ok i think i might have a problem. as i was reading the 2005 rulebook to check on roll bar requirements i noticed something about steering wheels that im not sure i understand. in the STS class, i noticed that i can use an aftemarket steering wheel of any diameter. cool. but then in like fine print it said something about airbags. do i need to have a steering wheel with an airbag? if so i think im ****ed...
