I found some specs from hobbywing motor:

They claim KV value of 2170 for the 17.5 motor. The timing is not clearly expressed but there is a note with the "specifications" that says:
"The maximum output power is the test value obtained when the voltage is 7.4V, and the ESC timing is set to 0 degrees"
From what I learned on this thread, now I assume the hobby wing motor would have some end-bell timing built in.
The motors you are apparently looking at are sensor less types and I don't know anyone running any onroad car who uses these types of motors.
