you should get a decent wedge for your current elite ones too!
cant wait to find me a set
hint...hint 
I'm in two minds about those Elite wheels; part of me thinks that it might be sensible to stack them in the garage with winter tyres on, whilst the other thinks 'will I ever, in truth, put them back on once I've go the 19" snowflakes on there?'.
One thing I do know is that I'm going to give them a try for a month or two to see if I can handle the firmer ride or not before I make a final decision.
That sure does look good matey 
Do you need spacers as well?
My car has already got a 25mm spacer on each rear corner and 10mm spacer on each front corner which fills the arches a bit better. I tried the snowflakes on one side of the car this afternoon (leaving the spacers on) and they looked great. Very spangly, they're a lot brighter silver nowadays aren't they the newer alloys? My Elite wheels are very clean, but next to the snowflakes they looked grey.
