Camber Plate Install

Cut the template from the instructions


Remove the top hat nuts and put the template in place

Use a pointed center punch or similar to mark the center of the bolt holes

A center punch will help you locate and center the drill bit

Start with a small bit like this 5/64″ and LIFT THE CAR / drop the strut or you will drill the top hat

Then a large bit for the bolt size like this 7/32″ bit

Open the final 6 template holes to allow the hardware through

Cut the inside box of the template

You can discard the cut out portion

You can position the cut template using the camber plate bolts through the holes you just drilled

Trace the inside of the template

You now have a cutting guide

We cut on the lines with grinder cutting wheel (don’t cut past the corners) and finish cutting at the corners with a sawzall or jigsaw or hacksaw blade for clean corners

Test clearance and trim and clean up your cuts as needed, ream out any offset holes

Bolt it all together and once again test travel and clearances

You can trim back any portions of strut tower still showing like on the right here

In the rear you can trim the vinyl only as needed for a clean appearance
Coilover Install - Front

Front adapters must be modified to clear the hump behind the strut tube

You will weld above this, so the cut does not need to be pretty

Rounding the bottom to match the curve

The hub should be secured on a flat and level surface

The hump we made room for

We found the strut tube to be perpendicular to the bottom of the hub (where it sits on the ball joint)

First measure the work surface

The top of the adapter should be in the same plane (exactly the same measurement) as the work surface

Measure the other direction

Compare to the work surface (if our surface was flat and level, the top of the adapter should be tacked so it’s flat and level also)

A magnetic protractor works great too
Coilover Install - Rear

Measure the relation between hub and strut, difference should be 15 degrees

Use a lug nut or 2 to hold the drum on tight, then measure, difference should be 15 degrees

Again, a magnetic protractor works well (if you have good eyesight)

Example of the 15 degree offset: 95 degree hub

Example of the 15 degree offset: 80 degree strut

NOTE: Make sure you position the adapters correctly. 240Z and Early 260Z owners should receive four 6″ adapters. Late 260Z & 280Z owners should receive two 6″ adapters for the front and two 9″ adapters for the rear. You’ll be able to weld directly to the hub, BUT DOUBLE CHECK YOUR LENGTH AND DESIRED ADJUSTMENT RANGE! The strut should be threaded into the adapter at least 1.5″-2.0″ for strength and stability. MAKE SURE YOUR ADAPTERS ARE THE CORRECT HEIGHT for the stance you want to achieve.
