If you want to spice up your USDM Honda Civic but prefer not to be splashing your money on the exclusivity that the MUGEN Honda Civic Si Sedan gives you, perhaps you should take a look at Honda’s HFP Civic Si Sedan. basically a similiar deal – a 2007 Honda Civic Si Sedan kitted out with Honda Factory Performance (HFP) parts.
You get performance springs which lower the car by an inch, larger wheels with the same tyre size as the MUGEN Civic, a chrome sports muffler, and a bodykit. The HFP kit will cost US$3,800 with installation.
BTW, notice that the US market tastes do not particularly favor foglamps on the front bumpers. An example of how cars have to be localized to suit different needs.
