A wider wheel track means better traction, hence increasing body control experience, offering better corner performance, and more stable driving. With the Marquis spacers, you can fill the gap in your Marquis fenders and get a more aggressive and powerful look. Finishing with 0.02mm tolerance, BONOSS wheel spacers fit more perfectly to the wheel hub, which means reducing high-speed vibration, offering a smoother driving experience.

13. Why do you need wheel spacers for BBS/Work/HRE/Rays/OZ wheel rims?

Truly, hub-centric spacers are around as important for aftermarket wheels as lug bolts/nuts are. An excessive positive offset will cause the inner edge of your rims and tires to rub against the suspension components. In this case, wheel spacers can create the desired clearance to correct the offset by pushing the wheels away from the vehicle hub. They can also be used to change the bolt-pattern and center bore diameter of your Mercury Marquis. These items function as BBS wheel spacers, Work wheel spacers, HRE wheel spacers, Rays wheel spacers, OZ wheel spacers, and Enkei wheel spacers at the same time.

Higher-performance brake kits are often bigger than the stock parts. A wheel spacer makes required room for a larger caliper that wouldn’t fit in the factory wheel space. By pushing out the Marquis wheel, you can gain the ideal amount of clearance for a bigger brake caliper instead of rubbing against it when mounting back the wheel. If you have upgraded your brake system with bigger brake calipers and need to fix the clearance issues, proper Marquis wheel spacers will be your instant and cost-effective solution. These items function as Brembo wheel spacers, EBC wheel spacers, Wildwood wheel spacers, AP Racing wheel spacers, Endless wheel spacers, and Power Stop wheel spacers at the same time.

16. Will wheel adapters allow my Marquis to install OEM wheels of other vehicles?

BONOSS offers a huge range of Marquis wheel adapters to fit a massive variety of different vehicles. Common requests from our customers include PCD conversion, CB conversion adapters for other vehicles’ OEM wheels, or aftermarket wheels (e.g., 4×108 to 4×100 wheel adapters, 4×108 to 4×114.3 spacers adapter, Marquis 4 lug to 5 lug adapters).

Done correctly, your excellent modification will be advantageous. For more details, check on Do You Need Wheel Spacers or Wheel Adapters.

17. How thick Marquis wheel spacers do I need?

Here is a simple method: use a straight edge such as a 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 line. Too thin, you will still have wheel/caliper interference. Too thick, and your tires will hit the fenders. Use proper size of spacers not only ensure safety but also avoid breaking your local laws and regulations. Common requirements like 2-inch wheel spacers Marquis, 1-inch wheel spacers Marquis, 1.5-inch wheel spacers Marquis… Currently, BONOSS provides 15mm-50mm thickness spacers to meet your needs.
