How to decide my wheel set up

Hey i got a 1994 Eg coupe. Im trying to get new rims for my car. I was looking into getting all black diamond racing rims. I dont care what people say about my choice of rim all i need is the knowledge on knowing how to achieve what i want. So what i want to achieve is jus dropped and flush. I dont want flush and tucked i dont want stance where my wheel looks like its about to fall off no matter how good it looks or how ugly personal preference applies. But i was looking and the info for ordering require fields to be filled would i be close with what i want to achieve with 15x8 4x100 bolt pattern and a +0 offset? The only thing that throws me off is the offset and im not sure if the 15x8 would actually stay flush or poke out too much, i dont mind some poke but i dont want to look retarded riding around. Anyone with genuine knowledge please lend me some assistance please thanks.
