If you have a a4 then a 12 bolt will do because you can preload the rear, for a stick that will see 6k clutch drop launches you will need a 9" to take the shock !

Weight was the concern here, and seeing guys pushing 1000whp+ on a similar rear end.. I'm sold..

Not sure what the lightweight 12 bolts weigh though

you are saying that the center section of a 9" is lighter than a complete 12 bolt?
I can believe that, you just have to add the housing which is massive... unless you do a Fab 9.. which increase price at least 1K..
I think that if you have money to spare and want something bulletproof, a Fabbed 9 inch with lightweight center is the route...
But me as a budget racer, a Spooled 12 bolt will do the job (big hope)

Tell your friend that he made a VERY wise decision.. I've had both (12 & 9) and I loved them both. But, the 12bolts are noisy as hell and tend to whine no matter what you do and they aren't even close to bulletproof.
Now I have a narrowed 9in, 35 spline gun drilled axles, lightened spool and pro gears with an Aluminum center section. I think its pretty safe to say that its bulletproof or damn close to it...

for a top of the line, bad *** 9" it's around $2600 if you get all the options and a decent deal. maybe a little more. i would assume it's quite a bit less for a 12 bolt, maybe $1800ish or a little more.

Your an A4 so a lightened 12bolt would be perfrect for you. Hell Jeremy is running a 10bolt and hitting 1.6 60's with his and has done 3 gear changes in the last 2 or 3 years.
