Now the car runs an 83 tooth spur gear, and i've been recommended to run a 24 tooth pinion gear. Would this be the best set up to go with?
Thanks,

You need to know what motor is going in there and the internal drive ratio to work out what pinion range you'll need. Faster motors will require smaller pinions.
If your running an 8.5t motor at a guess id say get pinions ranging from 21 upto around 25 and do a bit of trial and error. You'll end up changing them anyway for different tracks (ie, outdoors you'll likely want more top end)
mY spur on my b44.1 is 84T and I use between an 18t and 22t pinion on it depending on the track (6.5T motor though). I would imagine the internal drive ratios are somewhere close.
