For those of you with an old DAX (before MK4) we can tell you that DAX has change the rear spreader plate to make this possible (The holes distance has been changed).
Let me know if you need the dimension. They also have a nice temporary setup spreader plate for the front side to make the installation easy.
So we have here setup the rear toe, this is just the start.
If you rear suspension is already installed, and the body is on, this would be a “Pig Job” because you need to dismantle the totally rear suspension to adjust the toe-in.

THAT IS NOT TOTALLY TRUE.

A UK Cobra Forum colleague did just design a set of tools to do this job with out the need dismantling all the components.

It looks pretty good and smart.

FROM TODAY WE CAN SAY THAT ADJUST THE TOE-IN AT THE REAR SUSPENSION WITH A JAG DIFFERENTIAL IS AN EASY JOB.

To check the rear toe you can use some home made tools with aluminum angle bars and a laser level. See next picture.

Alignment 01

We talk about Alignment and in particular the “Rear Trust Line”, Caster and Camber and how to measure.
We are speaking here from a Jaguar XJ suspension but others can check for equivalents situations.

STATEMENTS
- Alignment is not a mystery.
- It is something that we can do our self.
- It is always better to check it at the end by a professional. For confirmation purposes and final touch.
- To do any alignments measurements you need to level your car and set it at rideheight.
- Remove the springs and shocks is necessary.
- You need to simulate the length of the spring and shock combination by using a steel bar with two holes that will fit to the       bolts of the shocks.
- For a DAX the front distance between the bolts are:
- Front 275 mm holes of 12 mm
- Rear 315 mm holes of 16 mm
- Those distances need to be check at your Cobra on a garage lift before you start to fabricate, the dimensions here are as a reference and will fit only some DAX Cobras. (Depends of your spring loads and tire dimensions and inflation)

HOW TO START OR WHERE TO START?
- Rear Toe.
- Rear Trust Line
- Rear Camber.
- Front Caster.
- Front Camber.
- Front Toe.
- Front Toe Change or “Bump Steer”

REAR TOE
When we have a Jaguar differential the Toe should be set by the bottom fulcrum shaft via shims.
You need to put at both sides the same amount of shims (this is a must!) to achieve the angle that your kit vendor has define as optimal. (By DAX this is between 10 to 30 minutes in total (remember not each side but the total of both) See bellow
