**Halon** · 05-12-2009

Not sure about EVO's, but for DSM's ARP makes L19 studs, that's what I bought. The stud itself is made of the same material as the A1's. But the nuts/washers are the same ones used on the standard ARP's, as they claim that the stud is the weak point, not the nuts.

I do believe on the A1's, the nuts and washers are made from the L19 material though. That's the main difference between them as far as I know.

I'm going to rock the ARP L19's once I get around to taking the head off.
