I have an 02 A4 with the Sports Package. I hear I can purchase Bilstein Groove shocks and drop the front of my car about 0.5" to match the look of the rear?

What are these "Groove" shocks?
Where's the best place to buy these?
Is it necessary to do the front and back, or can I just do the front?

Thanks!

 

Perhaps you are talking about threaded body shocks?

 

Beats me... AWETuning has this as an option I believe. Since I don't know much about this, I can only assume that has everything to do with the adjustability when mounting?
