If it is only a slight contact between the BRS and the tyre I wouldn't worry. It only happens when the stering wheel is on full lock, and that hardly occurs driving on the road. You should be able to hear it (when parking etc) and thus avoiding the last cm of turning the wheel. But I know people that have overcome the problem by putting some washers between the ower end of the BRS and the chassis, so to lift the BRS a few mm up and away from the tyre. And some have also put the BRS in a vice, then thightened the vice to flatten the BRS slightly where it touches the tyre. As for removing it; did you notice any difference putting them on? If not, you might as well remove. I did notice improvement when I put them onto my Roadster (luckily no chafing), but the difference was subtle, calming the front end down - as a matter of fact most of the time, not only braking
