Assuming you have an SC10 4x4 FT kit.
From there, I would suggest that you:
- Identify the conditions you plan to race it in
- Locate a setup from a local racer and / or, find one on AE site that best matches your conditions
- Make sure you have 0.5mm shims in your kit to put under the sun gears in the diff, when you do this, make sure you DO NOT put the shim between the diff cup and the diff case (an addendum should say this)
- Watch for any binding when building your transmission cases, you may need to SLIGHTLY back off the screws till it feels smooth if you do, if its real bad, contact AE for a new diff case
Now, if the conditions you are racing on are large loose tracks with big jumps and or loose tracks in general and you find you do not have the rear traction you need, probably the first hop up I would try is the M2C rear toe in block at maximum toe setting. I found when using this, it really locked in the rear end. Its even a nice hop up to have right away since you can set it to "stock" as well as a variety of other settings quickly.
From there, there is a variety of different hopups available that work well, one of my favorites being the Center Diff from RC Shox. Its not cheap, but I felt the benefits were more than worth the price.
