Long time coming, but I'm building a little bracket car

Cage isn't a real problem, 2 of my good friends build race cars for a living and I have a Miller 35 mig welder so even welding it myself would be OK. Do you have to have a cage certified if your running those times? Hey pettybluedart, do you race at Grand Bend? I have a buddy named Brighton who races there.
Yes I race at..
Grand Bend
St.Thomas
Cayuga
Snannonville
This year I beleive there is 2 new tracks opening.One near Ottawa and one near North Bay.Yet to hear about opening dates though.What type of car does your friend race?

Sorry for Hi-jacking
