another story on my buddys 08 6.0 ly6 with a 228 cam broke the 918s just idling in park(very lucky) he went with the Lunati duals
Weird - haven't heard of any of them breaking.
Those are PAC's.
I was referring to Comp's. A lot of the big HP cars are running Comp 921's. They're making big, big numbers and the springs are lasting over 40k miles. It's recommend that's when you change them out though.
i have PAC springs and love them
01 Silverado
Sorry to hear about the phantom issue, Blacklist. What are the specs on that cam btw? Get that blower cam in there soon so you can lighten up the stress on those springs. You don't wanna get embarrassed by a Bimmer
