Stock wheels, A couple questions Options

[Euphoria]

Hey, I'm finally about to pick up some good stock 15's for emergency wheels for registration and mountain runs/track. All I'm wondering is how is the ride on a harsh spring setup with a bigger tyre wall and smaller wheel compared to a 17 inch with a 45 tyre wall? as my Eibach setup is pretty bone jarring and I'm interested to see the difference, tyres on the stock wheels are 205/45/15.

Has anyone weighed the stock wheels?

Thanks.

The stock alloy wheels weigh 17 lbs. I noticed some differences going to the 17" scion tC wheels. Right away I felt like I needed to do an engine swap to push them. The ride seemed a little harsher too, but not by much. I put the 17s on before I lowered it so that was with a stock suspension. After lowering it the car felt a little harsher still, not enough for it to bother me though. I feel like it is more responsive.
