If it has the right dimensions to make the gears mesh, then fear not the dremel tool. It doesn't need to be sealed if it's a sealed diff.

The Sweep qts 32 Tires have deep wheel hexes, and will allow lots of track width adjusting spacers between the wheel hexes and axle hexes... Other wheels might not allow such an adjustment....
Sweep qts 32 hex depth: 4.28mm
Sweep exp 40 hex depth: 2.85mm
The exp40 Tires fit on the front only, if you want 190mm track width.... Happy Racing....

anyone know for sure out of the box which degree caster blocks the TC4 Club Racer comes with?
the instruction manual accompanying it is for the factory car so not sure if the one mentioned there is correct.

The club racer comes with four degree castor blocks....
As far as gear diff for the tc4 is concerned, I think the $30 Spec-R gear diff for the Tamiya TB03 (#: SPR009TB) is the best bet here, eventhough it should only be used in stock spec classes... It looks to be a fairly direct fit, and might be using the same pinion and ring gear as a tc4.... It might need some slight bearing fitment mods, but I think it's the best solution out there... I am still sticking to my ball diffs though, as you already know, but would definitely like to see what it would take to fit a gear diff in a tc4... Check it out !!!
Here is the final tally:
Tc4 ring gear(40teeth), and pinion(16teeth): 2.5 ratio...
Tb03 ring gear(39teeth), pinion(16teeth): 2.4375 ratio...
I guess you guys can run two tb03 gear diffs or a rear tb03 gear diff and a front tc4 spool to create a slight underdrive system... Have fun guys, and happy Racing....

That would be a 2.5% underdrive to be correct....

The tb03 geardiff will not work. I tried that two years ago it has the ring gear in a position that won't work in our gear boxes.and they are too wide
The tb03 gear diff can be a starting point, and a machinist can grind , shorten the whole unit, and relocate the ring gear to get it right.... Maybe a cnc machine can carve a new gear diff case with the new correct dimensions...

I am a machinist haha. But yes you can look at the tb03 for ideas. Has anyone tried the geardiff f on the apex tc?
The apex design is huge compared to the tb03.... I think a new cnc machined aluminum tb03 type gear diff with set screws to attach the tc4 ring gear(just like the spools) is the way to go....
