STANDARD STABILITY CONTROL
For 2009, the Subaru stability control system – Vehicle Dynamics Control (VDC) – is standard on all Outback and Legacy models except the Legacy 2.5GT Limited with five-speed manual transmission. The system helps to prevent skidding due to understeer or oversteer by managing individual wheel braking and/or reducing engine power to correct the slide. This system adds to driver control of the vehicle, improving active safety.
Fantastic! 2009 it is - even if it's more money because it's an `09 and not a leftover `08, VDC appears to be well worth it - I mistakenly thought it was JUST ASR (which isn't new technology).

Wonder why they didn't put it on that one single model? Strange. Maybe they wanted one model where people who did not want it to have an option.

when Subaru first offered a ESC as a standalone Bean VDC model , it was always coupled to the VTD system and I recall discussion then that the VDC could not be done on a stick shift but they are offering VDC on the stick shift Spec B!! I this purely marketing or is there some engineering issue?

It's a marketing term. I bet the hardware varies between models and depending upon the AWD system in place.
Shoot, early on, it was a model name, too, i.e. Outback VDC.
#234 of 258 Wheel/Tire sizes & Oil changes
Jul 11, 2008 (6:33 am)
I recently purchased (and enjoying) a 2008 Spec B. Looking for comments/answers to the following:
1. I will be purchaing a set of winter wheels/tires. Are there any issues going to 17" wheels with 205/50/17 tires? (the speedo reading will be off by 2.1%, which I think is within an acceptable range)
2. When it's time to replace the stock summer tires, will 235/40/18 fit the stock 18" wheel? Any clearance issues going to this option?
3. Re Oil changes. When is it appropriate to start using synthetic oil for the 2.5 turbo engine?
Also, would Castrol 0W30 or Mobil 1 0W40 synthetic be okay to use rather than the 5W30 currently suggested in the owner's manual? (I use the Castrol and Mobil 1 in my A4's 1.8T engine, as these appear to be the 'best' oils for turbos to prevent sludging.)

What I've heard on the forums:
Better to go to a synthetic sooner than later. I'm pretty sure Mike (Paisan is his user name) has said some gasket problems surface if you use conventional for a long time then switch to the synthetics (because synthetics are smaller, uniform molecules and they slip through the gaskets since the gaskets are "used to" the larger molecules of conventional)
Reference the different wheel sizes, if your speedometer is off, then most likely your odometer would be off too. This would affect the mileage on your vehicle.
I personally haven't switched to a purely seasonal tire, I prefer all-season since we only have a few days of bad snow yearly here in New Jersey. The rain is more of the motivation behind purchasing a new `09 Legacy.
#236 of 258 2008 Legacy GT 2.5 MT exhaust and cold air intake
Jul 11, 2008 (10:22 am)
I am thinking of adding the Subaru hi performance exhaust, cold air intake and heat shield to my 08 GT. I know this is subjective but is it worth it? (about $1500 installed) I have been quoted 30 HP and 30 ft-lb torque increases. How loud is it going to be around town and highway cruising? Does it increase dirvability by bringing the torque on earlieer in the rpm range? Thanks in advance for your input!

Ok a few answers for you guys...
On the Snow Tires:
I'm in NJ and use summers and snows.
If going to summers I wouldn't go narrower than 215-45-17, as that's stock. I run Nokian Hakka RSi snows and they are GREAT in the snow/slush/rain we have here in NJ.
On Synthetics- I would wait to 5,000 miles before switching and wouldn't switch after 60-70k of regular.
On the SPT Exhaust, I have it on my 05 wagon, it gives you a bit more power and throttle response and has a nice tone. I happen to know the manager of SPT who designed it and it's a nice unit. The actual increase is 12hp/15lbs of torque at the wheels, so not sure the 30/30 is correct at the crank or not.

Thanks Mike and pilot1226 for your responses.
I have seen excellent reviews on the Nokian RSi, so I will definitely keep them in mind when choosing a winter tire.
I will wait until the second oil change to convert to the synthetic.

Do you have the high flow air intake and heat sheild as well as the SPT exhaust? The parts guy at the local dealer gave me the SPT brochure and that's where he quoted the 30 HP and 30 ft-lb increases for using all three products together.
