90mm rollout? Wow that heaps! according to the gear chart i'd need a pinion of more than 40 tooth with a spur of 72 and tire diameter of 50mm...
You say its a big track for a 13.5 no boost, should i run boost to get the most out of the car?
This is the track is pretty good with a TC
Now that I think about it, with that Cirtix you may need to be over 100mm roll.
I think that's about the same size track from the ROAR nat's in Jersey this year, and they ran 13.5 blinky.
So yes, 72 spur would be good.
We were running 72t spur x 58-60t pinion at the iic race last week with 17.5 blinky
Most of the 12th scale setup is tires, and paying attention to the little things on the car, like toe, camber, and tires coming unglued around the edges.
