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.

certified cage required if you run 9.99 or 135 mph...

roll bar required if you run 11.49 and faster....roll bar is good down to 9.99 as above if you have stock firewall and floor pan..not including wheel tubs...
