rear end question? i was wondering how much power will a stock rear end take in a c5 car. Also going mid to low 10's in a targa top car would i need to cage it or would i be able to stiffen it up enough with a backbone plate? As you can probably tell i dont know much about the cars other than the motors, so really any suggestions on what is good and what is bad about them would be very helpful

Most sanctioning bodies (i.e. NHRA) will require you to cage it up if capable of 10 s. You might as well back half the thing and run 4-link and a decent diff., that stock axle and suspension isn't going to get the job done with the kind of power it takes to run that quick.

In terms of suspension, check out http://www.dynotech-eng.com/
They are an EXCELLENT company, that I have had good dealings with! They make upgraded rearends, and other parts. I would get their differential brace, and their rearend setup. Those would be the most beneficial to keeping the rear in one piece. http://www.dynotech-eng.com/dte_c5_diff_strut.htm
J-Rod is correct the torque tube is also another weak link in these cars.
