Does anyone know if there are any real steel, rather than aluminum, skid plates available for a 2013 Gen 4 Outback? Primitive appears to make some nice products, but steel would be much better and is what is generally used on a 4WD vehicle. Recently did 3 intense days of offroad in a Tacoma over many rocks in Death Valley. Am interested in putting skid plates on my 2013 CVT, but would prefer that they were steel. Weight difference should be insignificant.
