Legal as long you keep the AP to a STU-legal map with no boost changes.

That's awesome. I'm not "waiting," and I don't think I'll ever be "done" with any car I race, until it's upside down in a ditch somewhere on a rally stage.

Oh and to answer your second question of competitiveness...well, not knowing you as the driver, but nationally, coilovers at a minimum along with many other mods (lightweight seats, headers, lightweight battery, etc). Locally, you should be fine and have fun. Afterall, isn't what the sport is about is to have fun?

That is why I have set a limit for myself in my mods and my goals for it. Besides I don't have a ton of money to throw at the car. I work a second job for mod money which I only plan on having for another 6 months.

I don't plan on going to nationals...sorry if I wasn't clear. Yes you are correct it is all about the fun.

Thanks for the input folks.

Any must have suggestions?

To have fun and do well locally, all you really need is a pair of camber bolts to get more camber out of the front, and maybe a big front bar to maintain it. All that other stuff is just a waste of money.

Mine was totally stock except for steering rack bushings, shifter bushings and brake pads at the last autox course setup day, and I had a HUUUUGE amount of fun with it. I didn't even have camber bolts added to the front, because I wasn't planning on doing much steering with the front tires. I've since added Konis (mostly for ride quality), and hope to have just as much fun at the autox this weekend.

You really don't need to "set up" an STi much to have fun and do very well at local autoxes. A good coilover suspension makes a big difference in control, but makes very little difference in times.

PDXtuning.com has a STU legal 93 octane map available with their maps.

The Accessport with a STU-legal Protune is the best upgrade you'll make to the engine.

Get those engine mounts on there pronto if yours are the 'plastic' variety.

Yeah, maybe in your region you can get away with that. I've got Mr. Neary to play with and if you don't come fully prepped you are gonna get killedededed.

I disagree...coilovers add quite a bit and a lot more than just feel.

All I'm saying is...

The difference between a fast driver and a slow driver is much greater than the difference between coilovers and not coilovers. The two cars just require a different driving style to go fast.

If you're just looking to have fun and be somewhat competitive (or kick ass if you actually have talent) without spending a whole lot of money - which is something the OP mentioned, btw - it doesn't take anything more than getting in the car and driving it. But a little front camber helps avoid killing the tires prematurely... which also saves money that can be spent on more events.

It all comes down to whether you want to spend an extra $10,000 so that you can improve your chances at winning a trophy for racing in a parking lot.

Yes, I prefer cheap and fun to expensive and fun.

In STU, to be reasonably competitive you need front neg camber, You can get it with camber bolts, slotting strut holes or drilling knuck to fit a factory camber bolt in both holes. The last being the best choice if you don't want to warry about knock ing your camber out all the time. A front sway bar, I have but don't recommend, the Stranos. WL better all around, Stranos = higher maintance and breakage on stock springs or R comps.

Switching to coilovers means the difference between being able to adjust the car to you or you adjusting to the car. Time to be had, but only in very good hands and if you understand set up.

After autocrossing with both set ups I like my coil overs, but wish Koni made inserts for us so I could have a better ride on the street. My car is a DD.

Konis rock.

I have to disagree about the method of camber adjustment, though - I've been using Eibach camber bolts in the front lower holes for autox, rallyx, track, street, gravel roads in the mountains, and wherever else I've gone in the past few years in my RSes and WRXes, and have never had one slip when adjusted to full effect. Partial adjustment with these bolts is highly not recommended - the one time I tried it, I had a bolt slip after just playing around in the dirt a little.

Here are the applicable sections of the Stock rules (which STU inherits):

Quote:
13.2.G. Roll bars and roll cages may be added (See Appendix C). It is strongly recommended that roll cages be constructed according to Section 18 of the GCR, though they must be bolted (not welded) into the automobile and be contained within the driver/passenger compartment. Roll bars may be welded in. A roll cage has more than four attachment points to the body or frame, or has bracing both fore and aft of the main hoop.
Quote:
From 13.2.H. A horizontal “harness bar” may be used as part of the installation hardware for allowed driver restraints. It may serve no other purpose (e.g., structural enhancement).

I did not know that.

Seeing as how I'm in SoCal I'll need to see if they can make me a map using Cali 91.

Yeah there the plastic ones. I was hoping that I would have already snapped them by now so Subaru would just replace them for free.

I also failed to mention low maintenance.

My car is a DD also which is one reason why I haven't bought coilovers. I don't like the extra up keep that they entail. I'll wait and see what comes out in the next year or so as far as struts/inserts go.

It's a just a harness bar. Almost like the Sparco unit but the floor bracing is near the center armrest and not by the doors.

Check out www.teamblewracing.org ... your local Subaru AX club. Also check out www.solo2.com.

I think GF210 springs and RCE Camber plates may make your front end to low. Also, as much as I love the RCE plates, your limited camber adjustment (and complete lack of caster adjustment) may not make them your best choice for AX.

I run STU in So Cal, so PM me if you have any questions.
