Awesomatix A12 - Non-Standard Parts 

It’s an old MRT PTX, I’ve had it over 10 years.

You don’t need to use a setup station to set the caster and camber. Choose the caster post for the amount of caster you want to run. Then the camber is indexed on the lower arm so you pick a camber angle, set it on the post and that’s it. Toe adjustment is done as normal with track rods, and you can use setup gauges for this if you wish.

Unlikely for the time being I’m afraid. I don’t have a gear diff for the car and we don’t use them in the UK.
