Scroll down for modifications and pics ...

Many thanks to those who nominated my 2004 WRX. I never thought it that special, but a few of you seem to. I love the fact the side skirts were never painted. :p

I was mostly a WRX n00b when I bought it new on 3/30/2004. I had read an article about the then new WRX and the SPT go fast bits available for it on some time before I bought the WRX. Thinking this was the path to the ultimate WRX handling package I had the dealer install the SPT suspension bits mentioned as part of the financed purchase price within a week of taking delivery.

Added at that time were 17" x 7" OZ Superleggeras with 225/45 Goodyear Eagle F1 GS-D3. Thought I had perfect handling all wrapped up. It turns out I was not even close. Don't believe everything you read in automotive magazines.

In 2004 Subaru gave you a free one year membership to the SCCA when you bought a WRX. About a year later I finally joined up. After starting to autocross the WRX the shortcomings of the setup started to become obvious.

5 years later and after a total of 7 sway bars, 4 sets of springs, 4 sets of struts, 2 sets of front camber plates and 4 different brands / models of tires I finally have the WRX right where I want it for a perfect balance between daily driver and autocross toy.

The engine mod path has been a relatively slow but steady one starting with Cobb stage 1 back in July 2004. Over the years I think I have found the perfect tune and components for daily driver and autocross toy. The engine mods have bumped me into SM, so I will not be competitive in autocross in that class. Just as well as I am not a very competitive or overly talented driver.

As the WRX is now 18+ years old, it has been retired from autocross as I want to keep it running a least a few more relatively trouble free more years.

Once again a thousand thanks for the recognition. :)

This image below depicts the WRX before I had my current suspension setup. There was a lot more body roll then. The struts and springs were v7 STi, and a wimpy 19mm front sway bar. The newer autocross images with the WRX in SM class and track day pics (#13, no letters) show the current setup. BIG difference.

Whats the offset on those wheels? sorry if its in your mods list i couldn't find it.
Ah, forgot to add that. It is +42 which is on the very outside edge of being too far out. I need the negative camber to keep from rubbing on the unrolled fenders.

She is pretty!

Seeing how you found the perfect daily and autocross suspension I will be doing this exact mod list. Thanks bro and awesome car
I have read the Öhlins struts are no longer available in the US. :(

Very nice blobeye Bill... Your car is my favorite blob I've seen so far, its so clean, subtle, and great DD setup...

I never even bothered to nominate my car for COTM because I knew it stood no chance.

Considering you included the umlaut, it appears you're not just meticulous about your detailing either...

There aren't many strut options for us STI owners anymore :sadwave:

Oh, the dots above the "O" - did not know the name for them.

Well that's how it is spelled.

Lolz. Believe it or not, I haven't had to touch up that many the 4ish years I've had mine painted... Mudflaps definitely help with that!
Autox much? Pylons eat side skirt paint. Just ask JR (wrx wagone).

Post detail pics below. Pretty damn good for an over 7 year old car.
