ACR Shock Upgrade Pre-2000 or post-2000???

[99 Sidewinder]

Which ACR shocks perform better? The Pre 2000 series or the post 2000 series?

I have a 99 RT/10 and I am planning on purchasing the ACR suspension package.

Any feedback would be greatly appreciated.

If you're stuck on stock, it's the Koni 2812s, hands down.
