Default Mild street setup

hi, im searching and i can mostly find aggressive setups. my car is a 06 sti and its my daily driver and i dont want anything too crazy. im not gonna autox it, just something that can handle alot better then what is currently stock. im considering the cobb swaybar package, kartboy endlinks, and prodrive springs. i just got new falken rt615's which should be nice.

do i really need to get group n strut mounts? and with the prodrives, is a alignment necessary? will tire wear be high? i can do the alignment myself if necessary.

no raggin on me please, i would like honest answers.

If you want a *really* nice street setup build it around a set of Ohlins fixed perch dampers.

Don't sweat it. There's a few daily drivers lurking in the wings here. For a mild setup, I like your choices. The WL big bars are probably too much for your plans and the softer Cobbs will give a little more compliance in a veriety of uneven bumpy or damp roads. I have the WL 29mm and its a bit much for a DD. No harshness mind you, it just needs smoother, dryer roads than I usually see.

For springs, I like your choice as well. In another thread Myles (of RCE fame) hinted that a "regular guy" spring is in the plans. Not sure how long you want to wait, it could be a little while. Myles also hinted that a new strut is in the works, which sounds like it will be out shortly. I'd highly recommend replacing the strut with the either Ohlins, or the "Myles" strut when available. Depending on your budget and strut availability, that could be part of a longer term plan.

As for group-n's, opinions may vary, but I'd consider this a "nice to have" rather than a "must have" for a mild street setup. I went the RCE camber plate route because I wanted more camber without another bolt, and trackside adjustabilty. Depending on how much camber you can get with the stock setup, the RCE plates may be desireble for the camber adjustment alone. On my 06, -0.4 was the max I could get and that aint enough.

Lastly, I'd highly recommend the ALK. In fact I'd put at the top of the list of changes. This is a "must have" IMO.

The only change that won't require and alignment are the sways. Yes, pleased get it done or do it your self, assuming you have a camber guage. Also, in case you didn't know many STIs came from the factory with positive camber up front. I had a bit on one and just about 0 on the other. If you haven't aligned the car yet, I'd do that before you make any changes. Get a proper baseline before making any changes so seperate the impact of a upgraded part from a alignment setting.

I have the Hotchkis street swaybars, which are very close if not identical to the Cobbs. I also have Prodrive springs. I daily drive the car, 180 miles or so lately.

The spring and tire changes you are making will make the car more comfortable, although I will not go as far as to say the car becomes actually comfortable; it's still a hard riding little beastie.

The spring and swaybar changes will make it handle better. If I have any qualms about the swaybars it is that I wash out much more easily during initial turnin under limited traction situations. That is offset by quicker rotation -- quicker transition from understeer through neutral to oversteer -- so I have learned to live with it.

Based on many comments I have read here from folks with a lot more experience than me, I recommend that you do. I have them.

You're taking the suspension apart, including complete removal of the camber bolts. When you put it all back together your ride height will be (a little) different. Alignment isn't a good idea, it's a necessity.

Tire wear will depend on how you align it. People around here love to dial in negative camber in front, which will improve steering response but will also wear the inside edges of the front tires faster.

haroman311, I'd recommend that you get larger sway bars and trim/replace your stock bump stops. I'd evaluate that before spending any additional money. However, if you're still not happy, replace the stock struts with something better (Ohlins or D-specs when available). Replacing your springs on stock struts is going to be counter-productive in many ways for a street setup.

I thought the 2005 and 2006 STI's already came with revised geometry to allow dive/lift and didn't see much improvement from the kit? There was a thread on Nasioc stating this, IIRC.

At least the STI (I assume the WRX is the same) has the anti-lift/dive geometry still thier in 06. Take a look at the angle of your control arm. If its higher in the back, that's the anti(%#^@) geometry. If its perpendicular to the ground, then there's no anti dive in it.

Since you're not going to be autocrossing it, it sounds like you want to just lower it a bit and give it a more aggressive stance.

I'd say get some JDM pink springs or Prodrives and a larger rear swaybar. An alignment is always recommended whenever you have to remove the struts.

I'm running the Cobb sways on the middle rear setting with adj sway mounts, Kartboy links, and Tanabe 210 springs. Major improvement in handling and no issues for daily driving so far.

My daily setup is RCE Springs, WL 27F/24R sways, steering rack bushings, strut bars front and rear and rear group n top hat... I didn't get the front because i was going to go with camber plate shortly after but $$$ didn't let me do that... Camber plate and ALK are up next in the list...

It is a big rought but not too bad of a ride... You will get used to it unless you drive on really bad roads...
