To ARP or not to ARP

H13 costed me 695 shipped. Hoping for some good results with them. Will be doing ns300l inserts on the corners
Well there's more threads on the pro series and if you combine them with a ns300l insert with the first half in of threads not modified like they come for arp 2000 kits. You will forsure be able to have a better clamp on the cylinder head. My h13s arrived yesterday will compare all 3 of them for you guys
Yes, and from my observations id say yes. For the reason that the stud is shouldered in the proper spot. The pro series shoulder should start alot sooner . The pro series have another inch of threads that don't engage anywhere. Which would make it a little weaker compared to the shouldered stud. Pro series do have an advertised tensile strength of 270,000 though. Not sure about the H13s. I heard there a bit stronger than the arp 2000s but not quite to the strength of the arp 625s. I could be wrong on that please don't quote me lol
The full 11mm H13 were 695 shipped. The standard kit pro series were 788 shipped from Germany. The arp 2000s from race engineering were 310 shipped
Tell me about it. Hoping for n54 specific kits to come down in price a bit. But with demand so high for good studs I don't see companies lowering the prices soon
I mean how hard is this to make. For $700 I could get a machine shop with chops to make those out of ... any material I want. No one is jobbing this stuff out of Taiwan, where top quality stuff can be easily sourced? Is it a reputation issue?
Yep. It is a cash cow.
And i guess it is a reputation thing. I mean which studs do you know other than ARP? Here ppl know shit about studs but just repeat what they heard "ARP is the best" ... but why? "I don´t know. Everybody uses them". That´s it.
Yeah there has to be another bolt manufacturer that would make you the right spec stud. For not nearly a thousand dollars
