I did multiple searches to get an answer, and I cant seem to find one. Searched topics from "wheel offset, agressive wheel offsets of coupes, 20s on coupes, etc.." and I cant find an answer.

My question is, If I put 20s on a coupe dropped on Tanabe springs, what is the most agressive offset I can use in the rear without having to roll the fenders but still have an agressive stance. I want a fat lip on the rear and a decent lip on the front rims. and what offset should I look for on the front. And if you can suggest a proper wheel width for the offsets, I would appreciate it
