Not being funny, but this site will not only answer your question, but it will become your good gearing friend:

http://www.gearchart.com

* Click on Gearchart Creator
* Select your type of chassis/car
* Fill out the spur & pinion sizes
* Click on the Gear Ratio button

If you want to get the rollout then additionally fill out the tire diameter size and then click on the Rollout button.

No, you use the same formula to calculate (Spur / Pinion X 1.7). You will find the 64P gives you a wider range of gearing options than 48P.

Please take no offence and I am not sponcered by these people but this little tool makes breaking in diffs take alot less time.
Here is a pic.

http://www.niftech.com/catalog/index.cgi?mode=new
Scroll down its about 3/4 the way down.
Part #2400...


Then all you have to do is tighten it to your liking on the track.
I usally just tighten it down to wear I can hold one tire and the spur and the it takes almost all my twisting ability on the other tire to make the diff slip. That has been my SOP for stock and 19T.
Hope that helps peeps,

Hi all

I just ordered a T2 007, wich will be my first xray, so i have no ideia what is more prone to break. My LHS doesnt stock parts for xray, so i was wondering wich parts should get as back up. My present list:

C hubs
Suspension arms
plastic shocks set
Uprights
drive shaft cap
steering bushing
...and maybe a bearing set

do you have any other sugestions?

I will be running EU version, exclusively ruber on asphalt. 90% of time on long, medium to low grip tracks.

Thanks in advance

Steering knuckles, tie rod ends, M10 screws since you'll lose it most likely when the knuckle breaks. I just switched to aluminum rear uprights and plan to do the front knuckles soon.

Itchy,

The first thing to do is change the bumper to a PDub/Parma. Make sure you clean and re-oil all the bearings when building you car. Take your time and do it right.
