Fits:
Porsche 911/912/930 ALL 1965-89

Gain back ride quality and rear end stability with High Density Rear Spring Plate Bushings for your 911. Under prolonged use, especially when driven hard, the OEM bushings can break down allowing more slop in the rear suspension. If neglected long enough or driven under heavy load enough, these bushings will eventually deform allowing the spring plate to contact the cover plate. Replacing your factory bushings with our 25% stiffer units will allow full and smooth articulation of the spring plate, thus improving the ride quality and performance of the legendary rear end in your classic 911. Featuring a higher, "sport" durometer these rubber mounts are a great compromise between soft factory mounts and solid/spherical bearings often used to replace them.

Rear CamberMax Kit. Rear camber adjuster.
Sold per kit, 1 kit req'd per car.



Fits:
Porsche 911/912/930 1965-89
AL trailing arms only

Rear CamberMax kit simplifies 911 rear camber adjustment, making it easy to achieve aggressive negative camber settings of 3+ degrees. Instead of using the troublesome factory eccentric bolt, Rear CamberMax allows adjustment with a simple and precise screw.

Unlike the stock eccentric adjuster, Rear CamberMax allows adjustment with vehicle weight resting on the tires making it easy to read a camber gauge while turning the adjuster.

By making equal adjuster turns on both driver and passenger sides, quick changes can be made trackside even if a camber gauge is not available – try that with the factory eccentric adjuster!

Note – Fits factory spring plates and AL trailing arms only. Does not fit Sway-a-way plates or steel trailing arms.

Spring plate PolyBronze bearings
For Porsche 911, 912, 930 1968-1989 Spring Plate SAW



PolyBronze bearings are superior to plastic bushing alternatives, here's why:

Suspension mounts are coarse sheet metal pressings. They tend to be out-of-round and have irregularities that deform ordinary polyurethane bushings, pinching and binding the friction surface. Polyurethane is "grippy" with an inherently high coefficient of friction and combined with pinching polyurethane bushings create a lot of friction. The result is a harsh ride and reduced tire adhesion.

PolyBronze have a rigid bronze bearing core that does not deform. The polyurethane jacket absorbs mount irregularities while the bronze inner bearing remains true, providing a free-moving machined-fit that rides on a precision race. Provided grease fittings make re-lubrication a breeze and a figure 8 groove keeps grease in place.

The combination delivers zero squeaks and friction-free suspension movement. Well suited to street or track, ride quality.

PolyBronze is a precision bronze bearing encased in a polyurethane jacket. The combination delivers a smooth-ride with the extreme performance of a metal bearing.

✔ No squeaks or binding
✔ Extremely smooth ride quality
✔ Easier to install than rubber bushings
✔ Integrated grease fittings and grooves

Note – 1967 spring plate bushings changed mid-year. The following '67 chassis numbers transitioned to the late style '69-'89 style bushes.

• '67 911 from Chassis Serial Number 307 325
• '67 912 from Chassis Serial Number 354 938
• '67 911 S from Chassis Serial Number 305 101 A

All earlier '67 chassis numbers use the early '65-'66 style bushes.
