May as well paint your standard boot black for all the weight it'll save. Weighed a C/F boot against a standard boot and there wasn't much difference at all.
It's just form over function imo.
do you remember weights ? also did you get to weigh oem glass ?
I know a fella that has one for sale! It is £400 I think, second hand with a Mugen Spoiler in Jordan Yellow! He also sends to UK. He breaks Hondas and I think it's a real bargain.
Give me a shout and I'll pass on his details if your interested! Spoiler is genuine also!
