Do 15x10 rear Billet Specialties fit

[LOW MILE SS]

Looking to buy street lite wheels 15x10 rear. The question is will they fit w/out caliper mods/grinding. I have gotten different opinions on this from dealers and manufacturer. I am looking to keep the factory brakes for know and some say only ls1 brakes have problems fitting others say both will have problems. Looking to possibly narrow the rear 2 inches and use 5.50 inch back spacing. Should i be o.k

I know this is an older post but here the deal on my car...rear narrowed 2" per side...15x10 BS Street Lites fit no problem. I did do a little ginding since I have some rubbing down the road, not sure why since nothing changed, might have been a rock or something. No well issues at all.
