C5 Camber Plate Kit - DIY!

It actually took me a little while to get around to adjusting the alignment on my Corvette to something much more track focused. It makes a huge difference!

Features

Keeps your camber settings locked in place
More "known" adjustability using facets of polygon vs. OEM eccentric
Far more resistant to curbs/berms/rough track surface conditions
2 files are available: hexagon and decagon. Any polygon should work really, but eventually you're going to compromise the holding power of the face if it gets shorter and shorter.

Where to get

This kit is open source and licensed under CC-BY-NC-SA. You can download the .DXF to cut it out yourself, upload it to SendCutSend or other machining service provider, or purchase a ready-to-go kit from me directly. Link to the plates: millsymotorsports.com/free-parts Aside from the plates themselves, you will also need:

6x 120mm long M14 x 2mm bolts, preferably Grade 10 or higher
6x High strength M14 x 2mm nuts
12x M14 Washers
Red Loctite
These are not necessarily required, however, they may be needed to adjust caster and camber (if it's too much) - front upper control arm shims. A DXF is forthcoming!

I used 1/4" thick 6061-T6 aluminum to make the plates themselves.

Personally, I chose to use Grade 12.9 black oxide socket head cap screws. These will have mediocre corrosion resistance, but they are crazy strong. I used high strength, yellow-zinc-plated nuts. For the washers, I used 316 stainless washers. All of these items can be found on McMaster.

Installation

This installation is actually very straight forward.

SAFELY lift your vehicle. Verify it is solidly resting on jackstands rated to hold the weight of your C5.
Locate the front lower control arm, starting on either side. Take note of the current position of the eccentric.
Using a breaker bar with the appropriate size socket and a wrench, undo the bolt and nut. It's also worthwhile to loosen (but not undo) the other eccentric of the same control arm for ease of install.
Remove the bolt. This may take some wiggling, prying, and gentle tapping.
Clean the machined surfaces on the cradle with a rag and some solvent.
Either match the prior setting of the eccentric, or go nuts and max it out. With the current design, I'm around -3.2 of camber up front, and around -1.5 in the rear.
With both plates placed, ensure they are of matching settings on both sides.
Slide your bolt and washer in. On the other side, place a washer over the threaded portion of the bolt and apply a small drop of red loctite.
Spin the nut on. Grab your favorite 1/2" drive torque wrench and torque to factory spec. Let the loctite cure!
Repeat for the front and rear. I believe the torque spec for the front is ~120 ft lbs, for the rear, ~75 ft lbs. Verify what a manual says first!
Get your car aligned ASAP!!!

P.S. These parts should work on all C6 steel frame cars as well.
