As you mentioned above, I had cut down Studs before. This was based on the fact that I got fed some bad advice about extended Studs at the time telling me that there was only one that would actually fit in the hub. I fitted them only to find that they were too long to get the nuts tight. I've learnt the hard way that this isn't a good idea but at least I've learnt from my experience. Anyway, I digress. I've since found this is actually not the case and they are being replaced with 51mm ones.
To that end, I did some investigation of my own last night, as I said I would, regarding the actual stud protrusion between the spacer supplied ones and the hub fitted ones. As it turns out, once offered to the hub, there is nowhere near enough thread exposed so that immediately rules out this idea anyway. Like I said, I was brainstorming anyhow.
What DOES look possible though is taking advantage of the recesses in the Blitz and simply using the spacers as designed.
This thread was simply brainstorming. I'm not a structural or mechanical engineer but I know there are people who are. Better to ask advice than plough on and screw it up.
As another piece of information though, more out of interest than anything else, I counted the turns on the Sparco's to find there was 9 1/2 turns on these correct 51mm Studs.
So the plan as it stands is to simply use them as designed. That way I can still used the Sparco's by removing the spacers but still use the Blitz (which also would struggle on the 51mm ones without a spacer by the look of it). If the extended Studs don't fit in the recesses, get some slip on 10mm ones and just have the Blitz set 5mm further in
