Whats wrong with 0 degrees of front toe?
Most are run with negative front toe and sometimes toe-in.
So whats the disadvantage of 0 degree front toe? Or does it have any advantage at all? |

toe in gives you better straight line handeling but you loose turn in, toe out gives you better turn in but you lose straight line handeling, but 0 deg is not bad

Ok, thanks for the inputs. Ill just set my front toe angle to 0 degrees since
I mostly run on straights. |
What you have to remember is that the toe changes while driving, and 0 degrees of toe when measured statically typically results into a small amount of toe out while moving forward.

Actually I think it can fluctuate more than that (i.e. from toe-in to -out). Depending on whether the car is on or off power, the toe can be out, in or anywhere in between. To check what your range of toe is, you need to have a setup board, take a reading with the wheels pulled back (by hand; radio on just to make sure they stay put) as far as play/slop will allow it, then pull the wheels (again by hand) the other way and take another reading. If your range is narrower than 2 degrees of toe you're doing very well in my books. I am usually aiming for a play of +/- 1 degree out/in, so theoretically I would have zero under "normal" conditions. |
Nothing wrong with 0 toe.
Everyone has very accurately described the different affects of toe. But you really need to try it for yourself. Front toe drastically changes the way your car drives. Run your car with with all different settings. You will see the differences for yourself and make your own decision on what you like best. --pakk |
Years ago, I ran with a little front toe-in. Under acceleration, the wheel align itself to 0 degree of toe because of the slop. But I dont like how it looks like
with the body installed. Recently I tried a little front toe-out, the steering is sharper but kinda sensitive to road surface irregularities, a small road dip sends my car a little off the line. Tonight I will try +/- 1 degree out/in. Thanks Niznai. Any advice on how to do toe adjustment without a setup station? Im just using a steel ruler and new wheels and a calliper. |

It seems however that you have an unacceptable problem with bump steer (i.e. toe angle changes associated with suspension travel). Adjust to make sure this does not happen anymore (shims/washers under/on top of steering links either at steering block end or steering link end). Check on setup station. After this try again on track and there should be no more issue with bumps unsettling the steering. Without setup station is very very fiddly and unreliable. I used in the past a couple of long stainless steel rulers attached to setup wheels (you know, the aluminium skinny wheels) and measured the distance between these at the front and at the back at a set distance from the hub, but you don't get degrees, you get milimetres. You can convert between the two, but you need to be careful as errors do propagate. ask some nice soul at the track to let you use their setup station and it should take you the better part of five minutes. Make sure your steering throw is equal left to right and the steering is centered with the servo at zero trim, and nice arm to link angles (depending on the car these may not be 90 degrees). All this stuff takes longer to explain than to do on a station. Good luck. |
Thanks for the advice but Im still saving up for a set up station.
Can I use alignment wheels instead? Regarding bumpsteer, how will I know if I how much shim to add? Should the steering links stay 100% horizontal after shimming? Any baseline guide? |

I think I get what you mean. The front of the wheel should have the same
distance as the rear to get 0 degrees. Regarding bumpsteer, If I shim it on full suspension travel, wont it be misaligned again when settles? |
You get used to the feel of the car and how you prefer it in time I would say.
For example, front toe out on a very high bite track can be too aggressive for some, and in some cases you could even grip roll if you tried to carry too much speed into a corner and the front of the car was too soft. As said, it is all about trial and error, and what suits you best :) |
