Default OZ Challenge 18” 11j rear

I am considering to install then following wheels:

front 18” 8,5J ET 50 which I am sure it fits perfectly
rear 18” 11J ET 63 that I am not sure at all it would fit

1 inch (or 2,54 cm) more, split in two parts, 1,07cm in the inner side and 1,47cm in the outer part...now I have 7mm spacers with 18 inch ET65, but I think the only way it can fit the wheel compartment is adding some camber, isn’t it?

I think this might be the wheel set installed on the CUP car, with 235/40 in the front and 275/35 in the rear

front is fine rears not so much, the 10ET65 w/ 265 has a very limited amount of backspace room especially on the passenger side, a 285/30 x18 on that wheel barely fits w/ some lip work

For future use
on the left is what many of use on a lowered track type n/b 993 on the right is what a 993Cup would have used, tyres for the Cup would have been racing slicks equivalent modern Hi Perf rubber is used for both
