JPSS are a Knock Out by design and construction. The bearing plates are made of stainless steel. The hardware is stainless steel. Our bearngs are the finest made in America available. Of course none of this matters if they are not the most functional in the industry. It starts with a hard mount system. Some 5th Gen Camaro owners will cringe at the thought of drilling six mounting holes in their strut towers, but most will agree it makes sense when they understand why. We don't want it to move. Period. Anything that clamps in place can move on impact with a pothole or gator-back. Bolted in place, the only way to move a JPSS camber plate is to move the entire strut tower.
JPSS Knock Out Camber Plates deliver 2 full degrees of adjustment. Not 1 degree. Not 1 degree split between caster and camber. 2 full degrees. If you want to add caster, and we highly recommend you do, use our Caster Locks or of Caster Bolts. Camber plates on a 5th Gen Camaro are reserved for Camber and Steering Angle Inclination (SAI).
Steering axis inclination acts, with caster, to provide a self-centering of the front wheels. When the wheels are in the straight-ahead position, the ends of the stub axles are almost horizontal. When the wheels turn to either side, the effect of steering axis inclination is to make the ends of the stub axle tend to move downward, but this is prevented by the wheel. The stub axle carrier then must move up, which raises the front of the vehicle. When the steering wheel is released, the mass of the vehicle forces the stub carrier back down, which pushes the wheels back to a central position.
The SAI angle is created and measured in degrees. It runs from the lower ball joint through the upper ball joint, or on most front wheel vehicles, through the center of the strut mount. The illustration uses ball joints to represent the angle. This measurement of degrees includes the measurement from lower ball joint to the upper ball joint or the upper strut mount and true vertical (the tire actually sitting straight up and down). The SAI angle doesn't include the camber angle. This is because Steering Axis Inclination is a non-adjustable angle.
We recommend using the JPSS Knockout Camber Plates to increase SAI and adjust the majority of camber at the knuckle. Combine this with JPSS Caster Locks to achieve optimal front end geometry and handling.
