Everyone is always talking about dialing out the negative camber due to tire wear.

With no consideration for tire wear .. what would be the best negative camber setup purely for handling -- front and/or rear ?

maybe like -2 f/r......something like that....depends what u want ...high speed or low speed turns..

With standard 325 spring I ran -3.5 front and -2.5 rear. I have gone to 700 lb springs and now run -3 front and -2.3 rear. Both were very good track settings. They also really wear the tires but this setup is all about handeling.

your camber settings will also depend on what tires you are using, and what those tires like to have. this factor is even more important for track use. For example, "R" tires will perform best when the correct range of negative camber is set. So, it's really hard to say that there is a perfect setting for optimal handling - with disregard for tire wear. ideally, you should really contact the tire manufacturer and ask them what range of negative camber their tires like to operate under.

Of course, the car's suspension setup will be a factor too, as was mentioned above with regards to spring rates used, etc..

If you really get into it, you can spend a lot of time and effort getting just the right setup for YOUR car and YOUR driving style with the type of tire you use. Those are the guys who will spank you in the turns and make you wonder why...

Spend time on a track - which, if you have the means, I would highly recommend doing - sign up for a Driver's Ed event! You'll be glad you did, and so will your car. Best peformance investment you can make.

I think -3 and -2 in the rear is nearly perfect for a track setup in the Z. I'm running -1.7 all around, and I'm eating up the outside of my front RA1s - definitely need another degree of camber there. In the rear, the outside of my left tire will wear a bit prematurely, but the inside is quite even.

For street use, I have no clue, but the OEM setup is pretty close to optimum. On the track, using a pyrometer to see what YOU need is required.

Just remember, lots of camber will degrade your braking.

It depends on the tires your using...

If you are using a good R-Compund tire... sometimes -3.5 / -4.5 is recomended for the front... Rear i wouldnt go more then -2 = -2.5

depending on tires of course...

If you really want to know, buy a laser temp gauge and measure the temp across the face of the tire after some lapping. The correct combination of air pressure and aligment with give you even temps across the contact patch of the tire

Validation isn't discussed too much here, here's the one I want.

the only way to tell ideal camber is to corner weight the car and start taking temp readings as mentioned above. Anything else is bench racing

Don't bother with a LASER temp gauge to take your tire temps. They will only give a surface temp. You want one with a probe that you can dig into the tire a bit below the surface to get a more accurate reading.
That is the only way to know, as others have suggested, what YOUR correct camber needs are, as well as tire pressures. Each tire manufacturer will have different needs as well.

excellent point racin - the only one worth having is the type with a probe

I agree that the laser pyrometers measuring surface temps isn't the best way, but it is easy and quick. I've had access to both this year, and the laser was MY preferred method. I got quicker readings of the temp differences, before the temp neutralized & cooled. But I could just be slow!

Plus, the laser can be used to measure a bunch of other stuff!

Generally the more negative camber the more corning force developed by the tire. For example, Kumho recommends up to 5 degrees and states that the inside edge will wear before the outside edge if you develop max corning force.

Since I am cheap, and not looking for trophies at autocross, I set it up so the wear is even when the tires are worn out.

If you wear out the inside before the outside decrease negative camber.

If you wear the outside edge before the inside, increase negative camber.

The same approach can be taken for street use, set it up so the wear is even. One will find that a track set up will require more negative camber for even wear than a street set up.
