I'd advise against this...
You will not replicate the road course environment needed to set your car up properly at an autoX.
I built suspension components for a number of years (Was a manufacturer of custom on car adjustable stuff for old Datsun Zcars) and also won a regional autoX title back in the 90s (mix of prepared and modified group). The worst thing you could do is setup a roadcourse car on an autocross course. The dynamics required to fully exercise your car's suspension won't exist in a parking lot.

Dez, The first thing I'd do is the control arms, bushings and toe kit. Then I'd setup the car, scaled and aligned with numbers of another car you want to mimic, maybe Drew's.
The reality is that unless you have support at the track to help you, or have years and years of tuning suspensions on a road course yourself, and understand all the things associated with mass in motion, and the physics involved with setting up, or fine tuning a suspension to get a desired effect, you won't get your money out of Motons or other double adjustable shocks. A lot of guys don't understand bumpsteer or akerman, slip angles or the fact that a camber arc changes constantly thruout a single lap on course, both under acceleration, coasting, or under braking.
A few guys on here have it down pat. Matt C. is one of them... But unless you have a full grasp, or a support team who does, stick to the basics first until you learn how to properly compromise one to achieve good results in the other...

The one thing I am not going to do is throw a bunch of money at the car and have 10 x more car than driver. Uh-uh, nope. My car will be developed slowly as I learn what the different parts mean and what they are supposed to do. And how I can utilize them. That way when I start racing I'll know what does what, why and how. Which is essential to me.
The car is so fast now, I really dont want to turn it into an uber race car. I wanna be an uber driver. The most I'll do to this car will be over time and will include:
GT3 Lower Control Arms
Solid Subframe Bushings
Toe Steer Kit
JRZ
A-Arms
Well, I may do all that at once, but as of now I'm drawing the line there. I want the car to remain streetable even though I wont drive it on the street much.
I actually may stick with the JIC for a little while as they represent what I want my car to be, a street car that's something fierce on the track. And until I have full knowedge of bump and rebound settings how to use them and what they affect, the adjustability of the Motons and JRZ are useless to me.
Having to have someone to tell me what the car should do and when doesnt work for me, I need to know for myself.

No no Mike you misunderstood, I will just be playing around with things for fun, swaybar adjusting, canister pressure and minute things, this is not with intent to setup my car. Next week it goes in for my suspension work and is being fully reworked so that's why I dont mind messing around

That's exactly why I'm not just throwing a bunch of stuff on my car, I'm going to take my time and learn as I go. As I dont plan to be ushered at the track and dependant on someone else all the time because I do a lot of time trial events spur of the moment based on the weather. When I start racing, which wont be too far in the future, I'll just ask a ton of question from whoever is setting up my car. I'll likely be going with autometrics.
