Okay, planning on getting 18x8.5 for the rear and 18.7.5 for the front. Is that a good set up? And what offset should I get for the front and back? They also have an option for 18x9.5...Or is that too wide for the S2K? thanks!

 

I would go with 17s over 18s.

Go

17x7.5 +52 without a BBK +42 with a BBK
17x9.0 +65 through +68
