Wheel gaps

Should the wheel gaps be the same, front vs rear or is it better to have more gap on the dfw?

Perfect timing with his question. I too was wondering about wheel gap. I am more curious as to the method that you use when approaching what wheel gap that you use. Do you have a set gap? Or do you test before/after each change, do you change gap on only one wheel at a time, or maybe one end of the car at a time?????

I guess I am just wondering how to systematically approach the best way to determine how to set wheel gaps?

Again, not looking for anyone's secrets, rather just a nudge in the right direction. ;) THANKS!!!

I'm pretty confident .015 is the way to go in the rears. It has been posted by multiple reputable racers! Just curious if a more relaxed steering gap would be better. My thought is that it would allow less rub on the outer hub.
