Sorry if I am repeating (for someone) the post, since I posted on other foruns, but I am looking for help/advice on this...
Today I was changing the front disks and for my horror, as I suspected, on my new disks the HAT was diferent, from original - offset 5mm smaler then original.



(got it fromo PHG Automotive on eBay as for Audi RS2 322mm)
I was about to change the HATs. The original hat can be unbolt easly, but I stop on doing it before confirm some issues:
- does someone made this kind of procedure?
- Any idea of torque values, how much do I tight those small bolts
on hat? they unbolt easly on old one...
(already someone told me just to tight them like tighting the weels)
- do I need to calibrate the disk?
...or will be better to try to sell the disks? and get from audi.

thanx
