How should I set front toe-out on a Custom Works Rocket 5.1?

Set the Rocket 5.1’s front toe to a more negative value for toe-out. The kit setting is -1°; try -1.5° first, then -2° if you want more initial steering. The car’s listed adjustment range is 0° to -3° in half-degree steps.

Adjust the front steering links evenly and check the alignment from above: the front edges of the tires should point slightly outward. Front toe-out can help the car turn in more readily, especially entering a corner, but too much can make it twitchier on the straight and increase tire scrub.

Change one step at a time and test it on track.
