ford 9 is 25 pounds heavy,is it worth it in a 425hp street car???

 

Nah- 12 bolt should hold up just fine as long as it is properly built.

 

But what about the fact that you can get an aluminum center section with the 9 inch. I would think that makes it lighter than the 12 bolt.

 

Chevy 12", dang that's a big rear <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> <img border="0" alt="[jester]" title="" src="graemlins/gr_jest.gif" /> !

9" can be made lighter with the aluminum center section and other such lightweight parts, but it gets pretty expensive there. Plus if you don't have TCS, you cannot retain your ABS. 12-bolt should be able to more then handle what you're putting down with the car just fine. It'll also be a little quieter.

Your car is too heavy for an alu center plus drag racing. Ideal weight is max 2800 lbs for alu section.
