Compatibility between F103 vs GroupC wheels

Recommended Posts

Hi, I am a bit confused... 

Is there any difference despite the number of spokes between those two sets of rims ? 

Any off-set difference or diameter / width? 

I want to use them on an F103 chassis and I know the 50442 is supposed to be the one, but I am building a custom Mclaren MP4/4 and the real thing had 6 spokes rims looking much closer to the 50399 set, used in Group C cars like de Sauber C11. 

I understand both take 45mm width sponge/foam tires right? 

In some pictures the Foams on group C kits look narrower than F1 kits..  I know the fronts a 30mm instead of 32mm ,but what about the back ones? 

Thanx!

@esmuz

The group C rear wheels mount to the axle using two press nuts and screws rather than the F103 single 4mm nut.

The width is the same at 45mm but the grp C wheel is a larger diameter at 45mm as apposed to the 36mm F103.

I have both sets of wheels with tyres fitted if you like a picture?

F103 on the left grp C on the right

The f103 wheel hasn't got the push in spoke centre's in as it's a P34 Tyrell

Thank you so much this is a great help!

So then I guess the tyres must be different too right?

Or does people stretch them to fit in the GR.C wheel? 

BTW in your picture the GR.C looks bigger in total diameter (rim+tyres) is that a visual effect? A fas as I know F103 wheels are something like 60mm total diameter.. how much is the GR.C?

Group C total diameter is 65mm,  so not much bigger but it has a lower profile tyre than the f103. Can't see how a F1 tyre would stretch onto a grp c wheel but I've never tried.
