beyond all the scientific data thats been thrown out the bottom line is with 10mm arp AND raceware studs they lifted after all the proper procedures were followed and the 12mm studs sold by srm and evoms havent. retorque them if you want yet both shops dont and they still havent failed with over 1100 awhp and up to 1700 hp on a 997. thats what someone like me needs to know. what works and what doesnt.

 

^^ and we can all hope that the ARP studs that have been found work equally well! We should know soon enough as there are a few motors going together with them to find out

Anyone know what material they're made from? Original application was for a diesel motor so I suspect they will hold up very well.

 

Ok, I am getting the 12mm ARP's. My cases are at Silly Rabbit getting drilled/tapped and I should be building in about a month.

 

Pretty awesome.
