1991 ACURA NSX wheel alignment

Front Wheel Alignment Adjusting Procedure

Adjustment

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

suspensions and capable of immediate feedback.

The NSX 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 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.
