In order to run these, you will at the minimum have to run a SN95 brake conversion on the front. The standard drum conversion for the rear will work just fine. For this, we recommend part number SVE-2300EK. If you elect to do this, give us a call at 866-507-3786 and one of our customer care reps can get you fixed up. On a fox, we recommend a 275/40/17 on the rear, and 255/40/17 on the front, so we can swap those out for you to make this fit appropriately.
