No disadvantage on the street, except for the tires will be more expensive!

Advantages that I felt in the real world? Quicker turn in (extreme difference), quicker steering, less bounce from the tires, less lean in corners, more grip! Pretty much an improvement in everything a tire should do. Better looks too.

My WRX wheels are 16 lbs too, not 12 .

poison: the benefit you are feeling is not necessarily of going to a larger rim, but becuase you went w/ a larger rim, you had a smaller/stiffer sidewall tire

if you kept the 15 but went with a smaller sidewall you would feel the same improvements

Hi Gopal(if u are who i think u are)! the biggest improvement is getting different tires. bigger wheels is 75% cosmetic. u will get a bit more NVH(search to learn more) on a +1 or +2, but having higher performance tires the difference is immense. being abel to switch back to winter tires on the smaller wheels is a huge benefit too in NY.

Bigger contact patch = more grip and less gas efficiency.
Shorter sidewall = less sidewall flex, stiffer road feel. Old cars used to use high sidewall tires as a "secondary" suspension. They really soften the ride. Modern suspensions are much better, and afford a car owner the luxury of low profile tires.

Of course


But 15's with low profiles would throw off the odometer, and look, um funny on this car. The idea is to keep stock diameter, unless there are special needs for the track, weather, etc.

12 pound wheels will help acceleration, braking, turn in, overall grip (on all but a perfectly smooth surface), and last and least important- they look better. You might also notice a gain in fuel mileage, due to the less rotating mass you are accelerating. But if you are like most of us you'll just accelerate faster and not gain any mpg.
