Hi Guys,

After lowering my car I notice once in awhile I'm getting a bit of tire fender rub on the front. My question: roll the fender or trim them? My body shop who are considered one of the best in the country for Porsche's is saying trim them in just the area that's hitting as opposed to rolling. Your guys opinion?

I rolled mine myself because I was told trimming them weakens the structural rigidity.

don't rim them. Weakens the area.

You can do a combination of both, I did 8 years ago-no issues. If you lose the existing flange via rolling, you still weaken them some.

If you don't fix it, and get sideways requiring opposite lock, the front loading will probably bend your lip down. Ask me how I know...

Most of the tire rub will occur when you are on the brakes and turn into a concrete driveway. The ramp will push the inner tire up and you will get pull out. The outer tire is turning inward, so it's actually better to leave the left fender un-rolled.

What I do is I press on the brakes as I approach the drive way, and turn in. Then right before I hit the driveway with the right side tire, let off the brakes. The car will raise up a few inches and you'll clear the driveway without hitting the fender with the tire. Same works with both front tires when crossing railroad tracks.

it takes 10 minutes a side with a wooden baseball bat to roll them. With some luck and a little patience, you won't get any paint chipping. Just don't use a bat that you don't want to chew up a bit...

Roll them. When you start to trim them (cut them) you are now disturbing the galvanized coating. Don't do it. The only fender that usually is a problem is the front left one, but do both to be sure. Just be patient and work slowly a half inch at a time.

Thanks Guys. I worry about cracking the paint

+1 on the wooden ball bat.

Here are some discreetly modified fender lips in the GT350 I used to race. These were not done with a baseball bat - they were done with a pile of money at a master restorers shop!

Mine is going to a restoration shop that I have used before, and they are going to do it on this coming wednesday, wish me luck.

I raised the front end back. Spend your money on tires, track time or schools if you want to be fast.

What does this have to do with fender rolling? Nothing was stated about going faster.

Mine were rolled but I also got rubbing in the INSIDE with the tire hitting the gas overflow and A/C hoses and the bracket that holds them to the body. After several attemps to first zip tie the hoses up higher into the fender , I ended up using the upper bracket (there are an upper and lower) to hold the lower hose and zip tied the top hose to it . Now, no rubbing.

Why else would you want to lower the car.
