With any spacer, I'd strongly advise you get hub-centric ones. It seems that BORA is one of the higher recommended brands. I have no personal experience with them or any other brands other than the ones I had. I ran these for about a year with no issues at all, and I drive aggressively:

They've gone up $10 since then. My brother has had them on his Sierra for about a year now. He drives like an ass, tows a trailer to the camp, etc. and hasn't had any issues, either.
For the aesthetics, I'd recommend you get 1/2" wider ones for the rear than you get for the front. Also, with the 1.5" ones, you may need to trim the excess, unthreaded tips off the lug studs. It will depend on how the mounting surface of your wheels are made. Wider spacers may minimize or eliminate this necessity.
