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 either one of the elements (i.e. camber, caster, or the toe) is adjusted.
