My Nismo 350Z in its stock form has a positive camber. I know this because my tires are wearing from outside on all four corners. Now I want to know if stock 350Z needs new front A-arm and rear camber kit to change the camber setting or can STOCK camber setting be changed without the camber kit.

 

you can still change the camber but only to some extent. you can correct the problem with your stock A-arms.

and also, RTFM heheh!

 

These cars are set up with neg. camber. after looking in my manual front suspension you will need to put a system that is adjustable.Caster camber kingpin inclination is not adjustable. (Decimal degree). Camber minimum -1.33 nominal -0.58 maximum + 0.17. Caster minimum 7.42 nominal 8.17 maximum 8.92. Kingpin inclination minimum 4.33 nominal 5.08 maximum 5.83. Total too-in minimum 0 nominal .04 maximum .08.

Rear suspension is adjustable from bolt in front of lower link. Toe from bolt in rear lower link. Camber rear in decimals minimum -2.08 nominal -1.58 maximum -1.08. Total toe-in minimum .043 nominal .075 maximum .106
