Which kit?

Ordering part is a poorly made up justification. Rear brakes should last years.

I get the fact that rear discs are cool and getting them for that reason alone is fine. Hell I would like to have them my self.

Just don't expect much from them. Fiberglass front bumper and battery relocation to the trunk would be more effective toward your goal and about the same price.

I only say this stuff because your luck with some of your ideas hasn't been that great.
