Direct replacements for the front A arms and allow you to adjust camber on the front of your 350Z or G35. These employ a special compound rubber busing to ensure smooth operation and minimize noise. The actual amount of camber you can dial in or out will of course vary from car to car based upon suspension setup, rideheight, as well as your tire and wheel combo. However, these should provide more than enough adjustment to bring most any car back into the specs one could want (please note if your car is extremely lowered in front, depending on your particular setup you might not be able to adjust back to factory specs, though you will be able to scale back the total amount of negative camber. We installed these on our own 350Z, which is lowered with Cusco coilovers, and were able to bring the car back to -1.25 degrees in the front.
