Pictures of trimmed fenders

I have it cut, it was done by my paintshop. Dont have picture now, will try it during weekend. But basically the inner lip is completely cut so there is just about 3-4 mm left.

 

Isn't it better to roll the fenders?

Rolling the fenders is the way to go. This doesn't require any cutting, eliminates the protruding inner lip of the fender and doesn't create any other sharp or uneven surfaces. Any competent body shop can do this in less than a day.

I had it done to my 360 and even with 19" wheels/tires, I never scraped once.

Here is what is used to do it:

roll them, go to a panel shop and pay 100 bux and get it done.

 

When there rolling them make sure they do it slow so the paint doesn't crack and heat up the fender's ever so slightly . It helps the fenders bend !!!

 

NO DONT ROLL!

The paint will crack,Ferrari paint is not the best quality anyway.

I reduced mines with Dremel disc and the metal files,I know it sound terrifying but you cant tell if you see them,the paint is perfect.

I was in the same situation to roll or to cut and Novitec GMBH told me to cut not roll,I had to cut around 5mm in 2 different scions first 3mm but I noticed I need more so the best is to let the wheels to rub a little bit this way you will know where to cut the fender and where to leave it alone or the pro one elevate the car and remove shocks and one side of the bars lift the suspension with the wheel and mark the fender with a marker.
The rear fenders have a 2 layer sheet metal so you have enought space to cut.

Remember this is a 2 step mod.
Scary but very cool....

 

I went to my paint/bodyshop to roll them, but they told me same thing as Luiscarlos mentioned - danger of crack. they said much better and clean solution will be cut so they did it. I am happy with result. However lot of guys roll them without problems - just someone must know what/how to do.

 

Use a hairdryer type of blower that is used for shrinkwrap tubing.

It concentrates the heat and will do a great job.

Also do the process when it's warm outside. it's easier than on a cold day or in a cold shop.

 

Cutting still leaves a sharp edge. Rolling does not, but has significant risk of paint cracking if paint is not properly warmed up.

Even with the Eastwood tool, rolling the fender lip is not easy as one might think as the aluminum lip is very hard, while the flat portion of the fender is quite flexible. If you exert to much force then fender arch may deform.

Either way, it's best to leave the work to professionals and cost is quite minimal.

FYI on all 360 Challenge race cars the fender lips are rolled like a U from Ferrari so no chance of cutting a tire. On all 430 Challenge cars the lips are NOT rolled. We sent ours to body shop and they heat the lip from inside. Some paint discoloration on the lip. Shop paint it flat black to keep it neat, but not visible from the outside anyways.

 

Really it is better to cut and use a file to smooth.
Sure FIA GT 430 come with rolled fenders so they can use a more aggressive wheel and suspension offset,I'm not sure but maybe those animals also use wider tires...

CUT don't ROLL,I have rolled several cars in my life and paint always finish coming off even if you use heater.In some cars rolling is the best way but in 430 cutting is the best.

 

you need to roll with a heat gun and no cracking at all.

 

Not much to see in the pics because you cant notice the mod the finish is perfect and you can touch with your fingers and the aluminum edge is smooth because i sand at the end so the tire rubber is 100% save.

 

Here is a picture from the 360 Challenge manual showing how and where the fender lip is rolled on the race car. The inset diagram dotted line shows lip of original fender. As you can see with a rolled lip, you end up with a flat surface. Rubbing a flat surface against the tire side wall is unlikely to cut it. If you only trim the fender lip, you do get more clearance, but there is still an edge which can cut into the tire side wall if rubbed up against it.

Unless you are using a wider tire, wheels with less offset, lowered the car, or less camber your stock 360 tires really should not be rubbing against the fender lip.

This is pretty standard stuff, my official Porsche garage has done it with my last 2 911's

 

A few years ago, I used an old baseball bat (after drinking too much Bordeaux) to help Fchatter "eclipse185" roll the fenders of his 360 Spider. It actually worked pretty well -- considering we were both a wee bit drunk and it was pretty damn dark in my driveway. Moral of the story? A Louisville Slugger does perform nicely on a Ferrari fender.

 

JIJIJI good story ,when i was young I rolled the fenders of a Jetta with a steel tube and I wasent drunk ijijijiji you can imagine all the paint !!!

 

Hmmm....alcohol, baseball bat, Ferrari....doesn't sound like a good mix...

 

I rolled my 993 rear fender lip with a short (about 2 foot) piece of broom handle. I found a recommended temperature (on a Audi forum) to heat the paint to. I used a laser/non contact temp reader to keep the temp within range. Using the car tire as a support and the broom handle, I was able to 'work' the lip up. If you have a friend to lend a hand, you can roll the car back and forth as you work the baseball bat or broom handle to fold the lip up. Go slow and you should not have a problem. Keeping the lip adds support to the fender edge and no sharp edges!!!!!

 

So any picture to illustrate how the fender cut should be done?

 

The short of it is this.....theres no difference the end result is the same. Its how you actually perform both which gives you the debate of which is better.

1-Rolling- If you are going to roll you need to either rent or buy a fender rolling tool which attaches to the hub OR something like a broom handle or baseball bat (something that isnt tapered is better though) WRAPPED in a TOWEL will work but requires MUCH more attention to detail. You NEED to warm the fenders and KEEP the fender warm throughout the whole deal ( have a buddy keep a hairdryer on the fender while you shape the inner lip up) if you dont ...well this is why people crack their paint end of story.

2-Cutting- Make sure you file or cut evenly not a whole lot to it but what most people neglect here is making the edge smooth. They leave sharp barbs or slivers of metal from their filing/cutting. On top of that most people forget that they just exposed bare metal on the edge. Either go get it painted or put some sort of rust protectant/paint on the newly exposed edge.

The looks are the same and the effects are the same...its just how you go about actually performing the work.
