I've done a little searching but found some wildly different numbers on suggestions for alignment.

The car will be autocrossed heavily. It has the stock suspension and stock rims. Tires will change but they will not be an R compound tire. I am looking for a recommendation for front and rear camber, caster and toe. If anybody has learned any good info please let me know. The best I have found so far is:

setup is based a LOT on personal preference and what you have seen in the linked thread is a good basis to start from. If you don't like the settings you choose, just tweak them until you find what you like. Half the challenge of motorsports is setting up the car to the driver. Testing and knowing how to compare changes and where to improve the setup are the things that makes a truly great driver.

Are these number really obtainable from a stock suspension? The quote below is referring to camber and toe. I haven't seen too much on caster. I guess I could go to the shop and tell them give me all the negitive camber and postive caster that you can, but I'd like to be a little more methodical than that. :wink:

I'd recommend staying -3.5 to -4 in the front and -1.7 to -2.4 in the rear. You can also adjust your front and rear toe; 1/16 in. front toe-out and 1/32 in. rear toe-in.

those numbers are with camber plates. With 100% stock components telling them to max out the negative camber and set the toe to whatever you desire is just about the only instruction you can give the alignment techs. Caster is not adjustable without additional mods.

Caster is not adjustable on the stock suspension. You can probably get close to –1.5 camber in front, keeping it equal side/side. Rear camber is also fixed.

On the stock suspension, unless you want to experiment with toe, I would just have them pull out as much negative camber as possible in front, keeping the sides equal.

Fair enough. I should probably know this already but, what are the stock camber settings front and rear. 0? I know mazda alignments from the factory tended to be all over the map, despite what they specified as 'stock'.

As delivered, my settings were all over the map.

The shop was able to get front camber out to –1-1/8, and “encouraged” rear camber out to –1-3/8 without undue violence. Caster was verified at 3.5/3.75. I had them zero the toe.

I can’t remember the OEM spec’s, but I would imagine toe is zero, caster is around 3.5 and camber in maybe -.5 front and –1 rear, or something along those lines.

Good information. Thanks all.

Hey man, you didn't have to change it! I was just kidding with you. If you have a picture of your own car, I can make an avatar like mine for you. Just let me know...PM me or whatever.

Good info in this thread.

I've been searching various forums on various sites and it seems like folks with camber plates are setting the front camber higher than the back. Noticeably higher. Folks without camber plates are maxing out the front camber and leaving the rear static (well, it's fixed). That brings the front and back relatively close in terms of camber...is there a negative assciated with this? Secondly, I've got (and love) a 26mm front sway bar, so how will that affect me when I max out front camber? I assume for the better but would like to hear from experienced folks on this.

As has been stated already, you will be lucky to tempt -1.5 camber in front. Shoot for it, keeping both sides the same. Most R-compound tires LOVE as much negative camber as they can get. I would not run more negative camber in the back, than in the front, however. And you can play with the toe in, especially in the rear, to help turn in. Start with 0 toe in the rear, and move in 1/8 increments towards increasing toe-out and see how you like it. You will, however, trade off straight-line stability for more instantaneous trurn in as toe-out increases.....

As has been said, it has a lot to do with personal preference. Try it and adjust as you feel suits your own driving style.
