I just had the HFP Suspension installed on my Si yesterday. It is only a 0.8 inch drop and it should settle a bit over the next week. This drop maintains the factory warranty and is specifically designed for the Si. As far as handling is concerned, I haven't been able to test it out much because of the rain. However, initial turn in during lane changes is improved. The ride is definitely more rigid but livable. Here are a couple first day pics.

looks good

 

One of my friends has the HFP suspension on his civic and loves it, I haven't gone for a ride with him yet, but it seems like a great solution option and super easy installation.

 

But the limits of the car are easier to explore in the rain.

But seriously, I've said thats the way these sporty Hondas should've come in the first place. I have the A-Spec suspension installed on mine, and it's been a complete revelation -- understeer's been greatly reduced on very challenging roads.

 

Looks really good. I'm still considering a HFP setup for my 03 Accord 6mt. It's either that or Tein H-Techs/Tokico Blues.

How much did it run you?

 

There is one dealer who has phenomenal pricing, most have no clue what HFP is, I'll ask my friend where he got his from, he did a lot of research. I have to say it again, you just can't beat how easy the install is with HFP parts.

 

Looks good, one of my friends has that setup as well, except he also has the 18"? wheels

 

nice civic =)... and out of curiosity.. how fast are the civic si's?

 

Mid 6's 0-60 and probably mid to high 14's

I raced my friends on the highway a couple days ago and took him by a car. Its an 06 Si with an intake and exhaust.

 

Nice, should settle nicely.

 

$612 from College Hills Honda. $222 install at Honda of Bellevue.
