My Dad has an A6 2.7t and the stock suspension. The ride and height is bothering him as he has 17" BBS RK's and wants a lower ride height and a ride feel more like my A4 on Eibach's. Firmer and less body roll through corners. I am what the springs of choice are for the A6. I was looking at the Eibachs at $280 for him with no shock upgrade. Sugestions would be most appreciated. I was looking at coil-overs for him but I think that the ride might be too extreme for him compared to a spring upgrade, actually to extreme for mom riding shotgun!! I have never run a coil-over suspension so please tell me if I am wrong.
