A friend with a 94 F250 wants to put custom rotors on . His are warped and he wants something better . Anybody know anything about custom ones or where to get them ? THanks

Tell your friend to check out F-150online.com I'm sure someone there or one of their links will point him in the right direction.

When I had my Yukon, a lot of the guys on that message board swore by Praise Dynobrake cryo-treated rotors.

Never tried them myself, but I've never heard anything but good stuff about them. Thinking about trying a set on my Excursion.

If the truck is diesel(more important if auto),get an exhaust brake.
