got some one who is going to sell me his eibach springs never used still in box. he said $125 for the set. sounds like a good deal. do i need anything else for my suspension. how much will this lower the car i already have sport package and i swear my car is lower than every other audi i see. is it possible these will make it too low. i don't want to grind on speed bumps or curbs.

 

wow....do a search.

you will need shocks.
will lower around an inch to an inch n a half or even less seeing you already have sport suspension.
grinding on curbs, WTF? if your hoppin curbs you will need a lift not a lower.
speed bumps vary. you will learn what you can and cant do within the first week. i am way low and most speed bumps are fine if i take them slow or really fast, LOL..
you will however rub on the fenders so they will neeed to be rolled.
