Although aftermarket wheels and tires are designed to enhance the exterior and performance of your vehicle, when copping your new Nissan 400Z some new rims and realizing they’re not sitting quite so flush in the fenders as you’d hoped, wheel spacers are sometimes the perfect solution to your fitment issues. The Nissan 400Z wheel spacers have widely used as a cost-effective practice among many racing enthusiasts. They are designed for adding more backspacing while providing a sporty look. Keeping the backspacing correct allows enough room for your suspension, brake, and steering systems to operate without interference from the big wheels and tires. With various thickness 400Z wheel spacers, you are able to control how far out your wheels can be. This is not only to solve the problem of the wrong offset but also more effectively end the hitting of the wheel on either the brake calipers or coilovers. There are a few things that can help you quickly find out which 400Z spacers you need. (Above photos from https://www.nissanusa.com/)
How to Measure Nissan 400Z Wheel Spacers?
Some 400Z owners only intend to push their wheels out a bit for the ultimate fitment, a smaller spacer such as a 15mm may be sufficient, others may need a 1-inch or even 2-inch aero spacer for completing the look of a widebody 400Z. If you have added those sexy aftermarket wheels, make sure you have Nissan 400Z spacers of the proper thickness to correct the wrong offset. There is a simple trick to figure out how thick spacers you need to get the wheels flush the fender. Preparing a straight edge metal ruler, place the straight edge on the outermost part of the rims where the wheel comes closest to the fender (preferably the top), then, measure from the outside wheel to the straight edge. This distance is the size spacer you will need to achieve the look that flushes or nearly flushes with the fender. If you had clearance issues at the brake, then the thickness depends on the increased height of the caliper. If it is the rim ET/offset issues, then the thickness depends on the change amount, for example, your stock wheels’ ET is 40, you would like to install an ET 65 wheel, then you need 25mm thick spacers to correct the wrong offset.
