in comp4 are you requaired to run fenderliners or no

 

I have not read anything about fenderliners being required.

 

because my best friend is doing scca autox nationaly this year and he has a 89 civic hatch si and he needs them so i was going to give him mine of my comp4 crx and it says in rulebook about the fenders being trimmed up to an inch i didnt know if that was fenders or liners thanks guys
