Just Did This!!!
Minimum offset is 30mm, and 35mm is better. With some tires, on severe compression with 30mm, you may have slightest of rubbing on the inside, vertical wall of your inner fender.
185/70R14 is as much as you need for most applications. It works quite well with stock suspension, and really enhances a sporterized suspension.
I'm running Bilstein shocks, IAP performance springs, a stock front sway bar, and a stock rear sway bar from a GT... which required my adding mounting points on the body... and getting the entire bolt set up for the trailing arms. I replaced bushings throughout, and stayed with the rubber ones, rather than the firmer poly ones.
Lovely set up for the street.
AND, if you haven't purchased your tires yet, chase down a set of Vredestein Hi-Tracs in 185/70R14... they're H rated, and really offer great feedback, and with their sidewall construction, make for a very compliant and comfortable ride... consistent overall performance winners in their category in UK tests the last 3 years. Great, great tires.
