About to throw on set of Rims.. Spacer question for Lexus

Hi there, I have 2003 lexus ls430 trying to get into vip style going on..
I've done research couldnt get right answer at the moment..
I'm about to order a set of custom adapters off a shop.

I came to conclusion of getting spacers Front size around...10-15mm and Rear size around.. 33~35mm

stock wheel setup is ( 7.5" Wide , ET45 245/40/18 )

New rims setup is ( 9" Wide, ET25 265/30/20 Front)
(10.5" Wide, ET36 265/30/20 Rear)
I try not to.. if possible not to shave/roll fenders. willing to change front tires if necessary.

I would appreciate your input. if im doing it correctly..
Thanks in advance guys
