Not yet, but they'll be coming soon. From what I've read the 1.8s are okay on stock springs if I'm shifting under 6000 rpm. AFAIK I am shifting under 6k...Actually I haven't done a WOT run since the tune, so I'm not sure. You'd know, lol. I guess it also shows how much I drive the car hard.
Nice thing about all this is I don't have drain coolant\take the alternator bracket off. The 99 Camaro bracket doesn't hang over the valve cover at all so I have to take the alternator off, but that's it. That's why I don't care about tearing into it twice, the valve cover gaskets are under warranty also, so it'll be free to do (minus the cost of the springs and such of course).
