I'm a new 964 C4 cab (and new Porsche) owner. Love the car.

Am about to fit a set of 17" 55 offset cup II wheels to the car with 225's on the front. I've read Adrian's book and read tons of articles about this. I have 5mm spacers (couldn't find 3mm anywhere) and the 10mm steerings stops on the way.

The book and forum posts also mention grinding a bracket on the 1990 cars to prevent rub. Can anyone please describe in detail where this bracket is located? Or better yet, maybe some pics?

I can't find the technical service bulletin anywhere. Does anyone have it or know where I can get it?

Thanks in advance!

It is at the outer front edge of the wheelwell where the fender meets the body.

Marc - can't thank you enough. This super helpful.

Cheers.

Yup, once the fender lip is rolled this sticks out in a sharp point. It's the same on my 3.2.

Can someone describe exactly what fender rolling is and how it is done. I think I know but want to get a clarification.
Thanks.

Looked at it last eve - seems only about 1/4" or so could be ground off that bracket, otherwise you'd risk weakening the fastener there.

Sound about right?
