Just use 93t normally but have 90t as well if i need to really drop the ratio down.

Nah I'm not even in the US. If it is 21.5 blinky then 30-35 should be about right. If silver can then 25-30.

our track is quite big and flowing though as for diff balls.... also my diff seams to loosen itself after a slight accident.....will sand my diffs for the next meet....also might try 3mm balls

am running 21.5 blinky and i have 72 spur 24 pinion (48p) which is a fdr or 3.0 and the thing flies.....

The diff will slowly loosen itself over time. Think I need to re-adjust mine every 3-4 meets.
What motor and esc are you using? I'm down to a 2.4 ratio so far on my blinky car. I think I may push it further as it still spins the wheels quite easily.

Think you may have it the wrong way around. The lower the ratio the less likely you will spin the tyres.

the bigger the spur/pinion the less rip you get out of the corners and would be easier to drive (smoother)....
thats why you are getting wheelspin because you have gone too low and out of curiosity how many years have you been racing and what classes???
in most cases with gear ratios and motor winds.....the lower the number the faster it is usually

think you have.....if thats the case then a 13.5 motor would be slower than a 17.5 motor....

When keeping the motor and everything else identical, as you lower the gear ratio the car will have a higher top speed and lower acceleration. Lowering your gear ratio does not increase acceleration and top speed.
What does the number of years I have been racing have to do with anything?

You are confusing yourself going into motor winds. That is different to gear ratios.
When keeping the motor and everything else identical, as you lower the gear ratio the car will have a higher top speed and lower acceleration. Lowering your gear ratio does not increase acceleration and top speed.

with extra speed comes extra acceleration.......
try it for yourself and see how it goes.....
as for years racing.....let me reword that, what other cars or classes have you run??
also what ratio are you thinking of running???

3Racing spur gear uses 1/8th diff balls stock.
On the gear ratio Jpap is right...the higher the ratio is numerically the more wheel spin you will get. The closer to 1:1 you get the less wheel spin you get.
This is true...however more top end does not mean more wheel spin...more acceleration = more wheel spin. Top speed and acceleration have an inverse relationship. Meaning the more top speed you have the less acceleration you will get...the more acceleration you have the less top speed you will have.
