I prefer the one where you use yokomo parts since it's easy for me to order here in Asia. 
Is it in tamiyausa.com? I'll try it out.

Unless the track is large with sweeping corners a one way is out.
Previous experience with spools put me off, tendency if the car hit anything you always ended up with somewhee in the drive train broken

Every track will be different...but in most cases you will see guys running a oneway or spool at the big races outdoors.
Unfortunately yea you will break more things using either of those :P I've used the diff/oneway/spool and each has it's advantages.
CSD...I have the parts list needed and pics from my assembly I can post later tonight.

Nexus, thanks in advance. I decided to get those spools, but when I tried ordering in a hongkong hobby shop, they were out of stock. 
And I needed them because we'll be having a national race here at our local track. So those yokomo diff conversion is my only way now.

Hey I found this on another forum,
Tamiya Parts:
51055 TRF415 Ball Differential Pulley (35T)
53379 3mm Lightweight Diff Ball Set [Or 53124 Tungsten Carbide]
53030 850 Sealed Ball Bearing
51092 TB Evo 4 46mm Swing Shaft
Yokomo Parts:
ZS-501 MR-4 Differential Outdrives
ZS-506 MR-4 Diff Rings
ZS-507 MR-4 Thrust Race
ZS-508 MR-4 Differential Bolt and Locking Nut
Is this correct? And do I still need the 51092 TB Evo 4 46mm Swing Shaft? My 415 is the original version.

TRF 415 Ball Diff
Tamiya America is fully aware that many of our U.S. customers are racing on carpet. As we have found it is preffered to have a ball diff in the front for best performance. At this time Tamiya does not offer a front diff as both the Asian and European markets have no need. This is due to the fact that racers in those markets run mostly on sweeping high speed flowing tracks, hence the dominant choice of one-way cars.
Interim solution
In the interim, Tamiya America recommends the following Yokomo parts to directly fit a ball diff on your 415.
YOK-ZS-501 complete diff half's
YOK-ZC-507 diff thrust bearing set
YOK-ZS-508 diff adjusting kit
The stock Tamiya 415 diff rings will work with these parts as well as the stock rear pulley. Note: depending on what suspension arm system you use it may be necessary to use either 42mm or 46mm universal swing shafts. This is a interim solution and we hope you find it useful. For you TCS racers out there, please note that this modification is not TCS legal

As a guideline, if you need to run a one0way, run it with dual one-ways.
For a spool or Diff, run a locked centre.
And regardng the tweak issue... this might sound stange, but since I've a) put the centre post on the conversion, and b) started using the Tamiya/RC champ Ti and Al screw kit (Ti underneath, Al on top), I've not had a major tweak issue, the car stays consitent between runs.
If you use the Ti/Al screw kit, just make sure you have a good Hex driver, with a square edged tip... otherwise you can just end up striping heads of the screws.

Not sure which Tamiya drivers are at the Nats in Stockton but this is a pretty sweet custom topdeck for foam tire racing!

Maybe it's J.Numans...not sure.

If you look closely, (rc50 site) it lloks like a 4mm chassis as well. I like the use the chassis posts...look alot cleaner than my rigged system

Looks like TRF Driver EJ Evans car.
He normally has a red pit towel.

Interesting to see how all the TRF drivers who are fast rubber tire racers do on carpet using foams.
