spyntec shorty

Does anyone know how much the spyntec shorty free spin hubs stick out past the stock center caps? Also some true mpg gains with lock out hubs i hear anywhere from 0 to 3 mpg gain. thanks.

Legnth is about 1. 75" less than old hubs- - - that should put the stick-out about 1/4". On my 06 Mega I've picked up 2. 3 miles per gallon both loaded and empty - - we are full timers and pull a 27' bumper pull RV. I don't race from traffic ligh to traffic light. If I pay attention to my speed, and try to keep it at 70mph. Just turned 50K on my SpnTechs with out a problem.
