I would have thought that something else would break first before that part!

Can anyone give a list of all parts that should be replaced to avoid wheel hop? I have an A4 with a 3.42 rear end and soon a high stall converter. The stress on the drivetrain is a worry to me.
Shocks, springs, bushings... what else?

My Coupe has an A4, 3:42's, 2800 stall, 421 rwhp. IMHO the best thing I did to reduce wheel hop was adding Pfadt coilovers (i.e. losing the leaf springs). It also stopped the inherent rear-end swing out to the right when breaking the tires loose.

You have to pay attention to the car and shut it down when you get wheel hop though. It is difficult to completely abolish wheel hop so it is important to know the signs and back off.

That is my configuration and with drag radials and a fair number of passes down the 1/4 mile nothing has broken. I have the hardened output shaft and that is it.

I recently put my Z back together after shattering my stock diff. I added an ECS trans brace, and a Pfadt diff mount/brace, and per instructions, removed the factory dampner. I can't definatively say my wheelhop is gone, because I'm still driving it pretty easy. I have broken the tires loose for about 100 feet or so, and rather than still needing to counter-steer to the right to stay straight, there was no hop/shudder that I could feel. That was at about a 50 roll. I've never gone hard from a dig, (on this car) because it'd just spin anyway, and tires are expensive.
