Hey guys, Im looking to buy a set of wheels for my 2008 G37S with stock 19" wheels and have a set of winter wheels and tires while decreasing to 18" wheels to increase handling and save cost of switching out the 19's every year. Can anyone give me specs and sizes on wheels i should look for, biggest concern is to clear the big brakes and also what tire size best fit their needs? Thanks all

 

Enkei RPF1 18x8.5 +30 offset, these weigh only 18.3 lbs, clear the BBK and will be a better flush fit for your coupe, I'd run 245/45/18s all around.
Tirerack has these for $279 but you have to enter a G37 Sedan w/ sport package since it won't allow you to select smaller diameter wheels than your coupe came equipped with.
