You're probably saving about 10 pounds (disclaimer, number pulled straight out of ass). If you have a steel one sitting around you can weigh it and the aluminum one is gonna be about 1/3-1/2 the weight (if they were identical it'd be closer to 1/3, pretty sure they're not).
I've never had any problems with the aluminum one on my car, but fatigue for aluminum is different than that of steel, and it's important to be aware of that. Andy, There had to have been something else wrong with that bar. I may have to put my car on the lift sometime this week and check that out. |
