My story with H&R springs and DRC shocks

[Audi-RS6]

I decided to lower my car

Did factory recall on shocks.
Bought set of springs H&Rs Sport setup.

H&R developed their RS6 setup with old shocks, new ones as you know sit higher, tons of claims including two of our cars.

I installed H&R on stock DRC set up. Nice ride but rear looks ugly. Way too high. I could not understand why they had to make it 1.5 drop at a front and 1.0 rear when all prior a6 setups are 1.7/1.5 and 1.9/1.5

So, question was
1. will the 4.2 set up fit.
2. to figure the difference in weight between 4.2 a6 and RS6
3. Should it be Sport or Race setup they have for 4.2

RS6 vs 4.2 door stickers shows same front weight and 60lbs heavier in rear. Possibly because of battery and additional cooler.

So I bought H&R Race setup for A6 4.2 quattro. And got what I wanted. More stable and better looking ride.
