HFP Suspension Review

[MutantCheese]

Mine rides like a rock. Very stiff, but I like it that way.

It is just a tad over an inch lower but that is plenty especially if you live like me in areas with a lot of uneven roads and chuck holes

Where did you find just the springs?

Here on the forum. BlueRocket bought the HFP Suspension kit but wanted
more of a drop then the HFP springs provided so he bought some other type of springs and sold me the HFP Springs from the kit. Those springs are GREAT
and not as agressive as some others out there.

Has anyone put these on a SI Sedan?

Most of the Auto-x and Road race guys will tell you that dropped cars without proper matching shocks and struts will make handling worse not better.

LOVE the new wheels BTW. How much do they weigh each?

if the drop is only another .1 or .2 inches lower, the hfp shocks should be fine.

Should be, I agree.

[unplugged]

but the spring rates also have an effect on the shocks, so who knows

i found the HFP for 510 shipped. I might sell the HFP springs and put the progress on them.

care to share info? or is it a single purchase....if u wanna help a fellow member out, pm me where your ordering from, hopefully they go to canada

[g$$]

how does the hfp suspension handle weight in the back (extra passengers, stuff in trunk, etc). will the rear sag low like how the stock suspension does? yes i've read the setup is stiffer, but i'm just double checking.

Exactly what I was thinking! I took a trip to Tennessee last week and couldn't get enough of the roads there, I think I went through about 3 or 4 tanks of gas in a week just driving up and down the mountains. I want to move out of this BORING place called Louisiana...

My car is getting the HFP kit right now. Dealer quoted $475 to install...

[07CaliSi]

I got mine installed for $250 plus $100 for alignment.

[packers04]

100 dollars for alignment? wtf?

Around here it's 100 dollars too.

It just depends on where you live and what price they set it at.

[packers04]

darn. yeah hawaii is expensive. i paid 40 for 4 wheel alignment at the dealer.

By a dealer?

[hyciv08]

how would or what is your opinion on an hfp kit for the HCHII?

[bentbeat]

i just got my hfp and installation for 700 total. friggin car rides A LOT stiffer. didnt notice it at first, but after i went over a couple of bumps and especially speed bumps, i could feel the difference. my friend who is running a koni/ground control coilover kit on his e36 told me my car felt like his car at near full stiff. as for handling there is a difference that i can definitely feel. i am running yokohama s.drive at 225/45/17 and when i take turns i can now actually feel the tires gripping instead of my entire body rolling. in other words, there is a better feel on my steering wheel as well as feeling of connection to the road. the backstreets i usually have to drive on when i go home is where i currently just tested my car on and my car definitely feels and corners with a lot more ease.
as far as looks go, the car definitely got lowered since the gap is now 2 finger gaps, while before it was 3. dont really see it though.
so in closing. id say this kit is great if you dont have the cash to get adjustable or are waiting for more options ('cough' KONI) to come out. but be warned. this suspension is really unforgiving. if you go over bumps a lot or have roads that have a lot of uneven or bumpy areas get ready to test your body. because it seems to me this suspension just make you feel all of it.
will update next week when i get my progress sway bar with new brackets and volk ce28n's in.
wonder how much lighter wheels can do for me.

On my phone and the search button doesn't work, so what exactly must be done for the warranty to not be voided? Does it need to be purchased at the dealer or just installed there?
