The H&R 20mm spacers install with low head bolts supplied with the kit too, the OEM wheel bolt secure the wheels. To all who install this H&R 20mm spacer kit....the wheel bolts must be cut/ground down by at least 1/16" on the thread end so they actually secure the wheel. If you fail to do this, the bolt will bottom out against the hub and not secure the wheel.
