Have an 06 non s line 4.2 A6 that I would like to add h and r springs too. Can the stock shocks and struts handle the setup? It only lowers by about 1.6 inch. Any advice would be appreciated.

 

They should be able to handle them for a little while, but with the 4.2L in there, and the heavier A6 chassis, you are probably best off going with new shocks also. Are there any good coilover setups for the A6? I am not too familiar.
