i have a 1996 z28 with CAI,catback,under drive pulleys. I am in the process installing a 2600 vig stall with shift kit and trans cooler and 3:73 with drag radials, everybody on ls1tech tells me that i will blow my rear, its a 10 bolt 7 1/2 and those are the week ones, so i have a option, buy a 12 bolt that about 2,000 or would i be safe without doing the 3:73 and just the stall ect with out killing my rear
thanks
thanks
I have a stock 10 bolt that I have hundreds of 1/4 mile passes on with the last 75 or so being on ET Streets. The auto is definatly easier on the rear than a M6 car is. You can find used 12 bolts for around $1500, sometimes even less even though thats rare. I think you will be fine with the stock rear for now until you start making a lil more power.

You may want to think about another carrier too. I had an Eaton carrier in my ten bolt and it held up to a lot of 12.4x runs at the track. I now have a 9", but my 10 bolt still worked when I took it out!
Really, your only options are going to be a stronger carrier, a 12 bolt or a narrowed Ford 9 inch. The power is not going to kill the rear its the sudden jerk during your launch if you hook really well.
