XRAY - Model racing cars

I'm lokking into a brushless race system form my M18T PRO but I'm not sure which one would work best with a 2-cell LiPo setup.
The motor options are as follows:
6000KV
7300KV
9000KV

It should be a race setup. I was thinking about 7300KV but I'm not sure if this KV rating would be too high.
Also, if I would get any pinion suggestions that yould be great.

Thanks,
Markus

Really depends on the track, but 6kv is about right for racing. Too high a KV will cause cogging, make the throttle less linear, and more money spent in damaged parts from hitting walls.

Great, thanks for your help. I'll get the 6000 KV one.

From my experience, on 2 lipos they will all be very fast. I can hardly tell the difference between a 5600 kV and an 8000kV.
