i just passed the pits and had to get permits for strut bar, pod, sports exaughst. (without a cat hahaha but they didnt know that) and frontmount. but my reo bar is still in. and even for the boost gauge and steering wheel. had to change park lights head lights. get horn rewired, take out flamethrower kit.
so yeh theyl check everything.. not to sound bad but expect the worst... at least that way you wont be suprised if they nail you. but in saying that the first time i took a skyline over the pits they didnt check everything. but the last time i went over thay did.
