the title say it all, I would like to know if adding to the Storm R a front screen from the GT is useless, or does it offer a better protection (even if limited due to its size) on the highway?
I think you might be better off with a larger aftermarket screen for highway wind protection. The GT "screen" is hardly anything. Depending on your height, it might even dump wind into your face, making it worse than clean air. I found with windscreens its pretty much all or nothing.
