Default Function and form type 1, need adjusting advice

Well when i bought these coilovers, i had read alot of good reviews and didnt see any bad, i guess i didnt search deep enough, because what i heard for libertariat they are crap. But its too late now, maybe next year ill buy new ones. Anyway, they are very stiff (too me), keep in mind this is my second car, first honda, and first car i have actually dumped money into. So ive gotten a late start on learning what good companies are from trash companies to trash companies that are marketed well and kids with zero knowledge thinking they know what they are talking about. Is there a guide for adjusting the soft/stiffness of these coilovers, i will be lowering them about half an inch, and adjusting the softness (oklahoma roads are ****) friday when i swap my engine and rack&pinion. Advice from someone who has done this and knows what they are doing will be greatly rewarded

There is no real way to adjust spring rate, but you will want the coilovers adjusted high enough to allow good shock travel and prevent hitting the bump stops. Not sure of your tires, but a higher profile sidewall and air pressure adjustment can offer some tooth rattling relief on a lowered suspension.

Sadly there is not a lot you can do that I am aware of except fine tune the hieght and air pressure adjustment. Maybe someone else can chime in with more info

Well its already at stock height maybe a half an inch higger. It gets bad enough going to work that i almost lose control going over a bridge, and it drops, causing me to dip and almost get air, my question is why would they lable them as "street coilovers"?

Ask their marketing department. What spring rates did you purchase them with?

Im not sure it was 2 or 3 months ago, but i hvent driven it but maybe 2 weeks out of tht time, hoping they would soften and break in. I purchased them through a vendor on the marketplace of ht. And also im running 15x7 rota slips with 205/50/15 i think, the car is at a friends shop right now

Springs do not "break in". If they change rate, at all, they're trash and in need of replacement.

You can adjust the shock settings to your heart's content, but it will not change how stiff the suspension is (which is determined by the spring rates). All you can change is the damping, and both an under damped car and an over damped car can cause loss of control over uneven pavement, as can excessively stiff springs.

Sounds like you chose the wrong spring rates for your needs and local roads, or have the shocks very incorrectly set.

Well can i change the springs or am i totally ****ed? I was told progress is good for daily drivers, eventually i will get good coilovers next year but until then im trying to get by, so what im asking is if i cant change springs would i be in the same boat with some progress coilovers?

Need to find out what spring rate you have. And the drivability issues you're having with them indicate, to me, that something else may be wrong with your setup.

We really need a facepalm emoticon.

Stiff is the spring rates. Bouncy is an under damped suspension. You cure bouncy by turning the shocks stiffer.

And 10k (assuming you actually mean kg/mm) is 560 lbs/in, that is very stiff for a street car.

bouncey to absorb some of the stiffness could be perceived as comfort... might be appealing to some :D

That's the reason most cars come from the factory slightly under damped. It is more comfortable for most people. Very under damped, however, can cause nausea, and isn't comfortable for most people. Fine line to walk.

Well... Sum bitch. I called customer service and they had eibach spring replacements. The dumb bitch said they were 8, 10 or 12, and she was talking about kg/mm, after i told her i had 8k, and 10k on rear. Sooo can i buy new softer springs and be alright? If not i found a good deal on some spoon coilovers. Either way wont be for a month or two, just bought a audio console, and hmotors is holding a gathers rear interior for me. Ill just have to postpone carpet, seats and headlights for coilovers.

you need to man up and deal with a stiff ride. any one piece coilover is going to ride stiff. thats why you spend the money for them... function and forms are actually on the softer side of things also. you cannot adjust dampening on the type 1's either. they are only height adjustable. i would suggest selling your setup and buying a buick is its too bumpy for you.

It wouldnt bother me if we had drivable roads. Im not talking about city roads that are getting bad, its roads that havent been repaved in 10-20 years atleast. When I get a day off ill take a video of the road, and riding in my car. Im not complaining its to stiff for me, that doesnt bother me, its that its so stiff that my car gets pulled around and pulled into the other lane at 70 mph with other traffic.

Sounds more like an alignment problem than issues with the spring rates.

Yeah I have **** roads here on type 2's and I have no problems. No matter what spring rate you get no matter how much money you spend no one piece coil over can handle big bumps or potholes. That's my experience at least

x2

hopefully you had a 4-wheel alignment done after these were installed. if not, adjust the height to where you want them, sack up, and go get an alignment.

spring rates won't cause a car to "jerk around" on the road. wheels that aren't going the same directions will...
