Great quality. Looks absolutely gorgeous. Easy to fit.
The studs (from the car) stick out a bit when using these spacers.
However I’m using the OE 18” rims for ST-line X which have cutouts in the back.
With 20mm spacers there’s no need to drill or make any adjustments.
With other rims there can be issues and you could have to make some adjustments.
These 20mm fit nicely on the rear wheels of the Focus ST-line X estate MK4.
If you want the wheels to really push then you could go with 25mm as well.
But 20mm will be no issue with fenders when lowering your car.
These are too much for the front wheels though. For which I got the 15mm.
Had to drill the rims using those. Could maybe have gone with 18mm, no more.
Again using lowering springs 18mm could become an issue with fenders.
