I bought a set of drilled and slotted Powerstop rotors from Summit Racing for the rear of my 2001 E250, (Dana 60, 8 on 6.5in lug pattern) but they rusted out within a couple months. Summit refused to provide any relief, saying they only warranted against rust for 30 days. When I called Powerstop directly, they admitted there was a problem with the metallurgy in some Chinese sourced rotor blanks. They offered to immediately send a replacement set, but I didn't want another set of the same model as they too could have been defective, so they offered a different type of rotor that was coated to prevent rust, but that weren't slotted or drilled. The problem was, they were sourced from Germany and wouldn't be in stock for a couple months, so I had to buy a set of stock rotors from my local auto parts store. Two months later, the replacement set showed up, but I doubt I'll ever wear out the set on the van now. So, these are AR8578EVC coated rotors, (the least expensive I found were $75 ea) and come with a set of Z36Extreme / severe duty truck and tow brake pads. ($50 a set a Summit) Follow the link below for application info. I'm open to any reasonable offer, but the rotors are hell of heavy, so I prefer not to ship. Pick up would be in Northern Washington, but I may be able to meet somewhere as I'm on the road a lot.
