the pans and VCs are just aluminum. alot of buyers have ran our pans and have noticed nice drops in oil temp using aluminum. and on some wet sump pans we use the extruded fin looking stuff. like the cooling fins on a computer, we use that on some wet sump pans to dissipate heat and it seems to work well. you can see it in some of the pics on the website.
we make fox chassis pans for a mustang. with the front sump and all.
