Missing parts
Anyone else here missing parts in their kit? My kit only came with 3 bearing s for the steering rack. Another at my track was missing a ball in the diff.

However, the OEM bearings are unlike any I've ever seen. The lack of drag is amazing. I built the car with them, and have continued to run them. I will replace them with ceramics when it's time.

I would start at 43 degrees of timing, 32x72, and work from there. When you run a fan, you worry less about temps, and more about feel. I would tell you, run 4 laps with this setup, then try a 31. run 4 laps, then try a 33. Once you find the right feel and speed, and lap time, run for 8 minutes and see how it feels around the 5 minute mark, if it's not fading, bump timing up a little.

Gearing is going to be more about the surface and layout than anything else. I can tell you now, you're going to need to figure a fan out, as the short stack motor is pretty sensitive to heat fade.

If I were wanting to fit a fan, which I will be soon...
I'd copy Matt's setup here.

Re
In my b5m I run a reedy 17.5 at 42 degrees timing 72/32. Thing is fast! 12 minutes on med size tight track with a 70 foot straight coming off at 125 after 8 minute. Ran for 13 mins yesterday came off at 135. Have a new souprd up fantom haven't installed yet because the reedy is so fast for a 90$ motor
