[QUOTE="bimmerman, post: 47948, member: 126"] Ah yes, Toe and Camber. Both are compulsory in road going cars and especially in BMW cars. I do know a little about this topic from my younger days of tuning Tamiya RC cars. So the theory would still apply on big boys toys like the E34 too. Here's a snippet of what little I know. 1. Toe: More toe-in can make your car track straighther but as a result you lose steering sensativity. Too much toe in will cause drag and tire wear on the outer side of your tire. Toe-out on the other hand will give you very quick steering response but will cause your car to wander about and wear out your tires on the inside. All road going cars have a small degree of toe-in dialed in for straight line stability while circuit going track or race cars have less toe-in or even toe-out to quicken steering response. 2. Camber: I can't explain it too well but negative camber will cause your tires to scrub less during cornering thus increasing your car's cornering ability. Negative camber will give you inner tire thread wear while positive camber will give you the opposite. So on a road going car like the E34, you'll have a small amount of toe-in and negative camber which gives a combination of straight line stability and imporved cornering grip while they cancel out one anothers inner and outer tire thread wear pattern. Like killing 2 birds with one stone and killing a perfectly good Dunlop SP9000 as well when your toe angle can no longer compensate for your negative camber. Like on my car.
