I'd like to upgrade my suspension and brakes a little on my 2000 OBS. I just have a couple questions:

1. I'd like to put on lowering springs but they usually make them for an RS. I know they'll fit but what kind of ride height change will I get? What I mean is, if the springs are meant to lower the car 1.5", will these springs lower my car the same or will it lower it even more because of the increased stock ride height? I mean, will my car be at the same ride height as an RS with lowering springs or will it still be half an inch higher?

2. Will aftermarket rotors like Powerslot or something made for an RS fit or will they be too big? I'd like to just get some better rotors and pads using my stock calipers if possible.

Thanks in advance.
