Several weeks ago I ordered a Eastwood Fender Lip Roller. I decided to spend the extra money and do it without cracking or chipping my paint. It bolts right onto your drum/rotor with your own lug nuts. I used a heat gun to soften the paint while we rolled the fenders. We started out rolling slowly, making small adjustments outward on the arm. The rear quarters did not want to roll due to the outer wheelhouse lip and the quarter lip being together. Having the two pieces of sheetmetal together made it impossible. I had to notch the lip and then it rolled. I rolled the lips flat up against the inside of the quarters giving me as much room as possible. The fronts are a different story. Being only one layer of sheetmetal, it was much easier.
Overall the job took the two of us 1hr. It took a lot of muscle to roll the arm back and forth for the rears. The fronts were easy but you have to keep the steering wheel from turning. The quality tool is very heavy duty even though it is made in China. I wish I had done this several years ago before I sliced and diced my present tires. I can now run the 295s I have been wanting to get. The rear end in my car is a little wider than the stock 8" that it came with.
I was able to determine the correct backspace and max width with another tool I purchased called Wheelrite. It is a wheel and tire simulator. They have a web site and there are videos out there showing you how to use this tool. You can determine what your max wheel width, tire profile, and max backspacing can be.
Here's a pictorial showing the Eastwood Fender Lip Roller
We first started with the rear quarter panel lips. After you set the fender lip roller up, soften the paint around the fender well with your heat gun. As we started we soon figured out that the two layers or sheetmetal didn't want to budge. We rolled it back and forth adjusting the arm outward and the lip just sprung back. I made small notches in the lips and that made the difference. I only made the notches where I wanted the lips rolled.
This pic show lip rolling process half done. Make sure you keep the paint heated if it is taking a long time. Be careful not to burn your paint. These heat guns get extremely hot.
Finished quarter panel. The lip is rolled completely up against the back side.
The fronts are very easy. Only one layer of sheetmetal to deal with here. No need to notch the front fender lips.
Adjusting the tool.
Here is a picture of the passenger side completely rolled.
This is the Wheelrite tool I mentioned. I was able to determine my maximum backspace and wheel width I can use. I used the profile of a 295 tire in the shop to form the contour of the wire on the tool. Here is a link on how this tool is used.
