My vehicle came equipped from the factory with the speedster hump option. I hated everything about them. Indeed, the way they looked, the fact that it was really a two person job to safely put them on and take them off, I couldn't operate the top while they were on ect.. I sold mine soon after getting the vehicle. Interestingly, despite the fact that the humps were speed yellow and in pristine condition, the person who purchased them had a black boxster .
