failsafes are way way more important than upgrading suspension and bumpers and stuff. without a failsafe you run a pretty good risk of destroying any hopped up parts you put on your vehicle as it careens full throttle until it his something solid enough to stop it.
fail safe... no... if you want to run a stock radio then feel free to run a fail safe... or you can just get a new radio and you can be covered! thats what i did
