Wheel Alignment

Height

NSX/NSX-T four wheel alignment requires the use of equipment designed specifically for four wheel independent

suspensions and capable of immediate feedback.

NOTE: For proper inspection/adjustment of the wheel alignment, check and adjust the following before checking

the alignment.

• Check that the suspension is not modified.

• Check the tire size and tire pressure.

• Check the runout of the wheels and tires.

• Check the suspension ball joints. (Hold a wheel with your hands, then move the wheel up and down and right

and left to check for wobbling.)

• Check the height of each suspension (see below).

Standard value

Front:

Ground clearance to the center of the lower

control arm bolt
Rear:

Ground clearance to the center of the toe con-

trol arm bolt

Height inspection:

• Before checking for the height, bounce the car up and down several times before measuring.

• Check the height with the car empty, parked on a level surface, with properly inflated tires (tread wear indicators must

not be showing). If the height is out of specification, load or unload the car as necessary.ProCarManuals.com

Front Wheel Alignment Adjusting Procedure

Adjustment

NOTE: NSX/NSX-T four wheel alignment requires the use of equipment designed specifically for four wheel independent

suspensions and capable of immediate feedback.

The NSX/NSX-T suspension can be adjusted for camber, caster (front only), and toe. However, because each of them

relates to the other, the camber changes when the toe is adjusted for example. Therefore, the total adjustment of the

front/rear wheel alignment is required whenever one of the elements (camber, caster, or toe) is adjusted.

Front wheel alignment adjusting procedure

Check tire pressure on both sides.

Check the ride height on both sides.

Measure and adjust both camber and toe of the

left side.

Measure and adjust both camber and toe of the

right side.

Adjust caster on both sides.

Measure and readjust both camber and toe of

the left side.

Measure and readjust both camber and toe of

Front Wheel Alignment Adjustment Procedure (cont'd)

NOTE:
NSX four wheel alignment requires the use of equip-
ment designed specifically for four wheel indepen-
dent suspensions and capable of immediate

feedback.
The ride height is very important for setting the align-
ment. For every 10 mm of change in the front ride
height, the camber will change approximately 10

minutes.
The front alignment settings on the NSX are

interactive.
A slight change in toe will dramatically change the
camber.
1. Drive the car on the alignment rack.
2. Check the tire pressure and ride height as described on page 18 - 6.
3. Center the steering wheel.

Toe
1. Measure the length of the threaded section on
the right and left rack ends.
Standard: 11 mm for shoulderDifference between right and left: 1 mm max. 2. If the measurement is out of the specification,
loosen the locknut and adjust properly.
