If you can, can you post a detailed list of the Yok parts (part #s)needed to make up the front diff and mods (if any) and the same for the center shaft. For the center I know we need to use avail 415 parts. Really will appreciate you sharing w/ fellow 415ers the mods you made since it looks like Tamiya have no plans of coming out w/ a front diff & center locked pulley set-up.

thats no problem at all... for the diff, i used thrust assy and outdrives from the old belt Yoke MR4TC, which will accept either Yoke or Evo3 diff rings. of course, the 415 rear pulley and 3mm diff balls have to be used up front, too... this fits perfectly in the bulkheads, no shimming or machining necessary.
the next problem was the driveshafts were too short to reach the diff, soooo... again MR4TC belt rear drives were handy, plus they were the blue lightweights, so it almost matched.
the hardest part was to find 6x11 bearings, coz the Yoke cvd's have a 6mm o.d. but i found some made by... Tamiya! fits something in a truck trans, i think.
i will grab some part #s and some pix when i get home later this evening...

But as I've already got a stack of EVO III parts, I'll leave the swap until I run out of bits. How many parts are common between the EVO III (Surikarn) and the 415?

A Arms, Damper, and some suspension block (but they are red in EVO). TRF415 has the ability to turns like the EVO with the ease of belt drive maintanance and durability. Just use Surikarn's setup I posted last time in this forum.. works great on tarmac.

Ran the 415 on saturday and sunday, its still lacking but i have come to the conclusion that its the tamiya A and B tyres as the car is far better on take off tyres. Rick

PS: What I do not understand is the 4mm spacer on rear side of front arm becuase 3.5mm I believe is the maximum. Drive greats on Tarmac! just be sure your belt is very loose (max of two tighter clicks from original point) in order to last 8 minutes on 23T stock racing

no clipping every other tooth needed. Aslo, he mentioned that the soon to be available worldwide, the delrin rear diff outdrive, is not perfect to his knowledge because it expand when turning. He prefer to use the original black plastic outdrive. Or maybe Tamiya has upgraded the release for better strenght?
