Bad idea. If you want the wheels further out, get wider wheels.

not necessarily bad, but not a good idea.
spacers will make your steering feel more vague the wider you go. 3mm is the widest you want to go on stock studs. wider than that you're going to need extended studs. |

1. Find tape measure
2. measure tire -> fender clearance. 3. Buy spacer 4. Profit. Duncan |

even at 25mm its only an inch wider on each side...would that really upset it?
i would think it should handle better the wider it is........ |

Imagine that you could extend the angle of the steering axis (SAI) to the plane of the ground. Then measuring the distance between the center of the tire and this intersection would give you the scrub radius. If the intersection is outside of the contact patch, we refer to it as positive. You could design a system with zero scrub radius and it would steer easily with no kickback, however it would provide almost no road feel. The impreza has some positive scrub radius, this increases steering effort, torque steer and kickback, resulting in greater roadfeel. It should be noted that race cars usually have some positive scrub radius for this very reason. The problem happens when you add too much. Thick of the roadfeel and kickback being a function of the tires leverage on the steering wheel. The further you move the tread away from the SAI, the longer the length of the lever. This will make the car trickier to control in turns and want to follow bumps on the road. Unfortunately for you, this problem will be much more problematic at low speeds, where you drive the car on the street. As I said in my above post, my race car is pretty horrendous at speeds below 40 miles per hour due to extremely low offset wheels, however since the car almost never goes this slow (other than driving around the paddock) it's not really an issue. The second issue with a significant spacer or a low offset wheel is the increased load on the wheel bearing. This is a pretty tricky one to measure. It will decrease the life of the bearing, however no-one can tell you how much. If you don't mind replacing them at a shorter interval this might not be an issue.

So true. I second everything Duncon said. I learned this the expensive and hard way. Spent lots of money on 35 offest wheels (thinking it''s no big deal it's only a few mm difference) that turned out to not only drive bad on the streets but almost impossible to align. You had to hang on with both hands becuase if the assfalut was uneven it would tear the steering wheel out of your hands. |

Increasing your scrub radius will give you MORE steering feel. Perhaps you are referring to running a wider wheel/tire vs. a narrow one. |
