I was under the impression that the 5 speed tranny was "reinforced" when the 2.5L came along. Is that not the case?

yeah, CUSCO coils are to come but it's all about the budget. I can't drop $3k on coils and tires right now (or before July). I'm going to the Evolution Driving School (hopefully) first and will be more helpful (IMHO) in the long run than wider tires or stiffer springs at first. Once I'm out of the school then I can focus on bigger/better stuff.

The 245 v710 fits (according to tire rack) on the 7.5" wheel. That's the minimum width and I'm a little weary of putting a big tire and mix hard turning and -3.5 degrees of camber (once coils are on) on the minimum width. I've heard that is not ideal. However, if it's feasible and SAFE then I can do that. I can't get new wheels this year unless I go the used route. Then, I'd prefer something like a 17x9 or maybe 18 if there was an advantage of going taller.

Shouldn't the sway bars and bushings/endlinks do the trick on the body roll thing? Isn't that why they're called "anti-sway" bars?

The only changes were a 3.7 final drive and a double-cone syncrho on first gear. The reinforcing of the 5MT for the 2.5L came from a myth because someone reasoned that since the torque increased, SoA must have done something to the 5MT. Then another person took that logic to hold it as truth. I can actually almost mentally recall the thread where it started from.

So then why are people breaking 3rd gear in '06s and NOT 1st and 2cnd? Even those running 20gs and the like.

I think KC pointed out the 2006+MY tranny because the 3.7 F.D. allows for someone to stay in 2nd gear all the time.

nope....STOCK TURBO'd no mods....cars is what we are having issues with...
(Basically, Kids that think the standard, drive it like a Honduh and all is good mentality)..
then theres the problem with the 06 aluminum Control arms...Breaking when you put Bigger Bars on (DS thread)...

Oh and KC...I realize that on the clutches

hmmmm...wonder if the "Bigger hoodscoop" is legal????

Well yes, people that don't know how to drive will break cars. But that's not my point. Throw a 20G on an 02 and what happens? Well, a lot of lag and 1st or 2cnd gear goes kablooey. What happens on an '06? 3rd. There has to be some change there.

The only bar to have a problem breaking control arms is the addco/strano bar. Sam is working to alleviate this problem, but it would also be solved once you leave DS. The main problem that causes the breakage is the bar compensating for a lack of spring. Up the spring rate, and you don't break the tabs off. You ALSO probably don't want to run quite that large of a bar with ESP rates, but that's subject to debate.

03 WRX Wagon

Default

Chiming in a little late here but i wanted to add my 2 cents.
I drive an ESP prepped wagon that seems to be competitive enough in my region, I just need to 'drive' it better. So far i am usually in top 3 withing 1 sec the most of the winner who is driving a Steeda Mustang. The car is not fully prepped for ESP and can still have alot to do, and my stock clutch is slipping kinna bad so thats an excuse to go in with a new clutch and flywheel which is legal.

Only thing that sucks for me in the wagon is that i have less track than the WRX sedan and i am about 75-90lbs heavier, plus the weight is all up top increasing my center of gravity. Still those factors are miniscule and i think WRX wagon or sedan can be really competitive in ESP.

One thing i would like is to put the whiteline 27mm front sway bar on the car , i remember seeing a thread where they confirmed it fits on the wagons using sperical endlinks, so money willing after i replace my clutch(which im not sure when that will be) that and a bigger rear sway bar as well should be in the future.

He speaks the truth folks. There's quite a few threads where people are making 300-350whp on 20g turbos and 1st and 2nd gear are standing up to repeated launches on the '06 trannies - however, if/when the trannies break, 3rd is the one that shatters to pieces. I'm not sure what Subaru did, but they did something to reinforce the first 2 gears.

Btw, I'm not sure if the '06 clutch is truly weaker - as it makes more torque, a bad driver is apt to wear it out more quickly than the one on the 2.0L. Besides, tuners such as Christian @ Cobb and David @ Buschur Racing have been able to run tuned vf39'd '06 WRXs on the stock clutch with no slippage.

No, a bigger scoop is not ESP legal (putts you in SM) yet a larger IC is.

I think he means the scoop from the 06+ models which you could get via UD/BD.

That reminds me...did the WRX scoop get bigger or did the STi scoop get smaller or both (since the WRX and STi appear have the same size scoop on the 06 models).

Correct - both happened. WRX and STI have the identical hood scoop for the '06-'07MY. Aerodynamics were redesigned with the new front-end to make the scoop more efficient.

And I'm under the impression that the scoop will not retrofit to '05 and earlier, is that right?

Correct Keith. Someone did the measurements in a thread and the opening the scoop covers is a completely different shape - the entire front end, headlight assembly and hood would need to be changed inorder to run an '06+ hood scoop.

Someone ran them last month on stock 06 WRX wheels and they looked fine actually.

Oh I almost forgot.





Granted, they aren't the absolute best autocross tires, but they were cheeeeap and will be my daily tires once it warms up outside.

They will be on Team Dynamics 17x9 et45 if they ever arrive . I've had them on order since November but they finally shipped from England, I'll have pics in a few weeks.

Agreed, the T56 is a stought gearbox.
Top speed for the LT1 is 68mph, and I think the LS1 is just a touch faster (only because it has a touch higher redline). I have the ratios somewhere, and for the '94+ cars, "2.88" is what comes to mind for first gear. It's different in the '93 transmission, which is why one of the UD/BD changes is to a '93 trans.

And Justin, you're right about me not remembering the gearbox differences between an STi and a regular WRX. Yours is the first WRX I've driven in literally years, and that was only 2 (frustrating) runs . The whole glass transmission issue is a real problem (at least in the earlier cars), and I don't necessarily think it's fair to blame all of it on the drivers. There are a couple of earlier WRXs with broken trannies that were the reason I stopped driving that model because I knew those drivers didn't dog the cars like certain other drivers did.

You can go ahead and mention Tom by name if you want to Karen, you don't have to call him "certain other drivers". It's simple really. If you do Pro Solo with a WRX 5-speed you will eventually get to experience the joy and cost of replacing a tranny. And that's running in STX with less power and street rubber, I'd budget at least one tranny a year if doing ESP.

I shouldn't pick on Tom, in his defense he did keep trying to get rebuilds instead of just buying a new transmission which had a lot to do with why he kept blowing them I think.

Wasn't there an issue with his gearbox case that kept causing some of those breaks and rebuilds.

I think that may be on the low end. At least STi drivers only need to carry around spare rear axles to events...

I remember hearing about that... Who knows though - I think Tom had several issues with the car's reliability which eventually led him to sell it.

Oh, I know the earlier ones were a real problem. Time will truely tell if the '06s are stronger or not, I suppose.

I can't wait till you start blowing tranny's and the rest of us only break axles...just kidding..I too can't complain that my only thing so far is 1 axle replaced because of racing..

Digi ... Sway bars help control lean in cornering but not under braking. One problem with WRX's is that they lift their inside rear wheel in corner entry. Stiffer springs help in that regard ... but ... this a big issue. Lots of old threads covering these things. You also need proper droop with your struts, etc. But, for instance Tein Flex's have won a number of National Championships and they are typically over damping and do not have much travel. Excellent driving over came those "problems." But the bar has been raised and better suspension components are being used.

Typically people start off with big bars and softer springs ... then go to stiffer springs and softer bars. 27 Whiteline is the way to go at first. Save yourself time and money and go with Poltec adjustable end links ... rather then trying three other types of endlinks first.

The winner of the STU National Championship used 245 tires on his thin'ish oem 7.5" wheels, while others where using up to 10" wheels ... so extra wide isn't absolutely necessary. 18" wheels are not the way to go. They are typically heavier, create more centrifugal forces (making for worse braking and turn in) and limit tire choice. Note that F1's don't use low profile tires.

Good for you to go to EVO School ... best Mod.
