I am starting my outdoor racng and want to know how to setup my ARS on the car

And is there a basic setup for this

Most people don't seem to be using the ARS, I built the kit with ARS to start for both indoors and outdoors, best I found was raising the the inside mounts by 4mm and running the outer link above the arm rather than below, this gave a bigger change of toe. Outdoors I was running 1 to 1.5 static toe in.

Running the kit ARS set up I found the rear very inconsistent and extremely loose.

I have now gone back to the conventional rear and must admit I prefer it

I gave it a quick try at the end of play Sunday (outdoors at Bedworth). My starting setup had pretty much zero toe change, so in theory it should handle similar to the standard rear-end. It did feel pretty close. The rear was a touch loose on occasion into the corners, but I'd only set it to 3deg toe, and the standard rear actually has 3.2, so I need to change that. I'd also used a 2mm shim on the outer camber link, which is higher than the standard hubs (I only measured this after the test, as it was a bit of a rush!).

So, what I'm going to try next time as a starting setup is:
1mm on the outer camber link (this gives the same height as 4mm on the standard hubs). 1mm on inner link as normal.
0mm shims outboard
1mm shim on the post
3.2deg rear toe (this matches the solid rear end on 0 inserts)

I think its an interesting option, and it certainly didn't feel a mile away from being usable, even though my settings were off. I've ordered some more driveshafts and hingepins so I can keep two complete rear-ends built up and change them much quicker, so I'll be testing it more in the future.
