same reason with the 350z's, people just don't like the idea of 20's on our cars. The reasoning behind it is performance mainly. However, I rather have forged 3 piece 20's over alot of these 1piece or 2 piece 19's people put on. Its all a matter of preference. I had 20's on my old 350. 3 piece forged wheels that look great on a car...I fail to see the problem . Just my two cents.
