They [dynamique alloys] will fit fine, will just clear standard brakes and have a standard clio offset. I have them on my 182 right now (for winter tyres).
Thing is, as you probably know, 888's are quite wide, slightly wider for a given size than regular UHP road tyres, and whilst they will be quite happy to sit on a 6" wide rim, you might think they look a little "ballooned", couldn't say with any certaintly how that will affect their performance (over, say a 6.5 or 7inch rim, which is more typical of track focussed cars), but that's for you to decide really.
Also, at ET43 it will look narrow-tracked with them and, I coudn't care less what my car looked like if it drove how I wanted, but you may feel that you are missing out on a bit of width with the offset at that.
Like I say, just things to know about and consider.
