is needed between the wheel and brake caliper? The area I am concerned about is between the back face center of the wheel and the front face of the brake caliper.

The reason is.....I recently purchased a used set of Procomp 15x10 Series 98 wheels, with 3.75" backspacing. I did research here prior to purchase and found a few guys running the same setup. I test fit the wheels prior to purchase and did not have any rubbing issues on the front or rear. But I noticed the space between the inside of the wheel and the front caliper is rather close. Since I had no rubbing and got a good deal on them I went ahead and bought the wheels.

Now I'm wondering how much space should be between the wheel and the caliper? I can put a wheel back on and try and get a measurement but I was just curious if anyone knew off hand.

Thanks

 

if is not rubbing you are fine

 

This is a topic of debate.

There is one faction that believes that it is OK to grind down the caliper edges to make the wheel fit with almost absolute minimum clearance, while there are others that believe that this is a bad practice due to potential interference and cooling issues.

It really depends on your tolerance for risk.

The smallest factory wheel is 16" so that gives you a starting point since Jeep has to carry the liability on this type of decision.

 

These fit without any grinding. Around the caliber and rotor clearance is fine. I'm comfortable on that end.

My concern is the space between the wheel face and the caliper arm closest to you. (I should have taken a pic.) But if you take the wheel off and are looking at the caliper, the little front arm part of the caliper facing you is where clearance is tight.
