If you are looking for longer REAR wheel studs these work.
Dorman 610-416
They have a 14.86mm knurl (OEM 14.94mm) and are 52.2mm long (OEM are 41mm long) but the last 3mm are not threaded.
You get a genuine 8mm more threads or enough for varied width of spacers. Around $2 CDN each so cheaper than ARP and easily stocked.
They went in very tight and the rotor does need a slight tap to seat.

 

I'm trying the 610-323 in the front that have 0.129mm less knurl diameter but are 12mm longer. Won't be installing those for a few weeks.
