11. How do Alfa Romeo 155 wheel spacers affect handling?
Wheel spacers bring your 155 rims and tires outwards, increasing the distance between the left wheel and the right wheel. And most track racing cars would make use of every millimeter of the wheel-wells space available in their design for the highest performance and the best exteriors. A wider wheel track means better traction, hence increasing body control experience, offering better corner performance, and more stable driving. With the 155 spacers, you can fill the gap in your 155 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. For more details, check on Wheel Spacer Handling Improvement.
12. 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 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 Alfa Romeo 155. 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. BONOSS has thousands of successful cases of manufacturing spacers for aftermarket wheel rims issues. For more details, check on When to Use Wheel Spacers for Aftermarket Wheels.
13. Can wheel spacers clear Brembo/EBC/Wildwood/AP Racing big brake kit issues?
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 155 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 155 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. And for safety and quality, purchasing from a professional manufacturer is trustable. BONOSS has thousands of successful cases of manufacturing spacers for big brakes issues. For more details, check on When to Use Wheel Spacers for Big Brake Kit.

Generally, widebody builds include the upgrades of larger-size wheels and bigger brake kits. The Alfa Romeo 155 wheel spacers allow you to add larger wheels. You can also add larger brake kits, which is a great safety upgrade especially if you plan to take your widebody 155 onto a track. Installing wheel spacers is one of the easiest and most cost-effective options to get low and wide as well as to get flush the aero kits fenders. These items function as Mansory wheel spacers, Hamann wheel spacers, Veilside wheel spacers, Brabus wheel spacers, Liberty Walk wheel spacers, and TECHART wheel spacers at the same time. And for safety and quality, purchasing from a professional manufacturer is trustable. BONOSS offers various thickness wheel spacers to meet your needs.

15. Will wheel adapters allow my 155 to install OEM wheels of other vehicles?
Wheel adapters (also called rims adapters, lug adapters, or PCD adapters) are designed to change bolt patterns, center bore diameters, and correct wheel offset in order to properly install wheels that are not specifically made for your car. BONOSS offers a huge range of 155 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., 4×98 to 4×108 wheel adapters, 4×98 to 4×114.3 wheel adapters, 155 4 lug to 5 lug adapters). Improper wheel changing leads to an increase in driving risk. If you would like to install wheels with different sizes, wheel adapters will be your instant and most cost-effective option. Done correctly, your excellent modification will be advantageous. For more details, check on Do You Need Wheel Spacers or Wheel Adapters.
16. How thick 155 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. Currently, BONOSS provides various thickness spacers to meet your needs. For more details, check on How to Measure Wheel Spacers for My Vehicle.
