The cars you have look like the F103 and F103L. These use the same fitment as the 3racing F109, so all wheels designed for this range of cars will work (the F104 ones wont fit).
The indycar wheels are a larger diameter, so these will need Pro10/GT10 donuts instead.
For F1 wheels and/or donuts, give FTD Models a ring (
