Where did you buy it & how long is it?
I bought 1 as well, only 50" (127cm)
too narrow 4 my fat ass R33 :S
took out the old spoiler and yeah I know what you're saying
although I think it'd look a lil better with the stealth/duck wing
there's 1 on some eBay store selling for $239
if you ask me that's a rip-off for small piece of plastic/fireglass
because after I took the spoiler off, I noticed the boot slants downwards
and doesn't align with the rear body.
plus got shit loads of holes you need 2 cover up
here's some pics of mine without the spoiler
