how do you disable the air bags in our cars?do you just pull the fuses and thats it?just so you know im doing this for(my first)HPDE 1 and im using a full face helmet.And from what i've been reading lately the FIA found that a fullface can cuase damage to your face which i cannot afford

yeah, pulling the fuses works. can't remember now if they are in fuse blocks or on the floor by the pedals.
Also works to annihilate the crappy ABS systems

ah thank you,i didn't even think about the ABS.

is there anything else i should do to get ready for an OT event?other than checking/changing all fuilds?

to disable the abs,do i take the relay out and/or one or both fuse's?

According to the shop manual I've used, you need to remove the fuses and unplug both driver and passenger side connectors (the yellow ones with the blue safety).
