Thanks madjack, a short while after i posted i figured out that i could do this and felt like a bit of a tool. I came backto see if anyone had replied though because i wasnt sure that this would run OK, but after reading your post i tried it and it seems to be OK.

Thanks again!

I've had time to do some more extensive testing now and the F104 is super dialed!

The rear is made softer back&forth due to some modifications of the T-bar and the pivot pod (I'll post pics and a setup sheet).

the car is totaly planted with kit tires without tire additives. Next week I will try a 8.5 Xcelorin - hopefully I can post a video as well.

Default Silly question

But does the F201 tires fit on the F104 rims? Im mostly looking at them for display, not running.

It would be nice if Tamiya would make some to fit the F104s and 103s....

F104 are foam rims - smooth with no ridges for mounting rubber. So that's a no.

And I also assume that the 201 rims wont fit F103/4 series cars either?

F201 rims have hexes front and rear. So the fronts would be the problem.

Default TRG wheel dimensions

Hopefully this will help someone. If not, let me know what measurements you need

Ooops - and dimensions are mm.

King pin measures 33.4mm, you would have to shim the steering arm perfextly in the center of the kingpin to have it work, leaving no adjustment for ride height.

Do you have the wheel and the F104 handy to see how big of a spacer you would need to move the wheel out far enough out on the spindle to clear the kingpin?

I ordered a complete set of TRG wheels/tires today from RC Mart, I don't expect to have them for a week or so. I am determined to make this work somehow.

Looks like you need around 6mm to push it out far enough to clear the kingpin and the c-clip. Unfortunately, this means the axle is too short for the bearings (particularly the outer one) to ride on.

Longer front axle, anyone?

Phil.

Yeah, that is what I was thinking. When my tires get here I'm on it.

What is the diameter difference between the TRG rubber tire and the foam F104 tire?

Outer diameter of the TRG rubber front is about 56mm. Somewhat less than the 59mm foams on there at the moment (done a day's racing), but more than the well worn set of foams.
