Default 2006+ WRX in STU - How'd you do this season?

I just wrapped up my first season of AutoX running my '06 WRX Wagon in STU. I wasn't that competitive, but wasn't expecting to be due to my noobness. How did all of you '06ers running in STU do this year? Just wondering, since the car seems to be up against some stiff competition (EVO, STI to name a few)...

I'd also be interested in hearing general thoughts on the competition and how the '06 stacks up...

I think the WRX TRs may have a chance. The 2006MY STI weighs 3351lbs, while the WRX TR weighs 3192lbs (the WRX Limited weighs 3239lbs). Considering the WRX TR weighs about 160lbs lighter than the STI, it may have a chance in the transitional turns. However, at the exit acceleration of the turns forget it; the STI has 3 LSDs and better power and a 6 speed ratio gearbox.

I don't have hard evidence either but, I would like to add. The 5 speed could prove an advantage on fast courses requiring use of both second and third for STis. The WRX also has peak TQ at a lower RPM. I don't think it ever stands a chance, but it has a couple of advantages coupled with a ton of severe disadvantages. Go play in ESP, but don't get us bumped to BSP kthx

FYI, the regular WRX with fog lights, auto HVAC, etc. weighs 3192lbs. SOA never posted an official weight for the TR. However, Motortrend magazine recently did...




3,140lbs!!!

I saw that mag. Unfortunately, I wasn't sure if that was a typo or not since the Mazdaspeed 3 also weighs 3140lbs. Thus I used cars101.com for the source. I can't think of a reason the WRX TR is lighter than the WRX except for the seats. I don't think the weight difference between the seats are 25 lbs, which would make up the greater than 50lb difference.

I didn't think Joe Spitz weighed each model - he would just use the info Subaru lists (notice the regular WRX sedan and TR have the same weight). According to Subaru's media site, the weight for the TR is 'N/A'.

So what would account for the 50lb difference between the WRX TR and the WRX if MotorTrend did not have a misprint?

Stereo? Probably 10 pounds could be found there.... and I doubt if the seats weigh any different.

<Stereo> TR just has an 80 watt 4 speaker sound system with a single disc cd player - WRX has a 6 disc in-dash cd changer with a 140 watt 6 speaker sound system.
<Fog Lights> TR has STI covers, WRX has two fog lamps and the necessary wiring, switches, etc.
<Climate Control> TR has manual system, while WRX has an auto climate system requiring a control module to regulate everything.

Painted mirrors on the WRX will be neglible and like you mentioned, I doubt there's any difference in seat weight. The wing is technically an option on both cars.

FWIW I weighed mine in street trim with about a half a tank of gas at 3120.

That's about right since we have ~16 gal gas tanks. 8 gal gas = ~60lbs.

P.S. When you weighed it, were you on those lightweight wheels? That could account for the missing 12lbs.

That's awesome. I'd be interested in knowing the exact weight they got for each car. I know that when Motortrend test cars, they ensure they have a full tank of gas and are set to maufacturers recommended specs (tire pressures, etc.)

This was my first season of autoxing and I began it with a brand new bone stock 06 TR properly broken in. As the season progressed, I added mods here and there, trying to keep it balance between power and handling. After a year of events, Along with improved driving skills,and a host of basic mods, I've find myself consistently in mid pack amongst a pack STIs and LGTs.

I'm just amused that you think MotorTrend even actually drove the cars they review much less weighed them.

I've subscribed to Motortrend for years, and used to watch Motortrend TV when it was on the air. They're anal about that stuff.

It will stack up this way...go back to DS or move up to ESP (with ALL mods available and legal) and you'll have a better shot at winning. I'm not usually that blunt but I figured I'd save you some frustration. That said, feel free to prove me wrong.

Great joke! Considering STIs have won the STU category for the past 2 years at Nationals. In all due fairness though, I wonder if there has been serious efforts by an Evo driver.

The service manual lists three Curb Weights for the 2006 WRX 5MT Sedan:
3192 (base model)
3234 +sunroof
3239 +sunroof, +rear spoiler, +ColdWeather package, +leather seats

No reference to the "TR" package which should lose some weight off these specs.

I'm not frustrated at all, just curious to see how some people have done.

Between you, Corey, and Andrew all potentially running Evo's in STU next year, the Subaru's will certainly have their work cut out for them.

Dave,

I'd have to disagree. The '06 WRX can run almost any coilover suspension that an STI driver can use. Branden Burkhart mentioned he makes ~304whp on his STU legal race gas ECU map. I'm sure '06 WRX owners could make ~250whp and almost an identical amount of torque (as a VF39 STI) on a good race gas STU legal map.

The WRX will have to make fewer shifts, and have a good 200+lb advantage over an STI driver. And being down 50+whp means diddly on an autoX circuit, as some cars make less than 200whp and are still up there in the trophies (Mike Neary's '95 M3 makes 195 rwhp).

The STI's success means diddly IMHO. The same driver won both times - Burkhart. If he'd been in an Evo the last two seasons, guess what? No STIs would have won...

Agreed. The difference in Stereo, Climate Control and Fog Lights should definitely make the TR at least 40+lbs lighter than a regular WRX.

Not really sure what that means...

And identical amount of torque, at an identical RPM equals an identical amount of HP.

The only think you seem to be saying is that the peak torque of the WRX could be the same as the peak torque of the STi. That really doens't say much, only that at some random point (different in both powerbands) the cars will make the same horsepower.

Why do we differentiate between torque and HP? If a car has more low end torque, it has more low end power. If it has more low end power, it has more low end torque.

Seems more appropriate to jsut say they have nearly identical midrange power.

CN: why when the tach falls below 5k do we call power torque, and vice versa???

Sorry...bored at work...

It is sad to see all of the Suby pioneers, at least in the Philly region, move on....they will be missed.
