Why? The spacers are for lowering the amount of backspacing you have and for pushing your wheels further out from your inner wells and suspension components. You already said that the wheels have 4.25 of backspacing, so that isn't your problem. If you were to add some spidertrax spacers, that would take your backspacing down to 2.75" and the wheels/tires would stick WAY too far outside your fenders.
Now, if it is one of the spokes or another part of the front part of the wheel that is making contact with the spacer, then I reckon a spacer could fix that, but you would only need a very small spacer.
Really need to know what part of the wheel is making contact with the caliper; part of the wheel face hitting the front part of the caliper, or the wheel ring hitting the side of the caliper.
Here is a pic of someone running the 16" 997s and 35s without spacers (to my knowledge), so it can be done.
