How do I measure for adapters?

[MrQuick]

Hey Matt,

well the adapter/spacer is going to take or make up the space you need to obtain the proper back spacing. I like to mount up the rims with tires mounted and use cheap spacers stacked so I can temporarily drive the car in our parking lot then check for clearance. Go into drivways,go over bumps and such. Then I measure the spacers used then order. My source custom machines the adapters to the specs I send them.

Depending on the car you own there should be a known back spacing distance.

Measure the back space you have on the rims you want to use.

Now subtract the known good number from the actual rim back space and this will give you the desired adapter/spacer size.



Remember to measure your hub circumfrence and the rim hub opening to get the proper hub fitment.
