Well I've had spacers on all my VWs (8 cars and 15 years) with only 1 issue in all that time - a rear spacer fractured its hub centric ring but that was down to the brand of spacer used (FK automotive crap) rather than a fault with spacers in general,
Some people would say they increase wheel bearing loading and whilst that is true when taken to extremes, but when using 10/12/15mm spacers i don't see any issues - after all running aftermarket wheels such as BBS CH-r in 8.5 et47 is just like running the austins 7.5 et51 with a 16mm spacer
I used spacers on thousands of road miles and loads of track days including the Ring without any issues, it'll be reet
