Literally fitted mine yesterday.. XRA Eurosport 100mm I used the smaller bolt size and the “E” spacers on mine. I do still have the reflector and lower spacer fitted which might change things if you’ve removed those. I realised that the instructions didn’t take account of the recess the bolt fits into on the Roadlok device itself. Take that into account then the E spacers work perfectly. I can only assume that on some Brembo callipers the bolts recess into the calliper slightly? The bolts also torqued up to 45Nms without stripping although I did it carefully. Lock pin seats perfectly on the middle holes using the above. Pic attached..
