Quick question for u guys. Im just getting into road racing and would like some sound advice on my suspension.

As of now i have coils 6/8 spring rate camber plates.

Wheels 18x9 33+ offset (yes i know its what i could get in a moments notice due to 2 wheels cracked after someone hit the curb) due plan on fender flares soon
Tires 235/40 g-force comp 2.
Street and track set up till i can get a track set of wheels also.

Hub to fender 14f 13.75r
Camber -3f -2r

Anything i should think of doing or adjusting for when im able too????

bboy: are you targeting STU? Flares won't be legal. And you'll probably want to run a 245 Star Spec or similar, and likely less camber in the rear...

Thanks. So no flares in stu ok. 1.5-1.8 in rear sounds more on mark u think? 235 will have to do for now. I dont think i can fit a 245 unless i do a 245/35. Is a 35 enough sidewall???

It's up to you... do you want better rotation? I'd personally go less than 1.5* camber.

35 should be enough if you're running 18s... it would be almost the exact circumference of a 245/40/17.

The 245/35 will be on the wheels next. Im sure after a few events the current will be wore out enough.

Eventually i will get a track set of wheels whats a good offset that will fit a 18x9.5 or 18x10 without hitting anything?

Im sorry for the questions. Im finally getting to a financial position to get all my track license and get my car to a full track car.

I have done a few track day races for everyone and have done very well. I feel its time for me to step it up.

I currently have a built block with head work and cams headers tbe ewg still vf39 turbo till able to get my new set up which shouldn't be much longer.

Eventually will get new coils with custom valving and springs.

You realize this is an autocross thread and not a road racing thread, right? Oh, and head work, cams, external waste gate, different turbo etc. are all not STU legal.

Quick question.

Stepping up to STU from stock and am wondering if you need a front sway bar? It's already 21mm so I figure if I buy a 22mm rear that is adjustable I should be good, no? Maybe going to SP eventually.

Doing track days as well if that helps.

I just don't want to buy something I don't need.

edit: wrx, not sti. Also likely getting koni adjustables and RCE yellows if that helps as well. Car is DD and I don't want to go too crazy on spring rates.

Yeah I was starting to think with these questions he might be asking about Super Touring club racing class which is also called STU.

I'm assuming the front stock sway is 21mm? I just moved from an 09 WRX to a 2013 STi, so I'm taking both bars (24f/22r) from the WRX and moving it over to the new car. I'm not sure if only the rear bar on your car is going to make you as competitive as you might like. Also, are you planning on getting a performance alignment?

Looking for rules clarification -

I have a 2005 STi with the stock wing removed, and replaced by the 2007-2008 (? not sure the years it was an option) Limited lip spoiler. I'm assuming that 14.2.F.1 doesn't apply due to the lip spoiler being from a later year (though the rule doesn't specify model year). Would this fall under comfort & convenience, or am I going to have to bolt on a different trunk with a stock spoiler for running in STU at events? (I plan on running 2-3 national events in addition to my regional efforts this year)

You can definitely remove the stock spoiler. I'm not sure if you can legally add the Limited spoiler though.

What i'm trying to do is make it more neutral handling and people say where I am that a 24f or 22f and 22r with the front on the lowest setting and the hear or medium or stiff works great for that. The thing is the 24 and 22 sway bars usually on their lowest setting is like a 21mm bar so I was wondering if you still really need to buy one because of that.

I am getting a performance alignment before i move over. Getting new wheels as well.

I'm not looking to win more looking to have fun but if it would make it not really competative at all to not get a front bar then I would just buy one. Trying to save pennies here, lol.

I'll probably just end up getting it....

Anyone have rce yellows in STU? Just wondering how you feel about them. I could get ground control springs with higher rates.

Hey Guys,

I figured this is a better thread to ask a simple question rather than waste space with a separate thread.

Anyways, I'm going to be new to turbo tuning. I currently drive a BMW Z4M so I am completely new to that boost. Not new to autocross, new to turbos and autocross.

Upcoming on buying a 2013 STI 5-Door


I hear a lot about OTS (off the shelf?) and Protune (I'm assuming via custom in-person tune?). I also hear about AP (AccessPort?) tunes, although via my research I though these adjust boost levels?

Essentially w/a trimmed STU car Exhaust, DP...etc, you need to adjust Fuel/Air Ratio to avoid pre-dent?

I guess what I want to know is, what the best route to go with this "tuning". Find a well-known shop for a STU tune? Via the discussions here, your talk seems that this tune is pretty cookie-cutter, although researching it doesn't seem this way.

Turn-in Concepts is a couple hours away, off the top of my head that's the only shop that specializes in subarus .



I'm just very concerned about pre-dent and of course that dreaded ringland failure, even though it seems more hype than actual truth.

And they will have there BRAND NEW Dyno up and running before the start of autocross season. And their pricing is going to be EXTREMELY fair.

This ^ Call Greg at TiC if you are wanting to look into getting a Dyno tune, the drive down to TiC is well worth it and they are great guys to work with. Otherwise, get ahold of me and we can talk about opensource options (pricing and who to get ahold of).

And to summarize an STU tune: don't touch boost in any way, shape or form. Any naturally occurring boost increases from legal modifications (although bound to be small) can be tuned for. Otherwise, clean things up and then go fast.

Went through 2 engines autocrossing my 08 STI, so I don't think it's hype at all.

Sooo, I'm scrolling through the STU rulebook looking for ways to go moar faster. I want to put a turbo inlet on, but the rules seem a little unclear. Anyone clarify this for me before I go spend 250 bucks on a part I can't use?

"The air intake system up to, but not including, the engine inlet may be modified or replaced. The engine inlet is the throttle body, carburetor, compressor inlet, or intake manifold, whichever comes first."

Am I correct in assuming the "turbo inlet" is in this case the "compressor inlet" as described by the above rules? I know this may seem like a dumb question, but I want to be sure about it.

Didn't most failures occur with 08s rather than later models?


Yazel, thanks for the information. I did a karting endurance event in Cinci this past fall and they were sponsoring the event. Really cool people.

Ill talk to them when I get closer to go time. How has your car been? Any issues with lean mixtures or anything of that source?

The ringland failures started occurring with 07+ models. I know the 2012's were still blowing left and right quite a bit, not sure about 2013 yet. Keep in mind typical STU tunes run a lot of timing, which only makes things even more aggressive. Combine that with some bad gas/detonation/blow-by and you have a recipe for a cracked ringland. It's not a question of if, but when.

I know of two local 2012 model year STi's that have had the ringland problems.

Also, I was at that Enduro at Full Throttle on TiC's team Did you grab one of the 10% off coupons? If not I will try to get you one.

As for my tune, it has been great. I have never had any issue with a lean mixture and my tuner is a great guy. I am running slightly rich at the very top end now thanks to a new OEM fuel filter (old one was kind of nasty), but I will get that taken care of when I get around to installing an EL header and up-pipe.

Ahh, okay. Funny...

I got a 10% coupon, but realistically anything won't happen til late next year, I'm just trying to do research and be an educated buyer.

Looking to order June/July...but now I may try to hold out for a 2014 w/a new engine to avoid these issues. It may be a gamble, but hell...it's a gamble on blowing a ringland now.


Sorry for minor derail
