I have just read this lengthy but very informative article & appreciate all I've learnt so I thought I would add my details & setup in case it gives someone a perspective they're looking for. This is my machine, and it is on its original wheels 19 x 9 ET35 which I believe is the European set up even though I'm way down in the antipodes, Christchurch, New Zealand which just below & to the right of Australia in case your wondering,... think All Blacks, Rugby, & the Haka etc. I have had the failed DRC replaced with Bilstein adjustables so that allows me to set the ride height how i like it, which is quite low compared to some others I see here. The only issue I've got is slight rub on inside of front guards when turning full lock, but no issues any other time even when driving to the limit on tight winding hills. I to was wanting to change my wheels & have been wanting a very nice set of RC10 Rohanna's from the USA as I'm very keen on a very deep dish look with wheels set to the outer edge of the guards. I was almost going to risk 20" but this article has convinced me to stick with 19 x 9.5 with a ET31. I hadn't realised the ride & drivability compromise, this car needs every bit of help it can get to go around corners at pace. Not sure when budget will allow this but once complete I'll post some pic's.
