Choose the Right Size
The thickness of a spacer is a deciding factor that influences its utility. Neither too thin nor too thick spacers work well for your vehicle. A thin spacer does not solve the problem of wheel-caliper interference. If you are looking at spacer to solve the issue of the wheel rubbing against the brakes, a thin caliper does not address the issue. With a thick spacer, the wheels hit the fenders but do solve the problem of brakes. You need to be very particular about the width of the spacer if you want it to perform optimally. As minimal a difference in measurement as a quarter of an inch can affect the function of the spacer adversely.
Testing Many Spacers
Instead of going through the long process of testing many spacers on your wheel to arrive at the right one, there are some methods you can use to get the correct measurement. The testing of different spacers can cost you a lot, as once you test a spacer on your wheel, you cannot return it. A more cost-effective way is to measure the thickness by using some simple techniques.
The Cost-Effective Method
To ascertain the gap between the wheel and the brakes and suspension you require nothing but a few washers. These are not any particular type like the split washers or the plastic ones. Get the ones that are easily available at the hardware store. Ensure that the hole in the washers has a diameter that is sufficient to pass through the wheel studs. You may need many these washers, so get a box of these from the local hardware store.
Fit the Wheel to Test Space
If your wheel has nuts, use the same number of washers on each stud. Place one or two washers on each stud and then try to fit the wheel. Watch out for the clearance between the wheel and the caliper. Do not rotate the wheel, as this may cause damage to the new parts. In case, you require more clearance keep adding more washers one at a time, till you reach the desired gap.
Clearance Necessary for the Brakes
If you are placing the spacers to solve the issue with the brakes, experts suggest a difference of one to three mm is enough. Do not add too many washers in your enthusiasm to achieve a wider gap. This may push the wheel closer to the fender and create another problem for your vehicle.
