| | Re: 25 pounds unsprung pounds vs. 500 dollars!!??
Are you road racing or drag racing?
The unsprung weight is more critical in the road racing. For drag racing, any weight is important. Also, the 9" has a greater pinion angle which means more frictional loss.
I'd say, that unless you're pushing some BIG power & running slicks, a well built 12-bolt should be fine.
