i installed some 285 michellin pilot sport cups on the rear of my 993 and I'm getting some ocassional rubbing. does anyone have any suggestions?

i imagine i will have to roll my fenders. has anyone done this? any good DIY? i really don't want to crack my paint so some good instruction would be very valuable.

thanks in advance.

cheers,
boris

 

Boris, I have done some of my front fender rolling myself but had the rear fender done professionally. It turned out very well in both cases. I used a broom handle and rolled the car with the handle against the tire slowly working the inner fender lip up and under. You need to to do this very gradually. Be very patient!

 

From audi forums. Rob used to let people borrow it for FREE.
It costs about $500

Gerry that is one nice tool!!

Boris just wondering what suspention your running? I have 285's on 18" & H&R's with out any rubbing!

 

i have 285's with koni adj shocks & H&R springs with -2 degrees of camber. more specifically i have michellin pilot sport cups.

 

Strange !! I have the pilot sports, just not the cup!! Things that make you go Hmmm!

 

Guys, since these cars are hand built, there can be variations from one car to the next.

Boris, if you insist on a 285 in the rear, roll your fenders with the TechArt tool or one like the one above. Another option (expensive) would be new wheels with a different offset in the rear.

 

Use the TechArt tool if a shop in your area has one...my green cab was done with this tool and it turned out pretty good. But if you don't have access to it you can still use the old baseball bat method which I used on my white cab a few years back.

Get a wooden baseball bat and cut off the ***. You need to heat the paint on your fenders so it doesn't crack...the times I've done it I've used a high wattage hairdryer and a butane torch - gotta be very careful with the torch - you don't need the torch, the hairdryer will be adequate if it is high wattage. You want to heat up the paint so that it will be as flexible as possilble...err on the side of too flexible rather than less.

Using the small end of the bat wedge it between the tire and the front end of the fender and apply pressure towards the tire...you will feel the fender lip bend a bit. Don't bend it all the way back yet...what you want to do is now roll the car forward so the bat will roll backwards towards the rear of the fender...remember to continue to apply pressure and you will feel/see the fender lip rolling inwards. Repeat several times, each time making sure to keep the paint warm/soft/hot and gradually bending the fender...you should use many passes rather than just on aggressive try. If you do it correctly the paint will not crack....I have to say though that it was one of the scariest things I've ever done to a $50K+ car.

Good luck!

As I remember I used a length of 1/2" pipe for my rear fenders. Car stayed stationary and I pried between the inner fender and tire surface. Lots of short quick moderate pressure jabs slowly working back & forth along the fender lip, constantly checking the job with my fingertips.

 

Boris - are you sure the rubbing is on the fender lips? You should be able to see paint rubbed off there if this is where they are rubbing. If you do need to roll the fenders I am told that warming the paint in the area to be rolled is a good idea to minimize the possibility of cracking.
