$650 seems kinda expensive-- i bought my clear bra (3m) on ebay for 170 shipped and am getting it installed this saturday by a certified installer for 250. my kit is for the fa5 and includes the bumper, hood, fenders, and mirrors.
my advice: shop around and find a trusted (certified) installer and shop around for the clear bra.

on ebay:
eBay Motors: 2006 2007 2008 HONDA CIVIC SI GENUINE 3M CLEAR BRA (item 220091008259 end time Feb-03-08 14:58:57 PST)
this is an auction from the guy i bought from. make sure to email first to tell the seller exactly what car you have-- i had to clarify that i had an fa5 not just a 'regular' sedan (not sure if that truly matters but the seller said there are some differences in the kits).
hth.
