The red ones I bought are the same as the black ones.

From thier page.
Prothane makes parts in 2 colors. Red and Black.

How are these two colors different?

Aside from the actual color, the red parts are essentially the same as the black.

I thought that the RED parts were harder and more performance oriented?

This is a common misconception. The red parts have the same durometer (hardness) as the Black parts and differ only in their actual appearance (color).
