what pinion should I use?

[bassguitar]

Hey Y'all. I've had this car for a while, but my interest has recently been renewed, and I've got a question re: pinion gears.

It's a TA03F. I just got a venom 17T (after my 16T speed gems broke) and I'm not sure what pinion to use. I have a 24T or a 32T that fit my white black 48p gears, and a 14T that fits my white metric 64p gears. Right now I've got the 24T on it, but am wondering if that's the best choice?

BTW - I do have a full bearing set, ball diff, rooster esc (down to 15T) in it.

Thanks!

well, as a good rule to go by, look at what stock gearing is , which is based from the manufactor off of stock tire hieght, and a stock 27t motor. Rule of thumb, drop 3-5 teeth when going to a modified motor.
