most people on here blame the diff when it has almost nothing to do with it.the diff plays a role it wheel hop but is not even close to the main cause.

You may not be getting hop on the street right now but the minute you try and launch that car on a prepped track I promise you that you will be amazed how bad it is. Mine would hop so bad at the track that the Service Stability System light would come on and the warning screen would pop up on the NAV.

Agree 100% with both of you

So for yourself I would reccomend going with a solid cradle mount and dont mess with the bushings like was said earlier.

As for the 8.8 or 9", for me its money. There is a 2k price difference between the two, and I have seen no one break either in a V. Or break either anywhere that I have found yet. I know plenty of drag racers have done it (broke both kinds) but they did not post pictures or write stories about it online.

So basically what I'm trying to say is a 4000lbs car+1000hp+drag launch at 4k rpm or more=big $. Repeated beatings, somethign always breaks.

Also, after you beef up the rear, the cluitch is the next weakest point, then let says you put in a 1000 rxt twin disk then the trans will be the 1st to pop. and so the story goes on. Build it all up, spend a but load of money, and expect it to last forever while beating on it? Good luck!
