Wheel Spacers

What's the cons of adding any wheel spacers?

 

Can't use impact wrench.
Should use torque wrench.
Might wear the wheel bearings faster if you go big.
I run 1" Bora spacers on TRD sport 17" wheels.

 

Not trying to go big on tires. Just wanting to do a level lift with spidertrax wheel spacers. Maybe 1.25".

 

I've got a set of 1.5" for sale, price is OBO, if you're interested:

From a physics perspective, more wear on a lot of your parts.

 

I think you really mean wheel adapters which are used as wheel spacers. You will likely need longer wheel studs if you go over an inch wide with adapters. Max you should go with spacers are quarter inch (although link below says 5/16ths).
