Question How much power can the stock rear end on a 95 Z28 A4 handle?

In theory how much power can the rear end take before needing to upgrade to a 12 bolt? I'm talking mainly street driving and no use of slicks.

250 rwhp to ~550rwhp.

It could snap the first time out or last well into the 10s. Have you prayed lately?

Times and numbers in sig. This was on Nitto DRs. Best 60' is 1.69, most are 1.7s-1.8s. The car made 39 runs this year, plus I drive it everyday 40+miles.

how do you like the cc306 with 1.6 rockers ??? I was thinking of switching to a cc306 and keeping my 1.6RR's . What kinda valve springs did you use with this combo ???
thanks , Justin
