Hey everyone,

Will this fit a Gsedan... front 18x8.5 +42 and 18x9 +33

Also can I use my 245 40 18 tires on this setup?

 

It'll work. You'd want to get a 5-10 mm spacer for the front as they'll be a little tucked with that offset. For the rear, you'll need to run -1.5 camber to make it look right. I have an 18x9 +27 with a 225/45/18. The wheel sticks out about a half inch but the top of the tire is perfectly flush with the fender at -1.5 camber.
