I set the arm at 90 degrees to the servo and the left/right steering is very close. Might be around 4 points on the epa.

I think anywhere within 10 points is not a problem.
Just experiment with the arm angle a bit.

I think that is not possible with the suggested link length of 44.5 mm. What length are you using?

If u r using Futaba 9451 try 42mm...with horn @ 90º.

I don't think that length is possible with the stock ball cups and rod...

Try it...it worked on mine. Want visual proof too?....

You'll need to cut the balls and rod a little.
We'll look into this issue and see if we can improve it for future kits. Please provide info on any mod you made.

Yes please...

Below is some of my 710 picture after about 2 hours driving (1 gallon). When you watch my pipe and bumper, you will realize that Im serious about having some T-boned and couple of airshow.

Please look closer to the DRS picture, that happen when I mount it on highest position. Even in normal/lower position that still can happen, when your rear ball got tweaked after hard impact on the rear wheel.

One more thing, the car weight is 1670 with personal transponder.
