I'll try and remember to weigh the D2 subframe before I put it back on. I doubt there will be a significant enough difference in weight to the D3 unit to justify the work.
The C5 R/S6 had aluminium subframes whereas the A6 had steel, but the fronts at least weigh exactly the same. I believe Audi used aluminum for the R/S versions simply because it was cheaper to make a small quantity that way, rather than tooling up to make steel ones. Potentially its also stiffer, but the amount of rubber they put in the suspension would negate that anyway.
By the way, I have finished for xmas now (yes, how very dare I?  ). Back on it on the 27th when the fuel tank comes off in preparation for welding up the crack on the 28th. |
half way down page 10. steel subframe is 30kg and aluminium one is 20, they had to modify some bracket and bushes too, too much work.
enjoy your time off!
