keep looken dave IMHO 19" look the goods but if your cars a daily driver forget it, not worth the hassels.
If the 19" do turn the ride right off, you are going to be stuck with them for a little while untill you can unload them & get some smaller wheels.
What size tyre are they going to give u in the package? I can do some checking & find out what a middle of the range set of performance tyres is worth, if you like????
Just PM me if so & I could also get you a better deal on wheels & tyres
Cheers Mike
