The 360 race in NYC was great. The car was even better. The track was very smooth, high grip, with a great layout.

someone asked, so i will post for all

The tune-ability of the car was great, just kept looking for a little more each round, and the car responded. Got lucky enough to set, and reset tq each round.
ended up with
D pink front- 20 springs- 10k lube-castor shimms back- 3/4 Paragon
servo flat
ceneter shock 40 wt-copper spring-tall ballstud
batts back
Standard flex plates- 10k in the tubes
Grey rears

45.8 mm rollout Co27

Speed 12 body

In the main, was a little ruff at the start, but when i pushed the car really hard ,the new chassis brace helped the car to be very precise, and predictable ,to run it back to the front.

I ran the same thing this weekend on a low/med bite track, only exceptions being yellow rears and lilac fronts.

I do have a question about traction rolling. I was TQ and the car was amazing fast, untill the main. I put on a new set of tires, lilac fronts and yellow rears, trued to 45mm.
After I put the new tires on and went out my car traction rolled the entire main. It almost spun as well as a Top, someone suggested that maby I had to much compound on the front tires and it was rolling on the fronts, using 2/3 paragon. Any other ideas?

the fronts may have been too big. I normally run 1.750 rear and 1.650 fronts. When the bite gets high i go even smaller than that with a 1.700 rear and 1.600 front. You can try glueing the sidewall also if you need to but i dont think you will

There are 2 set screws included with the kit that go in the holes in the flex plate over the pivot ball. You want to tighten them until there is a very small amount of verticle play. This is an adjustment that ensures a slop free pivot.

make sure you have the 2 small delrin ball washers on top of the pivot balls so the set screw only touches the washer to eliminate the play

That is correct. They are 2 shiny screws that are 10-32 set screws. They can go in with the car assembled. Just make sure they go in straight.

Screw the grub screw in as flat as possible so it puts equal pressure on the black ball cap piece that sits on top of the pivot ball.

Im not sure on the orion but on the novak i gear it at 56mm roll out. From what i have heard the orion is geared 1 or 2 teeth less. I will see if i can get some info on that for you to be certain.

With a novak i gear it at 88/35 with a 1.75 rear tire. 33 with the orion would be right if i am correct on running 2 teeth less.
