need for scater shield

I don't know, do you really need your feet?
Seriously, most clutch explosions are a direct result of shock loading and high RPM launches. Obviously most cars don't have scatter shields and get along just fine. Therfore, whether you need 1 or not depends on your intended use of the car. If you're going to drag race it, I would think that the additional safety factor and the the fact that you already have 1 would outweigh the hassle of using it.

Just my $.02
