Design Drafter / Racer
Forgive my ignorance, but why add calcium at all? Why go to the extra hassle and create a lot of rust issues too? What does the reduction in lap times get you, other than follow the leader racing with no margin for driving errors? I'd think an 11 sec. track with wide natural dirt / clay groove beats a rubbered up single groove dirtphalt track? And far less hassle.... what am I missing?
