Fitment Information Nissan 350Z (2003, 2004, 2005, 2006) Specs & Features Sold as pair. You must re-use your factory ball joint seat when installing these arms What’s in the Box: 2x Front Camber arm Typical Range +0.5 to -5.5 degrees *This will NOT Fit 2007 Infiniti G35 Sedan** Legal only for use in competition vehicles which may never be registered, licensed, and/or used on public streets or highways; and also for use in other exempted vehicles. On vehicles which are lowered excessively please check for clearance between the arm and the chassis metal through the full range of suspension movement. Contact with the chassis can damage the arm and/or adjusters ** Product Description Our front upper camber arm set is designed to provide the maximum range of adjustment on your Nissan 350z and Infiniti G35. Unlike other arms on the market that require you to remove the ball joint for adjustment these arms are easily adjusted using a 19mm wrench without removing any components.  These arms include a high quality serviceable ball joint.The factory 350z and G35 chassis are designed in such a way that the upper arm can only be extended to a certain length at a given ride height before coming into contact with the chassis. Our arms generally allow a wider range of adjustment at any given ride height than is able to be accommodated by the factory chassis control arm recess. Because of this, if you are attempting to reduce the negative camber gain associated with lowering your vehicle, depending upon the alignment specifications you desire, you may need to modify the factory control arm recess in the chassis to provide more clearance for the control arm to extend into. If you do not wish to modify the chassis control arm recess, that recess will restrict the overall length you can adjust the arm to, limiting the amount of camber correction you can achieve.
