While I'm waiting for my kit to arrive, I mocked up a pinion and the brass sleeves. I can get a 51 in there no problem. That gets FDR to around 3.72 (51/76), no bueno for GT3, but real close for GT2. And looking at the optional motor mount, I think there's even more room:
If you can get a 52 in there, you're at 3.65 and that's close enough. Plus, you can probably fit a smaller spur in there without adjustment with the bigger pinion.

A person I race with locally in VTA came up with a solution to get the gearing/FDR he wanted for his TB04. He has access to a machine shop, so he fabricated a part(s). Tonight is his debut of the TB04 in VTA. If I can get a good picture of his solution I will post it.
At our local track we typically run anywhere between 3.6-3.8 FDR. From talking to him, he could go much lower. He would never sell/manufacture anything, but at least it might inspire others to duplicate his solution.

I've had the kit for about two hours, and I'm no longer sweating gear.
That's a 54 (as big as you can go before you hit the screws), it is a PRS pinion (wider than a CRC), it turns and doesn't hit. It looks sano, and took about two minutes using a dremel sanding drum. With a 72 tooth spur, FDR of 3.33. The instructions give a measurement for pinion location, it's 14mm, that's where mine is.
I put a pm into Fred and asked if this is okay per TCS rules. For the life of me I don't know why it wouldn't be. They allow tb-03 users to mill the chassis so a lipo fits flat, and this isn't part of the chassis.

Sometimes I think Tamiya is still in this little world of theirs where only silver can motors and shotgun style batteries exist.
