Only reason why I didn't care for LS6 springs was the fact that they chewed the ever living christ out of my dampner on my stock chain after 40k.

I never had mine dyno'd, but I kept my shift points at 6200. I doubt that they'd float around 6k anyways.

For the price of 105's or 130's...I don't know why you'd cheap out on LS6's though.

That's just me.
