Hello. I paid to have a new Gahh top installed on my 98 Z3 M Roadster. From outside the car, I noticed two bumps on either side above the rear window. I discovered that the top of the roll bars were in contact with the top, which was creating the bumps visible on the material outside the car. My factory top was in such bad shape when I acquired the car, that I do not know if what I'm seeing is normal. I would have expected that the top would clear the roll bars without touching them. I appreciate any information you can provide. Thanks.
