Hey so i'm new to this forum and going through some of these posts make me feel sooo behind, these forums wouldve cleared up many headaches had i known to join earlier!
So i have a 2008 g37s coupe and its lowered. I have really skinny wheels on right now and i want to go as WIDE as possible. What are the widest wheel specs that would fit on stock ride height and my ride height right now? I hope the picture i attached will help give an idea to how low the car is. My wheels rigbt now are 18x8.5, 225/40/18 with 25mm spacers. I'll appreciate any help i can get, thanks!
