How are these better than the ARP studs made specifically for VW turb0-diesels?

x2

they are MORE expensive, and the threads on the top of the stud appear to be MUCH more coarse than the ARP studs?

what makes these better than the ARP/Raceware studs that cost less?

the coarse threads really scare me.. you want FINE threads for increased clamping power..

looks like with those nuts and the spacer they have a larger area for clamping down?

Just a warning to those who might have bought these:

I got hold of a set of these studs for my compound 1.6TD build. The bolts lost their tension after a few test runs at only 20-30psi boost, tried torquing them up again and one broke at 115ft-lbs, less than what the ARPs are spec'd for (125ft-lbs)

Got them out and exchanged one by one for ARP, some of them showed signs of being stretched and close to break. Have since then heard of about 15 engines with these head studs and failures....

ARPs didn't help me, head gasket is blown so I need to take the engine out again...
