Anyone remember which way to stack the spacers for anti squat max?

 

In general, big spacer goes on top and little spacer goes on bottom. Depending how far you're lowered, mounting it the other way will cause the control arm to hit the body. Then put the spacer on the bottom for stock-ish position or top for their "pro-dive" or anti-anti dive or whatever you want to call it.

 

In stock form, the back of the control arm sits higher then the front.
Larger spacer on top = arm sits more horizontal with the ground.

LESS anti-dive is what you get. It still has SOME anti-dive in this configuration though.

 

And to add to this, with my control arms I can easily swap between anti-dive settings. I tested it both way and found little difference (butt dyno) just driving around but I did find that too much anti-dive had a big effect on the ability to get the car rotating on lift. So mid corner, car is relatively loaded but you came in a bit hot. You want a tap of the brake or engine lift to get some rotation but no matter what I did, the car just pushed. Other drivers noted the same exact issue when I had other seasoned vets try it. It definitely caused a dynamics issue and was massively improved just flipping the spacer.
