Has anyone had any rubbing problems with this config: 245/45ZR16 with 2" drop K sport springs??

 

I am running 245/35/17 with 35 offset with a 2.2' d2 drop. The only issue I had was hitting large bumps and fast turns the underside of the fenders would rub. But you should be fine with 16" and 40+ offset.

 

I run 245s and I'm more like 2.5-2.75" drop, without rubbing. it depends on your offset more than anything.

 

by off set you mean bolting the stock rims back onto the stock hub without any spacers, right?

 

NO. offset refers to the distance between the centerline of the rim and the mounting face of the wheel. The term basically and literally means, the distance by which the mounting surface of the wheel is 'off set' from the wheel's centerline. here's a cheatsheet:

i was running 245/45/18 on a 8.5" wide wheel with some minimal rubbing..
