Icon2 91 si supension upgrade

Sorry if this topic has already been covered but I looked for a thread and couldn't find one. I'm currently in the market to buy some new coilovers for my crx. I've done lots of research on the topic and as always it comes down to how much you're willing to spend. I guess the money part isn't the biggest issue, I can afford the tein super sports and was what I was originally going to go with. Kept doing my research and came across a few other threads else where and people were talking about progress coilovers. I haven't heard of them up until now but people kept saying they're the best bang for you're buck. I should probably say that my goals with the car is to go pretty low but now scraping low. I'm more than likely never going to track the car and maybe take it to the strip once or twice. Just want a DD that sits pretty low but is somewhat decent ride. Was wondering if anyone had some first hand experience with this brand considering it would save me a nice chunk of money to put towards my wheels and tires. Thanks again in advance.

I picked a set up a while back. Haven't driven on them, but I have them installed, and they're a great quality setup.

I'm sure it'll be a touch lower once everything is back in the car.

I think you best bet is Koni/GC. Never heard a negative word about this setup. It can be had for around $700

Just an FYI: The lower you go, the higher the spring rate you will need to keep from scrapping. The higher the spring rate, the stiffer the ride. Low ride height and low spring rate = scrapping/rubbing on any bump and possibly even during corners.

Koni/Ground control combo will be the most popular, for good reason too.

This is what all the hipster trendy stance fanboyz don't understand.

The lower the car, the poorer quality of ride and more attention needing to be paid wherever you drive.

Yeah I totally understand that the lower you go the ride quality is compromised, but I know some set-ups wont be as harsh. I've riden in plenty of slammed rides, one of my buddies drift 240 is slammed and rides real hard but also has **** coilovers. Yeah I've seen the koni/gc setups all over. I really wanted a fully adjustable coilover but what are the pro's of going with that setup?

I dont care what shocks or coilovers you have, If you want it slammed, you are going to need high spring rates, and it is going to be STIFF. If you want to slam on Koni/GC, you will need 500lb+ if not more, and that will be a pretty stiff ride.

i have a set of BC br series on my hatch and i have to say i absolutely love them. i daily it and it's actually comfortable and perfectly driveable. i'm not slammed because of the sh*t roads around here but i still have a large amount of space where i can lower and i'm certain it won't hit the stoppers any time soon. they are pretty good for their price and include several features such as 30 way adjustment compared to a tein super sport kit which is 16 way.
also costs less if i'm not mistaken.
i got mine (br-rs fork type) for about 1050$

Exactly, lol. Like I said, the lower you go, the stiffer your springs need to be. Stiffer springs = Stiffer ride, but does not always equal harsh.

Koni's are infintely adjustable...

Don't get hung up on what ever companies spit out for some number of adjustability.

If you want to go low and still handle decent (I say decent because you won't get great without every other bush, arm, best tires, seam welded chassis etc) get adjustable suspension that is dummy bottom, which is where you can adjust the height by spinning the bottom mount up the shaft as well as the spring collars.

Most entry level tein and koni are only spring rate adjustable so you can't go slammed without spring coming uncaptive

Dummy bottom? Spring rate adjustable? Spring uncaptive? Wtf? Lol

You cannot adjust the spring rate.. And I can only assume you mean using a setup like Koni and Ground Control is not a pre-loaded coilover. Which doesn't really matter. I'm assuming by "uncaptive" you mean the spring dropping from the top mount when the suspension is at full droop(going back to pre-loaded coilover) which again is not a problem.

About how low do you have those set at, or how much thread could you still use? My car already has some shitty ebay coilovers on it from when I bought it but it seems lower than that. Was wanting to go a little bit lower than that still

Dummy bottom = bottom mount is adjustable, like you see on D2 and BC suspension

Spring rate adjustable = height is only adjustable by moving the locking collars(spring seat) meaning if you go too far the spring becomes uncaptive, hence why bottom adjusting(dummy bottom) is the best solution for going low and still having travel.


Sorry New Zealand lingo lol

So how does that ride with it adjusted maxed out? Also, a bit off topic but my brother has an eg sedan and was also looking to uograde suspension. I came across a hardly used get on tein Ss' for his car for $600 but hes dead set on koni yellows/ Ground Control. What would be the pros and cons to both of those setups?

Super Streets are ok for daily use. I can't comment on Civics but in my R34 they didn't go low and were a bit to soft for corners ( with stock sway bars)

This is my M35 with D2s in it, still has 50mm off adjustment on the bottom but the spring is fully seated and captive

So "upgrade"???
What is your GOAL? Slammed, AutoX, drag, road race, etc.

To add to all the mess above, simply pairing whatever shock with a high rate spring is a bad idea.
If you figure out that your goal will require a heavy rate spring, then you need to ensure your shock is valved for that spring.
Adjustable does NOT mean it can magically handle the spring.
If you were to put to much spring on a stock shock then it will result in a bouncy ride -
Activate sequence "Go Riceboi, Go RiceBOI - GO!"
Not even safe for street driving, or driving at all for that matter.

I know the goals for my car as stated above is to be just a daily driver that's going relatively low but not dragging my oil pan around or anything. I understand you don't just mismatch any spring to any shock, I understand how it all works. I was just looking for some insight if people had used them and had some feedback

Koni Yellows and Ground Controls are without a doubt the best bang for your buck. Great track suspension, as well as great name brands if you ever wanted to show the car.

Yeah that seems to be the consensus that I keep hearing. Would it still be the best option when I could get the tein ss's for $600 though? I know the Koni/GC's would be a little more but what Im hearing from this thread is that the SS's are more of a track setup?

Get the Koni/GC. And no, the SS are not a 'track setup'. They are not anywhere near as good as koni/gc. They will be outperformed in all categories by the koni/gc, except for price. But you can find a koni/gc package for ~$800, so it's not much more. Im rocking Koni/GC with 350lb front and rear on my hatch, and couldnt be happier! The ride is just a little firmer than stock, but not at all uncomfortable.

Well guess I'll be ordering a set here asap. Guess with the suspension figured out next is the wheel set. I want my car to be low obviously but I like the look of these other flush cars. I dont want to tuck or anything but was wondering if my 91 crx si could handle 15x8 with 12 offset on stock camber with havingto pull my fenders? I know im going to have to roll the lips and tabs but would any other mods have to be done?
