Pescara's won't fit over a BBK without spacers. If you get them, you'll need to gain at least 5mm so go with 8mm and get some Hubcentric ones and longer bolts, should be ok then.
Or get some BBS VZ's. Look like Pescara's but with a wider rim and better offset, 18x8" ET44. I have these on my Eddy and have loads of room, 13mm to be precise (without spacers) for my Porsche Brembo Calipers.
I still have at least 7-9mm clearance.....
