C rating depends on whether the motor can draw the current, if it only pulls 20A max then a 25C or 100C battery isn't going to make much difference.
I would say a 13.5 would be as fast as you want to go with these, probably equivalent to around 13-15 brushed with what you can get out of them these days. Keeping the ESCs to blinky mode means you can use cheap ESCs like the Citrix Stock which have no boost options, but if anyone has a spare high end ESC with blinky mode then they won't have to buy a new ESC for similar performance.

They weren't built around todays speeds, here's the 85 Worlds open class, so modified motors and as fast as they could go. You could likely match them with a 21.5T today.



Might as well pop this in here as well, part 1 of 5.
