[Thorp Optima-ultima Gear Sets (differences?)]

Great info , I just picked up an Ultima underdrive gearbox & diff complete with UJ driveshafts (thanks Dave) .This diff appears to be a fixed drive like an original Brat (locked? or is it made like this) I haven't opened it up yet

you may have already figured this one out already since I just found this ...

It's a ball type differential, but I just had it set pretty stiff. Once you've ripped into the case and pop the diff open you'll see. If I recall correctly I had the underdrive set in the case.

No problem, glad you could put it all to use.

[Ninja Wheel Size]

Hi all, it's been asked but apparently never answered .... does anyone know the wheel size of the Marui Fr/Rr wheels for a Ninja?

I've currently got Kyosho hexes on my Ninja and running Low Pro 2.2" wheels/tires, but I'd rather throw the original wheels and some replacemnet tires on the old girl.

Thanks

Dave
