Need alignment info and recommendation

so all you're talking about is straight line usage .... (and yes I have experienced this, on snow with a car with a bit of neg. camber and on summer tires) so all the tread depth measurements, all the pyrometer measurements, (on the skid pad and coming off track, and all the tires that show even wear across the entire surface of the tire are just figments of our imagination ... glad to have you straighten me out .... I guess the quicker times I turn with the "excessive" camber (and keep in mind that the tires DO wear evenly across the entire face) are also a figment of my imagination .... that is until we add toe out .. then the wear goes all to hell, and the cars become twitchy as hell

Increased caster is awesome for cornering, because it increases camber on the outside front wheel during cornering.

However, I have found that increasing caster beyond factory specs contributes GREATLY to tramlining on the street. And the S197 chassis I've been tinkering with for alignments has a very, very similar front suspension to your E46.

Yes you obviuosly have much more experince than me, guess I sould stop arguing with the idiot.

Thanks for all the recommendations. I manged to get the front caster, camber and toe where I wanted them to be. I wasn't as successful at the camber in the rear -- not able to reach the -2.0 degrees I was aiming for, and instead got -1.5 degrees.

I am not sure if "out of adjustment range" is really an "out of time to get the camber you want" or if it is simply due to the age and mileage of the car.

Front toe was really aggressive on the "old" alignment -- which would likely explain the tire wear.

Wow. Talk about a bitter old man with a head up his ass.

The why all he bold? You obviously need better reading glasses. And yes, I do know everything. I never said toe didnt effect tyre wear did I? So that was kind of pointless for you to point outlike you stumbled upon some sort of great discovery. I also never said that neg camber on the track would cause tyre wear. All I said was too much neg camber used on a car driven mainly on the street can cause inside tyre wear. Obviously this whole internet forum thing is still kinda new to you, and you need to learn how to read poorly structered and mispelled posts written from a 3 inch screen on a cell phone, while at work in between cars. I apologize for not haingthe time or patience to drop my level down to a 6 rader so you may understand.

knock it off.

We get it.

Sincerly,

The rest of us.

Yeah - this would have been a pretty useful topic.

Should we summarize and continue?

Let us:

Caster - More gives us effects similar to more static negative camber without the potential negative side effects of camber. However, it can increase steering effort and tram-lining.

Camber - Negative camber helps to keep the tires surface perpendicular to the road while under cornering loads. Increases cornering force. MAY cause increased tire wear. Can decrease straight line braking ability

Toe IN (Front) - increases stability on straight roads. Increases tire wear

Toe OUT (Front) - increases turn in grip. Increase tire wear

Toe IN (Rear) - increases stability. Increase tire wear

Toe OUT (rear) - helps turn in, helps car rotate. Increase tire wear.

Anybody care to add?

Toe out (rear) - helps car turn in and rotate by decreasing rear directional stability. Use with caution on FWD cars and use with extreme caution on AWD or RWD cars.
