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

I use this set-up and it works wonderful, the front diff has held up much better than my rear diff. If you want to lock the center pullies, you can buy a locked pully that replaces the one way. I have thisnad it works fine, but the better option to save wieght is 1 wider pully. I don't know if you can get this without buying the parts set, but here are the links to what i believe are the right parts.

Now, i have a question of my own. The belt stabilizer, i know this helps keep the belt on track, but does it cause extra friction? is it worth using?

Tony, you dont need no diff. One-way will work fine on Carpet. I will be running a Tamiya with a one-way. You will be ok.

hey guys, from what i'm reading some of you are running on carpet and i was wonder what you were doing for tires. I was using 28mm rear and 26 front because that's what i had from my old car. the 26's in the were working fine, the ball cups rubbed, not a big deal it happens on alot of cars. the 28's in the rear rubbed on the shocks. they rubbed sooo bad that they almost cut right to the ball stud that holds them on 
i was wondering if any of you carpet goers have this problem and how you solved it?

What hexs do you have on the car, by this I mean thickness? Tamiya makes several diffrent ones. They have 4mm, 5mm and a 6mm. You can also just space the tires out with some washers, till they don't rub.
By the way 28mm foams should fit all the way around with no problems.

k thanks, that what i thought, i have the 4mm blue ones(i'm pretty sure without checking) so i'll buy the 6mm ones cause my car isn't 190mm wide either 
until then, i have they strangly larger red washers that came with the car, are those by any chance wheel spacers?

Another question 
. If i remove the wheel spacers (standard blue ones) from the rear hexes would that make it turn quicker (more steering) because of the reduced track width or should i add spacers to give more steering?

Pretty sure thats right. Check out the TA05 manual for how its arranged. Very basic 
You can use the HB Cyclone shaft too. They have one for locked gears and it fits the MSX if the TAMIYA 51214 Centershaft is not availible.

Has anyone try using the spool on the rear, locked mid gear, and a front one-way with foams before? Might almost be like the gas sedans. The rears on those are almost locked(like the 1/8-scales).
I am going to pin my extra rear diff and try it out. Something to do
