Looking to buy a set of springs, and I have a few questions.

1) What options are out there? I know H&R and Eibach are two of the options.

2) Which springs are supposed to be the softest and as stock feeling as possible?

3) Does anybody know what the spring rate of OEM springs are?

4) Since every car is different, how does the A6 feel when its dropped? Do all springs make the car ride harsh? Or are some much softer and better than others?

I ask because I live in NYC, our roads can be poor.

This is for a 2005

 

In general, you want your spring rate to be equal to one third of your corner weight. So, for example, if your corner weights are 1200 each side front and 900 each side rear, you would want (assuming a linear spring rate), you would want 400 pound/in springs in the front and 300 pound/in springs in the rear.

I believe the A6 springs are progressive, meaning they start out with a low spring rate then get stiffer as the coils get compressed. This helps the ride quality so if you can find a good, aftermarket progressive rate spring set, that would probably be your best bet for retaining the stock ride quality and getting the enhanced looks of a lowered car. Also, consider larger wheels and tires as some of the best lookiing A6s I have seen have just been larger wheels and tires.

Good info!

Now, from experience or research, can anyone tell me which springs are softer on an A6? H&Rs or Eibachs?
