The stock front lugs are shorter than the rear lugs. They wouldn’t hurt in either application.

The problem with ET lugs is if your brake rotor is thicker than “stock” or the rotor is not perfectly centered around the lug holes and the ET part of the nut hits the rotor. You torque it down but your really torquing against the rotor. We are talking millimeters of clearance here.

I tried ET on mine and dumped them because of this problem. Been about 10,000 miles with no issues without using the ET nuts.

I will say the lug that is not covered by the nut (in between the spacer and the rotor) will be exposed to the elements so when you remove your spacers (regular service interval).

Inspect that area and make sure it’s not being eaten alive by rust. You may even want to coat this 1/4 inch of open lug with grease or anti-seize as a precaution.
