It's not a race car and besides, when these STI's with loads of suspension mods get beaten by the stocker..... I dont see the point. It fits my belief you learn how to drive the rear end off the car and it will reward you far beyond what you will expect it can. Almost no-one with a WRX ever truly finds out exactly just how far they can be pushed when you drive them the way they want to be driven.

The real thing that will make it work better is diffs. And I ain't touching THAT until..... lets just say there's going to be a lack of a VR4 for me soon.

And the loving legendary strut knock. That's gotta be fixed -_-

But really, unless your on a drag strip or on a big power circuit, it's already going to barrel into corners much quicker than the average driver can cope with. However, I'm not unfamiliar with what a tune can do, the other WRX I have access to is tuned for about another 20Kw with exhaust. It still doesnt tickle me to do it. Embarrassing the hell out of another modded STI sure does tho. Plus it's my daily driver and I'd like to have as little potential problems as possible

Can someone explain Subaru's priorities with racing programs?

They're doing ok in WRC, but seem to be really down to Mistubishi in PWRC, which is arguably a better measure of the real world quality of STis and the whole line down.

A lot of why the STI's are being beaten by the Mitsu's come to two things

1) Development

The EVO platform is much more developed with the older EVO's still in use. But then again,t eh older EVO's were still in the main a better car in PWRC form. BUT, the thing is, even if the new STI's are "new", they still should have plenty of tried and true hardware. So what gives?

2) Platform.

As much as loving retards like to bang on about Subaru wanting a hatch for rallying for performance reasons and the new suspension blah bla blah, those who spruke that don't know a loving thing. The hatch was pure and simple marketing. A hatch has it's own problems with weight distribution and COG. The other big issue is that the rear suspenion, which makes for a better ride is not suited for rallying. As much as the same retards bang on about struts being worthless, the simple fact is stuts are EXCATLY what works in rallying. Yoo need suspension travel. You need the rear camber to walk about to allow weight shift to really come to the fore. There is thence a real fundamental issue under the STI's skin that will take a lot of thinking to solve. When i was in Finland, I really noticed that the EVO runners had one solution for suspension design and it worked. The STI runners were all quite different with springs, shocks and suspension rates. It seems they are having some problems working out what to do to get the rear to work.

The problem is, there is no time. The EVO X is looking like a right weapon. A few of them are starting to appear and they are instantly fast out of the box. It being a sedan with a suspension that suits rallying means I would expect the EVO X to be the car to have in PWRC next year.

As much as we are Subaru fans here, we all have to admit the EVO X really stole a march on the STI. It's just plain better, full stop.

You're going to have to explain to us loving retards why the Citroen C4 does so poorly in WRC and why the Ford Foci hatchback seems to be doing pretty terribly in WRC where oddly enough Mitsubishi doesn't even compete anymore.



Maybe because the point that goes over your head over and over again is that the hatch was always a marketing decision and that a hatch HAS no real advantage. None.

Mitsubishi dont compete because they didnt give a team money. They kinda dont have any to give to WRC.

Subaru didnt do as well with the sedan because of two reasons...

1) Cubic cash. If you decided to take a trip to Europe and scan the service parks, you will notice the sheer size difference and hence budgets Citoren and Ford has over Subaru, not to mention Ford basically have 4 teams they use for development, Citroen 3. Subaru? 1.

2) Awful design. Prodrive designed the 05 based on sports sedans and not a rally car. Whoops, that will be three years down the toilet until they worked it out. The 08 is the first car properly designed. On that awful design, the boxer motor may be good in a road car, but in WRC where you can do freaky engine positioning, the boxer is too far forward.

Now in countries that have more money and teams that know a great deal more about rallying than the USA, the EVO IS the better car. And so far the new STI is not able to beat the old EVO's (looking rather doubtful too, given in Finland how many Mitsu's were beating the first Subaru until the drivers had brain fade), while Mitsubishi runners have the new EVO X coming.

Hopefully this is the last derail: Tell me more about this freaky engine positioning with the power of words and pictures please.

The Ford / Citroen's WRC engines are quite some distance back from the front of the car and a lot lower down than say you would find in a road car. They basically manage to package the entire engine / gearbox to very close or behind the front axle line so there is very little foward of the axle. The Subaru engine is unavoidably more forward.

You just cant do WRC engine placement in a road car however - So while a Subaru road car boxer layout is very good for a road car, nice and low with the weight back (and PWRC too), it's got a bit of an issue in WRC. The boxer cant really go that much further back and you cant really move the layout all that much.

And enough of that anyway.....

The intention was to get an 01, then do a panel swap so it becomes an 06/07, then get a engine out of a front cut, which only works if I can find a cheap 01. Hell, it'll almost be cheaper to just get another 06 outright. That certainly has crossed my mind.

Otherwise, see if Ralliart has the rally deal still going where you can get a race/rally only import EVO X with cage. I heard they are only 41K. At least it'll be half built as well.

Oh god, dealers. Im used to changing spark plugs on small I4s, which take all of 15 minutes. At first glance the boxer looked much more tedious. I decided to ask the local Subaru dealer during an oil change how much they charge for changing the spark plugs, "The spark plug change is $300." My jaw literally dropped infront of him. "Oh, its because the WRX uses SPECIAL PLATINUM spark plugs, theyre advanced." I was really fighting back telling him I wasnt retarded.

Actually I think the plug change cost that much because it's a bitch to do. Any boxer motor however, a plug change is a bitch.

Anything else on the car tho.... oh what a nice thing to work on. Had the suspension out to get rid of the dreaded strut knock (strut knock isn't dying struts, it's actually bad lubrication) and to do some other work that I'm keeping unspecified at present - and really, everything is just nice. I do have to make a tool to make takign the strut tops off easier but it's all good.

Also was really surprised just how easy it would be to turn an 06 into a race car. Noticed a few nice touches that would make a conversion soooooooo easy...... and a lack of things getting in the way. There is also IS quite a handling difference between my 06 and the 07 I also been driving about in. Prolly have to have a good look this week when both are up on jack stands.

Straightline, I think the XT will get the WRX up to about 120kph but after that the WRX walks away.

Handling wise, the Forester is more limted by tyres. Get rid of the Geolanders, theya re terrible. If you are a lunatic, a XT can be thrown into corners a lot harder than it looks it should have any right to be. WRX will still blow it's rear end away tho.

You can drive them drat hard and they will keep going. I've been known to have all four brakes and exhaust glowing red/orange after a decent fang - Plus the gearbox is definatly stronger than a WRX's.

The g/f went to an offical launch of the 09 last night - I got there late so I could only have a quick look.

The sedan is.... not too bad in the flesh. A VAST improvement on the hatch. It has split fold rear seats even but a very odd kick in the boot that will limit the size of anything you want to put through.

There is definatly some good handling improvements, 195Kw as standard as they put the STI turbo on AUS delivered WRX's, wider tyres and if I heard right, the rear diff is once again got an LSD in it. Piss tiny intercooler, wich lead to all sorts of "Why the gently caress is the scoop so big for that?????"

Subaru I think gets it that the 08 was a fuckup. The 09 looks to me to be as a sedan at least a pretty tidy improvement. It even looks decent from the rear. Front is still ugly but okay, it's better.

An 08 may become very cheap second hand. The 09 sedan is what they should have had to begin with.

Are you sure it's not the VF52 turbo? That's what is on the USDM 2009 WRXs. It has similar components to the STi turbo, but it is not quite the same. I think it shares a compressor or impeller but not the other. Something like that.

Just quoting what they said from the podium. So my words aint no gospel.

However from the mouths of Asia-Pacifc rally crews in the room, there was a degree of talk about the 07 vs 08 vs EVO's. Consensus was that the 07 is definantly the best handling, the EVO more power. The 08's have some real suspension problems that Tommi Makinen's organization are making "good progress" on finally. Because the suspension is short in drop, the tuning sweet spot is v.hard to find and it's very narrow in settings range. This means that the 08 works for only certain road types.

Apparently the 09 has some changes that address this issue. The Spec C "apparently" is being changed too.

An 08 of all things is looking like the cheapest to use - the rear suspension after a tear down and look at isnt really to my liking. I can just read problems all over it. But for what I have in mind, new is going to work best for the sake of homologation longevity and I just man up and deal with the issues.

I've done a few SCCA autocross events, but rally is what it's all about. The one rallycross event that was held in my area was a blast and I managed to make it out of there without any damage. I want to do more rally events (I'm looking into Formula RallyX at the moment) but since it's my daily driver, I'd like to minimize my destruction / downtime.

What kind of parts would you guys recommend for sustainability in desert rally events? Speed isn't my concern at the moment - I'm not experienced enough to need more power.

Going back here, as another observation, using your DD for this is a very bad idea. I would strongly urge you to not do it. It's quite normal at our club events for a WRX to be towed away due to something breaking - granted 30 odd WRX's means the chances of a tow away are higher than when one or two WRX's but I simply would never use my DD in the line of constant fire. You will wear it out prematurely, you will eventually break poo poo and dirt will get everywhere. On a car whose only purpose is to get dirty and to take the risk of breaking and being towed home, its not an issue.

In fifteen years, I towed home a RWD / FWD once. In four years, I towed home the VR4 4 times. I'm expecting the STI to be towed home with the same regularity. Granted I do kick the living poo poo out of the race cars but that's what they are for :)

On the 08 vs 09 -

I'd agree if you were going to modify, an 08 would be the best target. Your going to toss most of the things that make an 09 better in the first place and 08's arent holding value all that well so get the cheaper base and use the difference to upgrade more. If you dont want to mod, then there's no argument, 09 is the way to go.

Personally, an 08 WRX might well end up being the best one to grab for modders, just simply because of the unloved status, resultign in lower initial cost. I was seriously looking at an 08 and then doing a Group N conversion to it - you can grab 08's with gently caress all kms here for 3/4rds new price, then just go to town. As a racing base where you have to strip poo poo out anyway, an 08 will simply rock. And in fact I was about to get one before the STI popped up at a dont argue price. Even if the 08 has issues in race / rally trim, if you want a basically new race / modded WRX, it's not a bad option at all.

Was also looking at an EVO X too but.... ugh. Big. Unweildly. No thanks.

With the locked differential, all the torque goes to the rear wheels. The torque bias is dependant on the traction, since the motor cannot produce torque without an equal amount of resistance from the tires. So, all the resistance is done by the rear tires, none is done by the front, and so the torque split is 0:100.

With the diff locked, the torque will go 50:50, no matter what the surface front or rear on. It's exactly the same for any diff.

What the 50:50 will mean is that your front wont bite, but your rear will and hence you will get going. Even if the front had utterly no traction at all, 50% will still go there. That's what diff locking is all about. Atomicfire has it correct

notice how in my example the diff is at full lock?

And yes, with a completely locked diff the torque is sent to the wheels with traction.

you guys seem not to understand how differentials work.

Yes exactly it is at full lock.

In a completely locked diff - the torque still goes equally to the front and to the rear. Disregard what the effective work it can do, that is not the issue when you are discussiong torque split. Torque goes to both front and the rear equally when there is no chance front of rear axle can move independant of each other.

How much effective work can be done is very different. And where that work is done is different, this is true but it's not axle torque split. What you have in a locked diff is effectively a four wheel axle. In fact, lets go to the logical conclusion and lets say you have a four wheel truck axle. Two wheels a side. The outside wheel is tarmac, the inside wet ice. There is still 100% of torque availible of that axle going via both wheels - if one has traction and the other doesnt, they still have the same torque turning them.

So what does this front torque actually do if there is no traction on the front but lots on the back? Well.... nothing. It's wasted. BUT because the diff is locked, there is torque availible to drive the wheels with traction. And thence the car will still move. IF the diff was open, the torque will go path of least resistance and you will get a flurry of front wheelpin, no matter what the base torque spilt is.

Front and rear will be trying to do the same work. Wether that work is achieved..... different story.
