The GKTECH V2 350z/ G35 Front Upper Camber Arms (FUCA's) are used to adjust front camber and caster. When you lower your car negative camber is introduced. This then reduces the contact patch of your tires and thus available traction. Our front upper camber arms will get this issue sorted! When designing these arms we were able to incorporate more clearance in the balljoint area from the inner wheel well by 0.39' (10mm) to assist when the upper arms are extended. These arms are a direct replacement of the standard arms and allow for -0.98' (-25mm) through to 0.59' ( 15mm) of adjustment compared to the OEM arm. With the OEM FLCA we have seen these arms adjust camber as low as -5.5 degrees all the way through as high as 1.0 degree! With our adjustable lower control arms we have seen as low as -11 degrees of camber showing a great range of usable adjustment. As a completely unique design we have now made it possible to adjust caster, by using stackable shims it allows you to further increase adjustment by or – 1 degree of caster. These arms have been CAD designed, FEA tested, they are laser cut from high strength steel, are TIG welded and to finish the arms off they're E-coated (electrophoresis coating) for rust prevention. The arms feature high misalignment PTFE lined rose/ heim joints, that we use in all our suspension arms, that are a common size bearing that can be found at your local bearing supplier, or if you need we do have them on the shelf and the provided dust boots will ensure that the heims last the test of time. - New feature for V2 design - Now adjustable on car (will save you a load in fitting/adjusting costs!) - Lightweight design - High misalignment PTFE lined common size bearings - CNC Laser cut from high strength steel with CNC machined ends. - CAD designed, FEA tested and TIG welded - Balljoint/ Inner wheel well clearance Vehicle Compatibility: - Nissan 350z - Infiniti G35
