Personally, I think you are asking for trouble.
Assuming you have 225/45x17s now, you'll need a 225/30x20 or 235/25x20 to
keep the overall diameter at about the same as you currently have.
Your sidewall height will go from just under 4" to about 2.5". The 235's
will give a better result from the perspective of gear ratios and speedo
accuracy -- although the speedo is slow now, and it will be a bit more slow
with the change. The 235s will fit the back okay (if a bit tight), but I'm
not sure they will fit on the front.
Troubles with gear ratios notwithstanding, I think you are asking for
serious problems with a loss of 1.5" of sidewall.

Don't US cars come with wheels? I have always found that stock wheels are just
fine with stock suspension and the Bling factor will only make it more desirable
to thieves. In the UK insurance premiums rocket skywards when aftermarket
wheels are fitted and engine mods are really a no-go unless one purports to be
in the "TRADE" with trade insurance - this allows one to drive any piece of gold
or crap they have a licence for.

How does an insurance company find out -- and why do they care --
about aftermarket wheels? Do your policies require that you report any
modifications to the car? That is not the case in the US.
