Well, despite what I said before, I couldn't resist ordering up a set as well. Sam's probably right, but I figured it couldn't hurt to give them a try with the stock rear bar. Check the classifieds section around June if you miss this GP.

Sam's point on the G2 fronts was simply that if you want to experiment with different spring rates, coilovers make more sense in the long run than ANY fixed rate lowering spring. He never said the G2 fronts won't work.
Odds are VERY good that Sam is right about the rear springs for autocross
My point was that since the rear springs come with the set, you might as well try them at a test-and-tune (no points at stake) and see how you like them. If you want to hit an open track event every now and then and don't want to swap springs, or pull a tire trailer, they might prove to be an acceptable compromise for autocross even if they aren't optimum.
IF they [the rears] ARE too stiff for autocross, I certainly wouldn't pull the whole set off and sell them in 6 months (though you probably could with little loss). I'd switch the rears to something more suitable, and keep the G2 rears on the shelf. You never know when you might want to swap them in (for a track day or whatever). I certainly wouldn't sell off the just the rears either - keep the set together (for later resale value if nothing else).
In other words, the fronts are a fairly safe bet for autocross and a lot of work to change. I wouldn't ditch them just to change the rears.
I AM an engineer with all the personality flaws that normally implies, so this next point may not apply to everybody. Since the G2 rears are part of the set anyway, and rear springs are easy to change, there may be some value to trying them just to learn sumthin'
