anti-squat; with approximately 0.120” (3 mm) of rear spacing the car has 0

, so every

.030” (.74 mm) of spacers is a degree less. The thin white nylon shims included in the

kit are .030”; the thicker ones are .060”.

More anti-squat (rear of pins down) will generally take away rear side bite, add forward

bite, and let the car spring more off jumps, generating a higher arc in the air. A car with

more anti-squat will ‘rotate’ easier in sharp corners. Less anti-squat (pins closer to

level) will make the car feel more stable and locked-in. Generally anti-squat is a “feel”

adjustment, changing the way the car drives more than the fastest lap. On the X – 6

Cubed it’s quick and easy to change, so have a play with it and see what you like best.

Your X – 6 Cubed also has a 2mm spacer under the hinge pin brace, which sets the

height of the rear pivot. Another way to say this is to call it the distance between the

outdrives and hinge pins. This distance affects a number of things, including the mix of

forward bite and side bite. Adjusting the hinge pin brace shim will affect anti-squat, and

your rear spacers should be adjusted accordingly. XF part # 3262 is a set of three CF

hinge pin brace shims, 1mm, 2mm, and 3mm. The 2mm shim is standard in your Kit.

REAR WHEELBASE

The wheelbase of your X – 6 Cubed can be adjusted by moving the shims on the inner

or outer rear hinge pins. As the pins are parallel to each other, moving the arm or the

hub carrier by the same amount will have the same effect.

Moving the hub carrier forward increases rear traction in two ways: Primarily you are

adding more ‘angle’ to the driveshaft, so there’s more scrub between the dog bone and

the outdrive as well as in the CVA joint. All this friction locks in the rear end and creates

traction. Moving the hub carrier forward also increases the percentage of weight on the

rear tires, further increasing bite.

Moving the hub carriers back is probably the easiest way to add steering and corner

speed to the X – 6 Cubed. It’s one of the most commonly used adjustments for Team

drivers. Moving the hub carrier or arm back some will increase steering throughout the

corner. It also makes the car more stable in bumps, and because the driveshaft isn’t as

bound up, the car will “pop” better over jumps.
