How much spoiler is too much??

[35racing]

could a 12" spoiler on a half mile track be to much and cause more drag than its worth??

was running 8" spoiler with spec engine,

Now going with steel head 360 with 12" spoiler no weight limit, and a 6" x 36" front air foil.

not sure if that much spoiler will help or hurt speed??

Height alone isn't as important as angle combined with height.
