1/2 Incorrect - The steering angle sensor for VDC on automatic vehicles will activate or throw a DTC if the angle is more than 10 deg off without a variance in wheel speed left to right - front to rear. I see it when wrecked vehicles are repaired at a body shop and are driven without the zero point reset. |

The recommended tire pressure is a compromise for comfort and performance. The tires are rated to 44psi, and while they will likely change in shape somewhat by increasing air pressure within these numbers, it is not likely to be hugely significant to the point of changing the tread life. Traction is also a relative point depending on conditions. If you are running higher tire pressure you may experience slightly less traction but it is not likely to be a very significant difference unless the tire pressure is massively higher. I believe the Mazda 3 ( a lighter car) uses the same tires as this car but recommends a tire pressure of 36 or 38 on the door sill (had to adjust a friends tire pressures recently).

That is correct, however, if I was doing an alignment on a vehicle equipped with a steering angle sensor, I would re-calibrate it automatically....so my previous statement stands. |

i typically run tires at higher pressures than what is recommended, even 3psi over will greatly reduce the innermost treadlife. the last 2 set of tires I have had on my buick i ran at 38/36 when recommended is 32/30. the innermost tread was to the wearbars when the outer 2/3 still had 5/32" remaining. it makes a difference. like i have stated before, i have tested higher pressures and on the stock yokos i don't see any reason to run over 35psi, the tires just can't handle it and i got signficantly less traction. i didn't notice much difference in steering feel, but the speed at which the tires breaks loose is lower with more pressure |

I did notice the Dealer had changed it from my usual 34psi to 38 psi when cold last service but I dropped it back to 34 next morning, I'll try upping it to 38 just to see but I don't see how it'll get rid of the 1 inch dead spot on centre.

I lowered my air pressure to 38/37, and honestly, it doesn't feel as good as it did now. I'm the kind of driver that likes to feel what the car is doing and the road, so 40psi helps with that. Obviously, it also affects traction depending on the conditions of the road. Beyond that, the Mazda 3 is a lighter car with the same tires, and a higher air pressure is recommended from the factory. The interesting point here is that in reviews, the Mazda couldn't hold the skidpad or stop as well as the Subaru, and I wonder if it has to do with the car or with the tire pressure, and how they were tested. The suspension is indeed completely different so that at least is a good point against overinflating, but at the same time I can't imagine it would wear that badly on the shocks would it?

That actually depends. It does feel like it handles better, but Car And Driver found the Impreza had a higher skidpad speed and other tests have found the Impreza to actually handle better at higher speeds. The Mazda is faster though, helping it appear to handle better in some tests.

The question is: Does the Mazda3 handle better than an Impreza with a 19mm RSB?
My stock VW TDI handled better than my stock Impreza Sport, but that was no longer true after I upgraded the Impreza's RSB to 19mm. Actually, let me clarify. The stock TDI cornered flatter than the stock Impreza with the 16mm RSB. But the Impreza with the 19mm RSB corners flatter than the stock TDI. However, even with the 16mm RSB, the Impreza had more traction than the TDI when cornering, especially when the road surface was less than perfectly smooth. On bumpy roads, the TDI's rear end felt like it was getting loose, whereas the Impreza stayed more planted even before the RSB upgrade. |

Have you driven a car with electric steering before? It's a little different feeling, took me a while to get used to it.

When replacing my wifes '04 Mazda 6 we test drove the Mazada 3 back to back a few times with the Impreza, the 3 certainly felt sportier therefore felt it handled better however the Impreza handling was still good and the ride was more compliant ie more like the 6 whereas the 3 was choppier on iffy road surfaces so the Impreza got the nod feeling more like a 6 than the 3 did. |

I just got my 19mm STI rear sway today and I'm really looking forward to installing it.. quick question tho, is this a component where torque specs are important or can I just crank it down solid and be fine? I have an expectation that the answer is that its ok, but I don't want to be naive so I figured it was worth asking.. Thanks peeps!

Just snug it hard with a short socket wrench. If you use anything with a long handle, it had better be a torque wrench, or you'll overtighten.

If it knocks around and makes noise, tighten it a little more.

^ niiice. thank you! I'll torque it on the high end and hope to avoid the clunking others have experienced.

tenaciousZ, any improvement with the RSB? Anyone add the sway bar to their 2012+ base Impreza, or come up with another solution (other than ditching tires early). I've noticed this on my wife's 2013 wagon premium, which I assume does not have the RSB. It drives me crazy, but thankfully she does not mind it so much.
Regarding installing the RSB + linkages, does this require a lift? How involved is the install? |

I don't know if it is true or a dealer didn't know what he was telling me, but I was led to believe that the power steering pump is electric, rather than belt driven. (An electric pump moving power steering fluid through the system.) The amount of force needed to move the wheel has nothing to do with the type of system. A buddies '69 Coronet R/T 440 steered so easy you needed 1 finger for anything you wanted to do. No feel at all because it was so over boosted. As for steering input, my '03 REX was always very precise, as is my '13 premium. Using a light hand on the wheel seems to be better than using a death grip, for lack of a better term. I do notice a change after swapping the stock tires out for the winters, or vice versa. After a day or two, I really don't notice it any more. (It seems twitchy until I get used to it.) I might suggest a tire rotation, to see if something changes. (Tire pressure was already mentioned.) Perhaps take an independent shop, and ask them if they would check the alignment. John |

Sounds like alignments are needed
