Default Judge my coilovers

I purchased my STi from another user here and it already had coilovers installed.

They are the JiC FLT-TAR coilovers with 10k/8k springs on front/rear respectively. It dropped the car quite a bit and really stiffened up the suspension. Handling is awesome. Link: http://www.jic-magic.com/ViewProduct1.aspx?ProductID=33

I really know next to nothing about coilovers and suspension upgrades, I'm just curious how good these are in comparison to other top brands. All I know is these are $2500 coilovers if bought new...but that doesn't help me much.

Anyone know how they compare?

Here is a shot below for reference...

Those springs seem near double what i think they should be for a daily driver?

Ya, they are pretty stiff indeed. Even when the damper is set to its softest setting...

I'm sorry this thread is so beneath you. I'm glad I could make you feel better today!

The purpose of this thread wasn't to stroke anyone's ego, I know nothing about suspension stuff. I'm just curious if these are good, or if there are better ones out there, and how these perform against them.

Here's the deal man, no one is going to be able to really answer your question because no one knows what you want your car to be able to do and how much comfort you're willing to sacrifice for performance.

I could buy myself the most expensive, race-ready coilover set up in the world but it would be a complete waste of money to me because I have no intention of ever taking my car to the track. Would it handle like a go cart? Yes. Would I be able to live with an extremely stiff ride in my daily travels? No.

For instance, my car is strictly a DD. I wanted a suspension that enhanced performance, had a very mild drop, and erred on the side of comfort rather than straight up performance. Also, adjustable dampers were not necessary to me personally. With those objectives in mind I ended up with the GTWorx set up and RCE Blacks.

I think we can both agree that I don't know you. I also don't know what your needs and expectations are for your car. Congrats on the new car BTW. Anyway, if you aren't going to be regularly tracking the car, this set up is way overkill. If your top priority is a really low car, again this set up is way overkill. If you want high performance and are willing to sacrifice lots of comfort, then you're going to be just fine with these. If you also intend to spend a significant amount of time at the track, then you've got a good quality set up for it.

Are these "good" really stiff race-ready coils? Yes they are.

Are there better really stiff race-ready coils out there? Probably. No matter what, there's always going to be something better but at what cost?

What it comes down to at the end of the day is, can you deal with the harsh ride for the long run? As Tieva-Boy said previously, these are not daily driver coils because the spring rates are too high and I agree. If you like 'em though, then run 'em. After all, they came with the car so if you're cool with them then you've got well built coils that many people like. If you think you could use a little more comfort after a while, find something with a lower spring rate. It doesn't matter how they compare to other brands because these, just like any other coilovers, are purpose built for comfort or quality, or performance, or price, or looks, or any combination of features that will fill a customer's needs.

Awesome, thanks for that response. I guess for my needs I'm looking for better performance than stock. I have the stock coilovers w/RCE blacks and they're alright. Definitely more comfortable than the ones above. I don't even plan on tracking it. Maybe a 1/4 mile run here and there, but not much.

Would I prefer more comfortable coilovers than the FiC? Sure. I was just asking more out of curiosity if FiC is a good brand and if these are a nice kit. I like the handling but they can be a bit too stiff for daily driving sometimes. I don't plan on spending much on any suspension mods (already have full whiteline sways kit too).

I emailed FiC to see if they have a "trade" program...go to 8k/6k vs the 10k/8k that are on there now. Thanks again.

Any suggestion on something in between? There are so many, and lots of posts don't have any real data to suggest one brand over the other, which leaves me looking purely at price.

I'm making an assumption here that when you say "stock coilovers" that you mean the OEM dampers (fixed height/non-adjustable) that came on the car from factory? From that I'm assuming that you're satisfied with the subtle drop that the RCE blacks give, just more concerned about performance than slamming your car.

With those assumptions in mind, you could def. try the route you're going by emailing JiC to see if you can get springs with lower rates. If that works then it might very well meet your needs. I can't speak too much to coilovers because I just think they're a pain in the ass so I always go with dampers that aren't height adjustable so I can set it and forget it.

If you're cool with the RCE Blacks, you could probably unload those JiC coilovers easily and get a set of the Bilstein GTWorx dampers or the Koni inserts to go with the Blacks. Both will get you better performance than stock. You can adjust the damping with the Konis, you can not with the Bilsteins. The Blacks work well with both. I have the Bilsteins and can vouch for their performance. Many people have had great success with the Koni inserts as well. Those two damper options are probably the best two for what you're looking for regarding a middle ground between comfort and performance.

Yes, stock coilovers = stock dampers w/stock springs

The RCE blacks aren't quite as low as I'd like them to be, compared to the low-low FiC. The pick posted above has the car a bit lower than I want. The RCE's were about 1.5" higher at minimum.

Make sure you take into consideration that setting the car up too low will start to negatively impact actual performance. The car has a sweet spot and it's lower limits aren't much lower than what RCE yellows, EPICs, or simliar springs. Since you seem like you're not interested in tucking your wheels or going low-low, you could probably go a little higher than the picture with the JiC's and still be ok. It's just figuring out if you can get softer springs.

there is no way in a cold frozen over hell that i would ever even think about using JIC coil overs on the street

ever

and too low is just that.....like was posted above....going too low---more than an inch or so below stock is IT really.....will make the car handle worse for a whole bunch of reasons
so dont


and just because it rides hard does NOT mean it is gonna handle well....THAT is kiddie stupidity right there

OK so I emailed JiC. They said they could arrange a fair trade, I'll send them the 10k springs and they send me 6k. So then I can run 8k front, 6k rear.

How much will this impact my ride stiffness? It's a pretty fair trade, but waste of time for me if its not going to be much softer in the end. Thanks for any help.

Here is their chart for spring rates:

kg lbs/inch
4 225
5 281
6 337
7 393
8 450
9 506
10 564

I think it would still be too stiff for me. My blacks are as stiff as I want to go with mine as a street car. If you already have the blacks, I would just stick with them. It is a good height for both looks and performance.

I believe the blacks are 275 lbs/in in the front, not sure what the rears are, if that helps to compare the rates comfort wise.

For comparison's sake, I believe RCE Yellows are 330/330 lbs and Blacks are 275/250lbs. 450/337lbs. (8k/6k) is still going to be really stiff in my opinion. I personally don't even think I could handle Yellows on a DD.

I don't think that set up is going to be much softer for you to be honest.

Taken from FastWRX site that sells both the yellows and blacks:

RCE Yellow Springs 08+ WRX/STi -- Lowers the car approximately 15mm. Spring rates are an aggressive 330 lbs/in front and 335 lbs/in rear.

RCE Regular Guy Black Springs 2008+ WRX STI -- Lowers 5mm. 320 lb/in front, 320 lb/in rear.


I'm currently running the stock struts with the RCE blacks on the car, but I remembered a noticeable change in cornering ability when I removed the JiC coils. I'm just comparing it to some canyon driving, and the RCEs don't seem to corner as nicely.

Thanks for the input!

It's not the RCE's that are the problem, it's the under-damped OEM struts that's killing you in the corners. They're just flat out awful.

Agreed. Get them revalved by Feal. My friend has great results from them. Ride is firm, but surprizingly comfortable. It is amazing in bumpy corners. I have not done this yet either and the difference between his and mine is night and day. If xmas wasnt right around the corner, i would send mine out right now.

8k and 6k is still going to be very firm. Unless you are going to compete or do track days I would recommend doing the trade and then selling the coilovers to some one who will use them for competition. With the traded spring rates it will be easier to sell them.

Coilovers on a daily driver are such a pain to live with. It's ok if you like to futz with your stuff all the time. Conventional springs/struts are so much easier to live with. Proper coilover use requires maintenance that standard spring/struts don't, although with the OP living in AZ is a plus (no salt). Again if you like to mess with your stuff all the time this is not so much an issue.

You can then get some Bilstein dampers with the RCE springs and you will be so much better off and happier for a daily driver.

Good luck
