Lightweight, alloy wheels are actually a performance enhancement to a vehicle.
this is very true, in fact when building a track car this is one of the first changes that are made to a stock car, as it is the easiest thing to do to get perceived horsepower back... Then, you strip the interior. However, reducing rotating mass has a multiplier of 3 over what a static load is.. But then again, an average interior weights about 3-400lbs...
Oh, wait... This isn't the race car forum... Crap... Oh well...... :~)
I got cast drivers in my LFR's because i wanted them, and they weren't that expensive to add... Even though from a material science point of view, there is no difference. The more folds you put in a sheet of metal the more ridged it becomes, and a combination of the thickness of the initial metal used as well as the number of bends/radius/location will determine the final rigidity of the manufactured piece.
Since Axiom uses a relatively thick piece of sheet metal to begin the process with that is a wonderful starting point, then they press the piece which has multiple folds to add rigidity.. Oh, wait... I'm rambling again....
