Default Has anyone run turbo OEM springs on an 08-11 2.5i NA?

Well, I'm looking for some information. What year springs will lower my 10 2.5i a little? 2011 sti springs? The car at the dealer looked too low. Maybe 08 wrx? And how is the ride if you have done this?

The WRX springs wont lower your car they will have increased spring rates (slightly stiffer) but no change in ride height. However you can easily source WRX springs that are made to lower the WRX that will fit your 2.5i for fairly cheap (under $300)

The suspension forum would be a better place for this.

WRX springs work on my 2.5i
I bought the lowest tien spring they had for the WRX.
I have a 2010 hatch. It worked very nice. Looks good, rides good and easy to install.

You will have to pair new dampers with the stiffer springs or the ride will get bouncy and poorly controlled.

Before you act:
http://en.wikipedia.org/wiki/Damping

More so you can skip down to the picture 2/3 down on the right. That's how your car chassis will move depending on how you dampen it. The stiffer spring you go while keeping the stock dampers, the closer to the pink wave you will get.

Ok, before you break something and since surprisingly nobody else has said it. You can NOT, i repeat, NOT lower your car on stock struts.

they will explode causing you to die in a fire.

Ok, so maybe you won't die in a fire, but they will still break, and quick. They are not meant to handle the higher spring rates that accompany lower springs. you'll need to get some new struts if you intend to get new springs.

Billistens are among the best out there, but they also come with a hefty price tag. KYB AGX struts offer a bit of adjustability and wont break the bank. if your strapped for cash, see if you can get some used 09-10 WRX struts. the 08 WRX struts are almost identical to the 2.5i so you will blow them if you put heavier springs on them, so stick with 09-10, they were made stock with higher spring rates so they can tolerate after market springs.

otherwise just look around for the amount of lowering you want in a spring and get what you want from there

^ to be honest, you don't necessarily HAVE to get new struts. The oem struts will last long enough as long as you don't beat the crap out of your car. I've had the H-tech springs on my stock struts, since 06', and only up until now, they've been squeaking like mad (which means I'll need to replace them).

Thank you for that bit of input and the link. I thought for sure someone had put on some of the used stuff on that seems to be floating around. The stock the car is under-dampened, but the ride sure is smooth and just sporty enough, kind of like my sister's 7 year old 325i BMW. So I don't want a huge change just a little lower.
BTW J-Chow, how is the ride, and how low, on those H-tech tiens? I would do those if it was maybe 1 inch lower, with 09-10 WRX struts. Anyway something to think about, and I think I might try the suspension part of this forum.

@ ImprezedinTexas
You don't want to do springs on our cars. They will blow in 2 minutes of driving.
The 06 struts are designed better I guess.
