Help me complete my build.

A cage for your own safety,maybe a harness too.

mini-tub
bigger tires(slicks)
Hey you asked.LOL

Cage is going in for sure before I even think about hitting track.. I'm still debating on tranny.. so I don't currently have a DS picked.. I'd like to get the largest size tires as possible.. it would be cool to run this car in a true street class or at drag week where I have to drive the car from track to track 5 tracks in 5 days.
