225/35 R18 won't fit
The minimum wheel width for these tyres is 7.5" and the JCW wheels are 18" x 7"
Only option in my opinion is 215/35 R18 as this is the most popular size. I wouldn't go for the 205/40 R18 as only know of 2 options, the OEM and a Micehlin, plus they're not cheap.
Plus 215/35 R18 don't rub even without the steering lock limiter
