Advice required please, over the last winter I did a few cosmetic upgrades which included front and rear carbon arches, new black screen, windscreen brackets, FIA roll bar, carbon headlights and indicator pods. The reason for the thread is that when I get to 75 mph ish I get a noise which is becoming very difficult to locate. After several journeys removing something each time I think I've cracked it. I think the noise is from the flex in the front carbon arches at speed. Would it be possible to fibreglass the under side of the arches to stiffen them up and if so is that an easy task? Suggestions please.
