They are a bit heavy in 17" but a decent quality wheel.
Lighter weight wheels will improve all aspects of performance and make the car ride better, less wear on the chassis as well. Also 16" wheels and tires will ride better, Konig makes a wheel called the Maxxim Winner, 16x7 is under 17lbs, very well made, less than $400 a set.
