I've copied this from another thread I posted in. Hope it helps. Any questions feel free to ask

I have Fk streets on my Jetta. You can almost lay frame with how low they go and still ride surprisingly well. I've had then just over a year and they're still as good as they were when I got then new. I'd highly recommend them just make sure you protect the threads to stop then seizing. I personally wrap the threads in electrical tape then put a small tie wrap around the ending of the tape to stop it peeling off over time. The only bad thing is the droplinks. Mine only lasted 6 months before the rubber split on them and seized up.
Few photos -
I have 10 threads left up front with no helper springs and in all the way down on the back with the adjusters still in place (pictures of coil overs were taken when I was riding slightly higher)
