and from work.

Make sure you take the car in with no less than one half tank of fuel in it, close to full is better.

I don't know if the Base car is setup any different than a Z51.
Regardless of what setting someone wants, the Factory alignments can be hit or miss as far as being properly aligned.
When I had my Z51 alignment checked I wanted it set to DSC specs for Street/Occasional Track.
When the tire shop checked it, it was already set that way from the Factory.
It was not dead on, but was surprised it was close enough it didn't need adjustment.
And after 14000 miles I don't see any noticeable tire wear.
YMMV

whitec7

Ok, thanks

Foosh

Dif is correct.

Alignments are done quickly at the factory, and often are not very precise. For a Z51/GS/Z06, the factory alignment should be close to the DSC Street/Occasion Track spec, IF it was done correctly.

When I stand behind mine, looks like the back tires are leaning in.

PatternDayTrader

That's negative camber your seeing, and while this entire subject is sort of a matter of personal preference, street cars don't really do very well with a negative camber setting.

Cars has only 40 miles and is a GS, don't the tires to wear.. Thank you for the info

Alignment is important. It is also very important to be an OCD about maintaining proper tire pressure too. But even more important is to keep those 30 second burnouts under wraps.

PatternDayTrader

You are absolutely right with the idea of getting this done before the tires wear funny. I would put 1500 miles on it first, then take it in.

I had mine('17 Z51) done at 700 miles.I could tell it wasn't "square".

It was within specs....but the specs are very wide.

As Foosh said,The DSC street specs are right-on.The dealer charged me $89.Well worth it,IMO.

I disagree.

As I said above, it depends upon how you use the car. If most of your driving is in a straight line, you can go back to more neutral camber, because you won't be needing or using the best handling package.

However, if you enjoy a lot of twisty road driving, you'll be missing out on superior handling. About half my daily commute is twisty roads, and the other half city/highway. The OEM PSS tires on my '14 were showing perfectly even wear when recently traded at 15K miles (all street), and it was set early on to the DSC Street/Occasional Track specs @ -1.2º front camber.
