This guide is originally for dtr1 so these changes may not work perfectly in dtr2.

Toe In (Degrees) Front

Definition: A measure of the angle of the wheels when the steering wheel is set to straight. Or, where the wheels are really pointing when you're driving straight. 

I came up with my understanding of this setting based on a setup guide I read somewhere on the net. The guide was written by someone who had never actually set up a car in DTR, and was based on his experience with real cars. As such, I can't be sure that what I do with the setting is correct. To be quite honest, I haven't really played with this setting a whole lot.

The main reason for adjusting this setting is to affect the cornering ability of the car. Slight negative front toes (both tires pointing out just a hair) serve to make the car a little more responsive going into the corners. The downside is they also reduce top speed because your skidding the tires down the straights. Higher numbers (lower values) will make the car turn into the corners a quicker and help a little in getting rid of a push. Acceptable range is 0.0 to -0.4 with left and right being equal.

There is one other thing you can do with front toes which I haven't actually tried. If you were to set one toe negative and the other positive you could in effect introduce a left or right pull in the car. This could be useful on tracks like Wakeeny where you're turning all the time, or on the "D" shaped tracks where you've got a long sweeping curve. Like I said though, I've never actually tried this. If you'd like to, to introduce a pull to the left, set the LF toe to negative and the RF toe to positive, just the opposite for a pull to the right.

Toe In (Degrees) Rear

Definition: Same as above after omitting all steering references.

All information about this setting is taken from personal experience.

Rear toes dictate how the car is going to handle coming out of the corners. In effect, what you're doing by setting these to anything other than 0.0 is causing the rear-end of the car to pull one way or the other under power. You can use this pull to correct for the rear-end being too loose coming out of the corner. The downside is decreased top speed due to the fact the rear wheels are pulling somewhere other than forward when going down the straights. As such, for maximum straight-line acceleration, you want these numbers to be as close to 0 as possible. However, I've found that 0.0 is never the correct setting. A little bit of pull to the left on the rear-end (right on the front end, or a right turn) almost always improves lap times. To get that pull, you set the LR toe to a negative value, and the RR toe to a positive value. As a general rule, I never go below .4 (number, not value) and I keep the numbers same on Left and Right sides (ie -0.4 0.4). Those are the values I use when starting a new setup.

 Once I start testing the new setup, I can usually tell immediately if I need to go higher on the rear toes. The easiest way to tell this is if you find yourself turning right coming off the corners in order to keep the ass-end from coming around. Any time you find that condition, increasing the rear toes will help. Keep in mind however that small changes in the numbers make huge changes in the handling! I usually go from .4 to 1.0, see if that takes care of the problem, then start fine tuning either up or down as needed. If you go too high with the numbers, you will introduce a right hand pull going down the straights. If you are having to keep nudging the car left on the straights, decrease rear toes.

Another affect of rear toes is to assist in guiding the car onto the straights. What I have found is that once I get the ass-end under control coming off the corners, minor adjustments in the rear toes will affect where the car wants to point coming off the corner and onto the straights. On some tracks, in order to get the best lap times, you absolutely HAVE to get all the way out to the wall on the straights (34 for example). The trick is getting smoothly and quickly out to the wall without actually hitting the wall. If you get the rear toes too high, you will find that your car wants to go towards the wall too quickly and usually slam right into it. I'd say this is where I spend the majority of my tweaking time, fine tuning the rear toes to get just the right amount of pull to put me out close to the wall in just the right spot.

The exact number to set these to is totally dependant on how you drive your car. Specifically, just how much you are turning the wheel in the corners and just when you get back on the throttle. What I have found is that these parameters change almost every time I set down to play the game. So, with the exception of a couple of tracks, I will usually tweak the rear toes a little each night after the first race at any given track. This setting is also one of the first ones to look at when attempting to fine tune a downloaded setup.
