You can save yourself a lot of headaches and/or tire damage if you are ready in advance for the side effects of going lower and wider. The number one obstacle can often be those pesky fender lips. If you reach your hand under the arch of your fender you will typically feel a lip at a 90 degree angle to the arch that can protrude into the fenderwell by an inch or more. This extra material is there to add structural rigidity to the fender arch. If the effects of lowering and widening your car causes interference with this pesky little strip of metal, have no fear, I have the answer.
The Tire Rack Fender Lip Rolling Tool is a professional quality tool designed to maximize the wheel well clearance when upgrading to larger tires with lower positive offset wheels. The tool can also be used to repair the wheel well area and lip damage.
The Tire Rack Fender Lip Rolling Tool fits all four and five-lug wheel hubs up to 120mm bolt circle with hubs up to 72.5mm, however it will not fit Porsche. The forming arm adjusts from 14" to 22.75" to roll lips almost flat. The plastic coated (Delrin®) roller forms the fender lip without damaging the paint. In addition, using a high temp hair dryer or heat gun with the Fender Lip Rolling Tool will minimize the potential for paint damage during use.
