So it came time to update my worn suspension at 192k. I purchased the Uro Control arm kit from ecs tuning along with the s4 koni yellows and a4 h&r sport springs. This was my first time installing suspension so my experience is limited. The front control arms were horrible pain in the asses to remove. The lower control arm bolts dont have enough room to come out easily and the ball joints can take a while too, had to use an acetalyne torch on them and the pinch bolt for the upper control arms. But anyway here in my initial impression. I ******* love it. I had read that the sport springs are bouncy from other forums but i compensated by increasing my rebound adjustment on the Koni yellows. Fronts are set at 50% stiff and rears are at 30% stiffness. First day out and I noticed handling characteristics that my stock suspension was no where near. Obviously its a stiffer ride but its still very comfortable considering. Body roll is very reduced and ill be upgrading to the 034 rear sway bar and subframe brackets for added oversteer. The drop on these springs are perfect, not too much and not too little. Definitely gave me a more aggressive stance. But thats about it for my review but Ill feel free to answer any questions about the setup
