The DBA warranty excludes a rotor which has "been subjected to conditions beyond those for which it was intended, such as, but not limited to, being used in any form of motor sport." Given that the 4x4 Survival Rotors are advertised as being designed for "serious off road and heavy towing" that would imply that off road use would not automatically invalidate the warranty.
In fact the current DBA catalogue claims:
Quote:
4WD vehicles often suffer significant brake fade and reduced performance when it comes to heavy towing, big downhill sections and disc cracking / shudder due to rapid heat changes during water crossings. DBA solves these safety and performance issues with the Survival Series T2 & 4000 series T3 rotors for extreme 4-wheel driving and / or towing.
