Thumbs up toe-in and toe-out

what are the effects of adding more toe-out to your buggy other than the steering beeing more smooth and controlled?

Your car may tend to wander in rhythms or rough parts of the track. Not as stable going straight.

Front toe-in will make the car more controllable entering turns, and front toe-out will make the car more controllable on exit and improves handing during the transition in an S-curve.

Rear toe deals pretty much with the overall stability of the car. More toe-in will keep it pointed in a straight line down the straightaways, and less toe-in (or even going toe-out, which I've commonly seen with monster trucks) will make the car more squirrely on the straights but it'll be easier to get the back end to come around entering a turn.

So rule of thumb: toe-in=more stable, toe-out=more sensitive; front toe deals with cornering, rear toe deals with straightaways.

Not necessarily but for the most part you have it right, but to add a little more,

Toe in the front, will make your car more stable in the straights and easier to align for jumping purposes. This will make the steering less sensitive and allow you to have more turn in the middle of the turn out.
I find this to be better suited for larger tracks.

Toe out in the front, will allow for easier turn in and will also make corrections during a slide easier. To me it is ALWAYS faster to have toe out.
You can play with rear shock angles to get the car to turn better middle out if you have toe out.

In the rear, It is best to have toe in, this not only does what OTE_TheMissile states but it increases rear grip
I wouldn't go higher than 4 toe in the rear or lower than 2 degrees.

For buggies, typically it is best for -.05 toe out to -2 toe out. Camber -1 to -2 in the front. +0.5 to -1.5 in the rear depending on track. The rear toe is generally a stock preset that can not be changed without getting alternate arm mounts.

Pack a lunch, but I think that this is an amazing amount of information of what different changes will do to your car.

I don't know if it's better, but it's a very good read, and easier to understand, perhaps. I wouldn't consider that quite as in-depth, but then again, some people don't like in-depth, they want meat and potatoes and nothing more.

How about this? Read both and you'll have a better understanding of the subject matter.

you have to learn the basics first

P.s have you even clicked the pages within the text of my article? it explains the gist of everything very well.
you must not have clicked on them, has way more information than your link my friend

has answers to the following questions: each of which has pages of information.

How Camber affects handling.

How Toe-in and Toe-out affects your handling.

How Sway Bars affect your Handling and Performance.

How different Shock Angles change handling and performance.

How Spring Weight and Spring Preload affects handling.

What Shock Damping is and how changing it can affect performance.

How changing Ride Height can affect handling.

What is Droop and how it affects handling.

What is Ackerman Steering and how does it affect handling.

Yes, I did take a peek through it, it's good, and has more information about other aspects besides geometry changes/handling. Motors, batteries, etc. Just about every handling aspect that you listed there is discussed in EXTREME detail in what I linked. With plenty of illustrations, and less ebay banners.

Both are very good. And people can read both, agreed?

Yeah, it's pretty scientific, allright. I can only handle about an hour of it at a time, any more, and my eyes start to glaze over.

Man, I just wish I had these articles in the 80's. It would have beat the heck out of the trial and (and lots of) error methods that I used to try to get my cars right back then.

i have a b3 and a b4 but I'm talking about my b4.. it tends to turn too sharply and the rear spins around with the front so i can often end up facing sideways

sorry for the late response

But i dont't think that information really matters now since to be honest i think this thread has come to its conclusion, unless anyone has some facts not been pointed out before.
