993 Carrera 2 coupe - increased tyre sizes?

I have always felt that the wheel/tyre combo (front 205/50x17 and rear 255/40 x 17 - on Targa split rims) could do with 'filling out' the arches to a greater extent than at present. One option would be to fit spacers, but my local OPC would only countenance the fitting of Porsche 5mm spacers each side - which hardly seems worth the effort/expense of so doing, particularly when (by my own rough calculations) I think the front arches could take spacers of at least 25mm each side, and the rears a more modest 15mm.
 
The tyres will shortly need to be replaced and I was wondering whether I could do so with a "one size larger" set, ie 215/50 and 265/40 which would have some effect in filling the arches. I wouldn't want to lower the sidewall ratio. It is my understanding that the rims will easily cope with the larger tyres, and I don't believe that the resulting speedo error would be at all dramatic.
 
Do any 993 owners have any experience of what I am suggesting - and are there any other considerations (about which I am unaware) to watch out for, eg fouling of brake pipes etc?
 
I would also say that the car is driven 'sympathetically' on roads; I am extremely unlikely to venture near a racetrack - so the loads on the tyre will remain modest!
 
I'd be interested in your views.
 
Many thanks, John Dymond

John,
 
owning and driving a 993 for almost 20 years now, my experience is that you´ll pay a price for a wider track or wider tyres. The best and most comfortable combo on a car driven as you describe it is the factory standard. Especially wider fronts are a pain in the neck for road use. My car is lowered 20mm though (factory option) and that helps for a better look indeed - maybe that´s what you´re looking for?
 
Hope that helps.

Thanks Hacki - I appreciate your comments, borne out of your lengthy 993 experience. Your suggestion is definitely worth considering (shame I've very recently replaced all the stock suspension parts!!)
 
Cheers, John
