There is no 94-98 replica of the lemans wheel.
The offset on the real ones are 10 and 30mm. 8.5 wide.
Those would likely be your best bet, but you will probably need 4 of the same offset and even worse 4 identical wheels (while they look alike, there are 4 versions)
IMO, change the axles and the brake brackets.
I know it sounds like a lot of work, but it's not.
