JACKING UP THE CAR
The use of wheel chocks or blocks is required when ja cking up the car.
Jack stand locations are suitable for full lift and sin gle end elevated requirements.
Use care to not damage the radiator or after cooler r adiator when positioning jack.

Use rags or cardboard between the jack and the frame, as well as between the jack stands and frame,
to avoid scratching the frame’s finish.

Procedures:
1. Position the floor jack directly under the front lo wer A-arm bushing bracket.
2. Locate the jack stands on right and left sides of car directly under the longitudal tube of lower chassis.
3. Locate one of the jack stands directly under the rea r bottom cross member as far to the left side as
possible.
4. Position the floor jack directly under the rear bot tom cross member at the centerline of car.
5. Locate one of the jack stands directly under the rea r bottom cross member as far to the right side as
possible.



Never get under your vehicle when it is only supported by a jack.

PARKING BRAKE ADJUSTMENT


There are two adjustment points on your vehicle’s par king brake assembly, the parking brake actuator and th e
cable slack. Refer to the photos on the following page . To adjust the assembly:

1. Place chocks or blocks in front and in back of the fr ont wheels to prevent the car from rolling.
2. Place the parking brake handle in the forward-most position and put the car in neutral.
3. Jack up the rear of your Atom until the rear whee ls are clear of the ground.
4. Place safety stands under the car.
5. Ensure that the car is stable.
6. Make sure that there is a little slack in the cables where they exit their covers at the rear of the car near
the rear axle.
7. Take a 1/4 in. Allen wrench and turn the internal hex bolt in the center of the large end of the parking
brake application lever clockwise until the wheel cannot be turned by hand. (Track & Race package.)
8. Turn the Allen bolt counter-clockwise about 1/16 of a turn. At this point the parking brake is initialized
and the cables can be adjusted.
9. Loosen the locknut on the cable housings with a 9/16 in. wrench and screw the adjuster barrel counter-
clockwise until there is less than 1/2 in. of vertical sla ck in the cable.
10. Tighten the locknut while holding the cable housi ng stable with a 1/2 in. wrench.

TIRE & WHEEL MAINTENANCE
NOTE: Due to a wide range of driving conditions and techni ques, tire maintenance will vary.
Ariel Atoms are equipped with ultra high performan ce, wet/dry (not all-season) tires. Tire sizes are:
Front 195/50R/15 or 205/50R15 Rear 225/45R16 or 225/45R16
Front tire pressures of 18 PSI, and rear tire pressu res of 20 PSI are the recommended tire pressures for
most applications. Minimum and maximum tire pressures ar e listed on the sidewall of the tires.
Drivers should inspect tires for proper pressure and tre ad wear before every track event. A wide range of
wear patterns are possible due to different driving co nditions.

If you are losing traction it may be time to change t he tires.
Suspension settings may affect tire wear patterns.
Grainy tread may indicate a suspension issue.
Tires may last up to 20,000 miles (32,000 km) under conservative driving conditions or as little as 300
miles (480 km) for track conditions.

The wheels should be re-torqued before every track eve nt. The lug nut torque is 80 ft-lbs.
Most Atoms have different size tires on the front an d the back, and cannot be rotated. If you car’s tires a re
the same size, rotate them every 500-1,000 miles (800- 1600 km). Dismount the tires from the wheels
before rotating them.

A-ARM ADJUSTMENT
A-Arm adjustments are made with the double threaded "adjustment thimbles" (see photograph) which are
located on both the front and rear upper A-arms for u se in adjusting wheel camber. The same mechanism can
be found at the rear lower A-arm for toe adjustment . The adjustment thimbles are secured with lock nuts whi ch
must be re-tightened after any adjustments are made. The vehicle must be re-aligned after any camber
adjustment is made.
