It was mounted on the outside, 2.5mm slided in, otherwise the rods would come in contact with the bones.

I will try the inner hole next week. (didn't have time to screw in the 1.5mm set screws into the inner hole.)

The 3mm bar was a little overkill for our track, though.

There was one thing that I was trying to figure out, the car was good in the infield and fast on the straight (hey it is a serpent anyway - could keep up no problem with mods engine cars), but I had to get off the throttle sooner on the straight to make the line tighter on the sweeper. Too much power going in the car would just oversteer in the middle of the sweeper off power.

It felt like part the rear outside tire chunked. But the tires were all in a good shape in the entire 30 minutes race.

That's something I will look into it next week.
