Sorry let me clarify...
I'm aware the spoiler is different from the normal SS/ZL1 spoiler
Al O. Said in the Leno interview there is a 'wicker bill' that attaches to the z/28 spoiler for increased downforce on certain tracks. Since it kinda looks like the spoiler on this z/28 looks a bit taller than the normal z/28 spoiler, I'm wondering if this z/28 has said attachment.
I'm picturing something like the spoiler on the zl1 carbon edition
