I am installing my Ichiba V2 15mm and 20mm spacer for my 19"oem tomorrow. Assuming the shop install it right on the first time, how often should I check and re-torque the spacer? One of the shop people said I should re-torque it every 10,000 miles? Is it necessary?

 

Re-torque it after 50-100 miles and you should never have to do it again. Then just have it checked when you swap out tires or get a rotation (side to side if you have asymmetrical tires)

This is the same procedure we use when installing new wheels/lug nuts at our shop.

Yea....after I get it install tomorrow. They suggest me to go back and recheck.

 

After that, you dont need to go back again.

 

Yup. Same thing I did with mine and all is well.

 

Wut does it mean by Re-torque?

 

When you "re-torque" down the nuts it just means you basically re tighten all the nuts that hold the spacer on.
