That's a good price...I paid $560 last spring for mine, and that was the cheapest I could find them. I installed mine, but that install price is good.
As for your original question... On my '99, with the shocks set to full soft, it is still just a bit stiffer than it was with my stock shocks. But it was a small enough difference that my wife didn't notice until I pointed it out. But even at full soft, the ride is much better dampened with the Konis vs stock shocks.
