I'm not in a position to check my hub to fender measurements right now but does everyone agree with the ~13.5" measurement with Bilsteins/Blacks? I sent RCE an email earlier, hopefully they can clear things up. There are a few guys on here running this setup (Ying and mkvaron) with 2011 models and they don't look to have dropped more than an 1".

The rear hub to fender measurement can depend on where you put the rear circlip. Mine's placed in the middle setting.

Right now my h/f measurement's 14.6F/14.5R with the RCE blacks for STI's and the bilstein struts.

I'm more concerned with the front since it doesn't have any adjustment.

This is a 13.5" hub to fender measurement: really not that low if you think about it. Though it does make the difference between hitting the cement parking stops in parking lots and having the bottom of your bumper slide over it.
its something that should be said. not everyone will use the bilsteins. and making the blanket statement that the lowering is lower for ALL 11+ is incorrect.

the amount the springs lower is 19mm. regardless of what you put them on.

if you are getting additional lowering from other means (different shocks or camber plate) then you need to address that separately. and RCE has OK'd the blacks for 2011+ stock struts, though i agree you will get better performance from a upgraded shock like bilstein or koni.

Do you even want to go lower? If not then just use the STI's RCE blacks

I think since the topic is about the GTworx kit which includes the Bilsteins, it's safe to assume specs given based on experiences are for the springs + struts combo, unless otherwise stated. As for the blacks on stock struts....I'd be okay with it if RCE was willing to warranty any blown struts caused by running blacks on them. Until then, having stiffer springs on an already underdamped system that lowers the car sounds like a bad idea to me.

I should state I'm just a n00b giving you gents my experiences/regurgitating crap I've read here. Pinch of salt and all that jazz.

I wouldn't mind a mild drop, like the springs by themselves. But I'm a little worried now about the combo of Bils/RCE Blacks being too low for me.

BTW, thanks for the extremely quick responses guys, I appreciate it!

In which case, consider the RCE yellows instead of the blacks. The bils are valved for 330/330 springs, so it's a better match.

Why are you worried about "being too low"? Got steep driveways/parking lot entrances around your neck of the woods?

I would have gone with the yellows to begin with but I'm worried they'd be too stiff for my taste and were I live.

I'm running 320/320 springs, and I personally think they feel better than the softer rated ones on my bilsteins. Do some research on what an overdamped suspension setup is, that'll give you an idea on why it'd be better to have springs that match the shocks. Unless someone here's kind enough to provide a little cliffnote.

So you're running the STI blacks? Is the only reason you went that route to keep stock ride height?

The overdamped system felt too "crashy" when going over dips in the roads and rebounds after bumps, so I wanted to improve that feel a little and get some of my ride height back as well. That's why I went with the STI blacks instead of the WRX yellows on my second go around. Another option for you would be to use your stock springs and get the bilsteins revalved for your stock spring rates. That would be the most comfortable option which provides a little drop (since you'll still be using the bilsteins).

Ah, gotcha. In response to your question above, I do have a few steep driveways in my area for work, friends places. Plus, occasionally we get a decent amount of snow and I worry about getting too much caked in the wheel wells. Any issues when you had the WRX blacks before with ground clearance?

I might look into the STI springs, I wasn't sure if they'd be compatible and didn't know if the ~10lb difference would be noticeable. Your fender to hub clearance is equal to stock?

I'm not 100% sure about equal to stock, but I'm at 14.6F/14.5R with the STI blacks. Stock should be 14.25-14.5 IRRC.

I did have a decent amount of snow/mud caked between the tires/wheel well/mudflaps during the last snow storm. Pretty sure I was the neighborhood snowplow during that little escapade as well. Seems to be better now that I'm riding a bit higher during the snow we got 2 days ago. I'll snap a photo of my current ride height when there's a bit more sunlight here lol.

I called RCE about my stupid idea of running STi Blacks on the bilsteins and they weren't very helpful regarding what would happen. At least they were polite and responded quickly!

That's the issue, I'm okay with what I have now but don't really want to go any higher. I also don't want to be the snowplow either haha.

Maybe I should suck it up and try the yellows. The only problem there is that I already bought blacks

Maybe post in your regional forum and see if you can get someone with these setups to give you a ride, that way you can get a feel for them yourself. A gent on my regional forum was kind enough to drive me around back when I was interested in H&R coilovers. Great guy, sweet car, hated how rough everything was.

There is a guy with a 2012 STI at my job. He parks in the lot. I stuck my fingers into the wheel wells to see if there is a difference in ride height, stock STI vs WRX 11-13'. The stock STI is about 1 finger lower in the rear and half a finger lower in the front than a stock WRX. According to Subaru's website the STI has a height of 57.9 inches and the WRX has a height of 58.1 inches, which is a 5mm difference.

So you have to consider, even though the black STI springs drop 5mm, the STI is lower to begin with. IF that 5mm is even accurate, because the postings on their site change frequently and aren't always up to date. I.E. they used to advertise a 10mm drop for the WRX, later which they updated to 15mm.

The guys at RCE have done the calculations, and they know what they are doing. Stick with WRX springs for the WRX, and STI springs for the STI.

If you want to maintain maximum ride height on your WRX, you have to go with the WRX yellow springs. I spoke with Myles at RCE and he was very sure the Black springs drop the WRX lower. Look at it this way, putting the WRX yellow springs on will give your WRX a ride height very close to a stock STI. Which is very cool IMO.

GregOrz,

What are you running, blacks or yellows? I thought I had read in another thread that you went with blacks. How is the ride height for you in NYC?

Thanks!

Thanks!

I changed it to Yellows last minute when I was on the phone with Myles, because:

1) The Bilsteins are originally valved for the Yellows
2) It maintains a higher ride height than the blacks
3) The stiffer rate will keep you off your bump stops

I posted pictures in the other thread of my springs and Bilsteins. I'm getting them installed soon, I am just waiting on OEM assembly parts to keep my stock shock and struts intact so I can swap them out easily whenever I want.

Stay tuned I will post pictures, info and review within a month or so.

I posted in my local forum based on garudatwo suggestion hoping someone would have yellows so I could see if they are really too stiff for me.

Correct me if I'm wrong, but wont you need to get an alignment each time if you're swapping between OEM and your Bil/Yellows setup?

i have never gotten an alignment in 52k miles. thats with stocks and sti pinks, and now bils and yellows. would it help, im sure. i scribed the struts so they could be put back in the same location and tightened. my tires have never worn funny either. i have rce camber plates wating for warm weather. i am gonna get an alignment when i install those.

Keep in mind that the STi is also roughly 170 pounds more than the WRX. Your finger-in-wheelwell test isn't exactly accurate, since the STI is also running 18" wheels. It's a FACT that STi Blacks will results in a hub-to-fender measurements of ~14.5" on a WRX with Bilsteins. That's not something RCE will tell you though, since they never tried it.

What about the Subaru advertised ride height of 57.9 inches for the WRX vs 58.1 for the STI? The STI may have 18 inch rims, but the rubber is also thinner....
