Toe-In / Toe-Out

What is Toe-In / Toe-Out?

Toe-In / Toe-Out describes the angle of the front (or rear) tires when viewed from above. If the front of the tires angles in (or towards the chassis), that is Toe-In. If the front of the tires angles out (or away from the chassis), that is Toe-Out.

How do you change Toe-In / Toe-Out?

Toe-In/Toe-Out can be adjusted to increase or decrease steering and steering response. You adjust Toe-In / Toe-Out by turning the turnbuckles attached to the steering knuckles.

Front: Adding Toe-In will decrease steering into a corner, but add steering out of a corner during acceleration. Toe-In will also stabilize the car under acceleration. Toe-Out will increase steering into a corner, but cause the car to wander a little on the straights and in bumpy sections. It is not normally suggested that you use more than 1° of Toe-In or Toe-Out.

Rear: On the rear, more Toe-In results in less on-power steering and slightly more entering a corner. Less Toe-In results in more on-power steering and slightly less entering a corner. Less Toe-In will also increase straightaway speed, as the rear tires will scrub less.

On the rear, there will always be Toe-In or 0deg of Toe. You will never use Toe-Out in the rear. On most cars, a Toe Block designates the degree of Toe, while others have turnbuckles to adjust (similar to the front). To change rear Toe, either adjust the turnbuckles or remove the Toe block and replace with another block. To change rear Toe on the TC3 (kit uses 3° of rear Toe), remove the rear block (R+3+2) and replace with the R+2+2 block. This will change rear Toe-In to 2°.

There is a way to give the TC3 0° of rear Toe-In. Take an extra F block (it's the block that holds the REAR of the front inner hinge pins and put it in place of the R block (the one that holds the FRONT of the rear inner hinge pins). Placing the R+2+2 block (or R+2+0 block) will give you very close to 0° of rear Toe-In. This will make the car much faster in the straights, but alot more twitchy and harder to drive.
