IMO, I don't think you need to add a metal bar. Your front bumper should absorb the impact. I hit a good sized German Shepherd going 70 mph when I had my '87 4Runner, and it only damaged the lower valance.

How about a price on your '98 V-6 2WD springs? I'm located in Los Angeles, and I'm interested in lowering my 2k Ltd 4x4.
