^^ Its only +1 for the 370z as it comes with 19's. Everyone liked 19's on the 350z eventhough it came with 18's. Even the "all about performance" guys did the +1 size 19's on the 350z. Agree these rims look small with those huge wheel wells. 21" do fill it out nicely from what Ive seen and its only a +2 but less advantagous for performance.
Anyway dont like the rims and it seems tucked in to the body instead of flush. Why doesnt anyone that fits wide wheels/tires to the 370z not post up shots from the rear so we can see the width of the tires compared to the body
