I'm tempted to try Mad Russians's free & easer camber adjustment. ( http://m3.madrussian.net/diy_camber.shtml ) I gather from some posts on the forum that this can provide at least -1.7 degree camber, and also that -1.7 is fine on the street and is better than stock on the track. What I'm still confused about after doing some searches is the toe setting. Several people suggest that if you have anywhere near -2 camber, you need to change the toe setting, and toe settings are suggested - but different ones, ranging from 0 to 0.13, and I've no idea why.

Can anyone provide any insight into what toe settings could make sense with somewhere between -1.5 and -2 negative camber, and what the relevant plusses and minuses are? (Also, anyone know the stock setting?)

Finally, while I think it would be great for everyone, myself included, to know the plusses and minuses of different settings, I might as well ask for what makes the most sense for my car & how I drive it too. If it makes any difference, I usually use stock size tires on 18" wheels, but on track, and sometimes there and back, I use 265/35 18 Toyo's all round. I sometimes drive on the autobahn, so high speed instability is not a plus, particularly when windy and/or wet. But of course, I hate understeer and like tossable handling ... I'd like to find the best compromise setting for every kind of driving, but I am also open to swiching settings from time to time, perhaps one for driving to, from, and on the track, and another normal street setting. Perhaps a summer and a winter setting (winter = 225/45R18s all round).

I did this free mod and noticed a tiny bit of difference in steering feel but nothing major. The car still has quite a bit of understeer with both stock 18's and 19's and stock suspension.

I did not have the car re-aligned after this mod and have not noticed any odd tire wear after 10k miles.

Essentially, the easiest way to think of it is that slight toe-in increases straight line stability at high speeds, whereas slight toe-out increases your turn-in (makes it easier to take corners). The problem I know of with that, at least with mustangs, is that increased toe-out increases the ackerman issue already inherent in the stock suspension geometry. Since the BMW folks don't base their stock geometry on the '78 Ford Granada, I assume we don't have this issue. Hope this clarifies somewhat.

That definitely does help, thanks! Though do you (or anyone else) by chance know the stock toe setting?

The Fox and SN95 Mustang chassis (based on the '78 Fairmont) actually lack Ackerman, which is where the inside wheel turns a tighter circle than the outside, which would be ideal for obvious reasons. All modern cars have excellent Acherman and is easily seen with the naked eye.

[CMendez]

^That was actually my point. Due to the lack of ackerman, the outside tire gets dragged through turns and causes horrible tire wear at track days. That being said, I think you're right about the fairmont. My bad.

I was actually going to start a post asking the same question. Thank you zimmt for posting it and to all for the information.

So I don't need alignment done after doing the madrussian guide? Sounds good to me. What is the "tiny bit difference" in feel do you mean? Please elaborate. TIA.

Exactamundo! Well said

Sorry, but I mis-read your topic line. That's what I get for reading it too fast. This isn't really what I was hoping for.
