The GKTECH R33/R34 Skyline Front Upper Camber Arms (FUCA's) are used to adjust the front camber on your Skyline. When you lower your car negative camber is introduced. This reduces the contact patch of your tyres and thus available traction. Our front upper camber arms will correct this issue. The GKTECH camber arms are a direct replacement of the standard arms. These camber arms allow for 0 through to 30mm of adjustment compared to the OEM arm. When used with an OEM lower arm we have seen as low as -4.5 degrees of camber and as high as 1 degrees on a low car! The GKTECH Front Upper Camber arms (aka FUCA's) are built to a high standard and are far from the generic garbage that most people are used to but at a very reasonable price. These arms are CAD designed, FEA tested, track tested, have CNC machined ends, TIG welded and to finish the arms off they're E-coated (aka electrophoresis coating) for rust prevention. To top it off we're exclusively using high-quality Teflon lined bearings. - Feature 5/8" Teflon lined spherical bearings which eliminates the flex found in factory rubber bushing offering a more direct and predictable feel. - Manufactured from 4130 chromoly sheet with CNC machined ends. - CAD designed, FEA tested, CNC machined ends, CNC laser cut and TIG welded Vehicle Compatibility: - Nissan Skyline R33 GTS - Nissan Skyline R33 GTS-T - Nissan Skyline R33 GTR - Nissan Skyline R34 GT - Nissan Skyline R34 GT-T - Nissan Skyline R34 GTR
