I'm about to start collecting parts for my 6-speed conversion. I'm planning to buy one of the kits from Advanced Automotion, and I'm trying to decide which axles to get.

There appear to be 3 options:

Standard axles - I assume are stock for 6-speed A6
Upgraded TDI axles - stronger for TDI applications (+$375)
Heavy duty axles - strongest with larger inner tripod joint and larger tube (+$695)

What are you 6-speed swap folks using? Has anyone broke an axle on these cars?

The car will be a driver, not a track car, but I will certainly hit the track occasionally (drag and open track) and would ultimately like to go as far as upgraded turbo's for power.

I also realize the price difference is not huge relative to the total amount I'm going to spend, but my budget is not unlimited, and I want to spend money on things that truly add value, not just upgrade for the sake of upgrading.

Thanks!
