Lowering links all the way mate. I fitted some and it was so easy to do, I've adjusted my ride height in 5 mins as I want to go lower but now I'm at a perfect height..... The links I purchased now have an even better version out that you can adjust whilst on the car.

Depends on how much you're going to adjust and lower mate....
I went for vag genuine Bentley wheels. The off set is pretty low so they don't poke out as much as I wanted so I'm going to run spacers to get the look I want. 20" is more than enough....
21" and lowering will cause issues I think, and there are far better looking wheels in 20"..... Oem high end vag wheels just work so well.
This is it pretty low for a daily driver.
But this is how it was before I dropped it some more like above pic.
