I had the top line FK konigsports in our jetta.

Awesome coilover with damper adjustability, and they go super low unlike some others i researched.

I never had our Jetta super low but for my partners daily driver she loved it and it handled sooooooo much better.

I got ours from ECS but the Aus dollar was a lot better when i got them.

IMO i will never go with a lowering spring ever again....Coilovers all the way.
