Congratulations, your car looks very nice!
You seem to have made a wise decision choosing 185 mm tyres instead of 195s, saving you from modifications to the rear arches.
My R9 used to wear 7 x 15 ET 36 steel wheels (original Clio Cup wheels) with 195/50R15 tyres, and I couldn't take rear passengers or much luggage, otherwise the rear tyres scrubbed against the body. One centimeter doesn't seem much, but in an R9 (or a 5-door R11) it makes all the difference at the rear.
However, even if my Sava tyres (yeah, I was broke back then... Well, still am, actually...) were marked 195/50R15, I measured the tread surface to be 215 mm wide! In fact they were actually wider than the 205/40R17 I later bought for my R19...
Speaking of 17-inchers, I currently have my R9 on 17s! My 9 is finally for sale (bought a '00 Twingo...), and I wanted to make this one last experiment I'd always dreamt of doing, before my 9 and I part company. Which will be kind of a sad moment, I'm afraid.
I too will post pictures of my car in its current state quite soon(ish).
