The summit kit is made out of plastic, and is very inexpensive and not NHRA legal. The battery relocation kit that I have in my Mustang is from Cartech. It is a high quality aluminum box with a bar acrossed the top, just under the case's cover that you bolt on to keep the battery from moving around. I did not have to relocate my solenoid either.
