So.... STI front spring rates 5.8K = 324 STI rear spring rates 5.3k = 296 this would mean that the rates for the yellows are close to OEM, and yet offer the 3/4 in drop, correct? |

Are the new sway bars backwards compatible to previous gen?

Just finished auto-crossing the first time Sunday in my 2015 WRX. Car definitely plows when taking speed into turns. A lot of the under-steer is my fault but I cant help to contemplate a larger rear swaybar. I am sure negative camber in the front and rear will help but not eliminate like someone said above. I am wondering what I should do:
Note: This is also my my DD so I'd like to not have to max the negative camber as I will have it from April-ish - Early November :/ Don't know exactly how this will affect my DDing. I think the shocks are a perfect mix for DDing & Autocross at the moment and may move to something adjustable at around 60k miles or so when these wear out a little... 3 options: 1) No Camber & Get a Rear Sway? Which Size and what adjustment? I am thinking a 22 Perrin or 22 Whiteline 3 hole adjustable since the front is 23 and probably the middle or stiffest setting... I want the car to be close to neutral on auto-x without feeling out of control when taking turns at higher speeds (on/off ramps and such or track if I ever do that) 2) Max Negative Camber no Sway - I'd rather do this as I know that a sway isn't hard to put on but this is just a cheaper easier fix. At least to me and I don't have to install anything and mess with settings. 3) Max Negative Camber & Sway - Doing Both and probably a 22 bar on its softest setting? |

If the car is DD with occasional autox and you want to stay on stock suspension/springs then you are right your choices are a combination of camber and bars. Most people that autox want more oversteer so they run a stiffer rear bar, more front camber and less rear camber but this needs to be compromised for street use and your driving style/preference. General suggestions- Front camber: max out but match side to side front camber (probably around -1.5 deg) or add camber bolts and get as close to -2 deg as you can. Rear camber: -1.0 to -1.2 deg is a good street/autox compromise Swaybars: The front bar is probably fine but the ability to stiffen the rear bar will give the ability to change from DD to autox very easily. With stock suspension I'd be looking at a 22mm solid rear bar (21, 22, 23mm settings) with 22 or 23mm for autox and 21mm for DD. Suggestion: better tires DII or RE11A. |

Keep in mind that different modifications will put you in a different class. This may not matter to you, but if it does, try to read up on the rulebook (http://www.scca.com/solo/content.cfm?cid=44517), or look at this thread. http://forums.nasioc.com/forums/showthread.php?t=970625
Like I said, might not matter for you, and you could just be racing on raw times to see where stack up to others. And that's totally cool. Mike K |

Definitely need some front camber no matter what option. Start there...it's cheap and easy and a "must do."

I think I will start with -1.5 camber in the front and -1.0 in the rear in the spring with new tires, along with tire pressures about 4 psi higher in the front and see how that goes, I may get the 22mm bar if it's still too much understeer... Quote:

So will these springs for the WRX lower the car a bit more than the STI springs or is it just because the STI is a little lower to start? Will the ground clearance effectively be the same? Also are these springs the same rate for the WRX and STI?

Will the differences between yellow and black for 15 WRX be significant like last gen?

This is my car in the pictures. They've only been on two days. No, the drop isn't crazy low, the ride is not harsh, and it doesn't make for a bumpy/bouncy ride. What is does do is ride much more smoothly, corning as been nicely flattened out, and Im quite happy with the drop.
I highly recommend these springs!!! |
