Anatomy of a Spliff aka (Rubber Diff)
Necessity is the mother of invention they say...For the Reedy Race of Champions One-Ways are not permitted, the options left are Ball-Diff, or Spool. A Ball-Diff should have better corner speed, while the Spool should have an advantage on corner exit. The One-way was developed to offer the best of both worlds, thatís where the Spliff comes into play, part spool, part diff it does it all.
Here is a simple way to make a diff feel almost like a spool, and itís adjustable for just the right amount of drive off the corner while maintaining corner speed especially thru the high speed sweepers.
You will need 6 black o-rings.
1. Disassemble diff, reassemble using thick diff lube on diff balls.
2. Lube up 2 o-rings with a thick diff lube, like Losi purple, or Tamiya Anti-Wear grease, place 1 o-ring on each side of the diff
3. Do not use the thrust balls, place 1 thrust washer over each o-ring on each side.
4. Insert diff screw into diff, on the other side do not use diff spring, instead replace it with 4 o-rings (dry, clean).
5. Assemble with diff nut, torque as tight as you dare.
6. Adjust as necessary. Much like an off-road slipper, tighten until you can barely here it slip on hard acceleration. Check again after a few runs as the o-rings take an initial setting. After 5 runs it should hold this setting.
A properly built and adjusted Spliff should last quite some time in between rebuilds. I used the same Spliff throughout the entire Reedy Race weekend, and had some shakedown time on it the week before with little to no wear on the outdrives, and no adjustments needed.
