 Unfortunately, it is just the opposite, they will reduce reliability of the
 engine. Anytime extra weight is added to the valve stem end of the rocker
 arm such as a roller tip, it requires more spring tension to return the
 valve train to the closed position. Add more rocker arm ratio and it takes
 even more. When rocker arms are properly designed to not wipe against the
 valve stem (such as ours are) there is never a need for a roller tip."

The point of the Pauter roller tips is that the whole weight of the rocker
arm has been reduced SO the overall weight of the arm is much less than the
steel arms even with the roller tip.  Plus they are talking about RACING
engines TURNING 7000, 8000, 9000 RPMs, the WBX engine is limited to 5600 RPMs.
