I am assuming some of you have swapped to this system. My car currently rides great (99 STS) but large bumps at 75 the back end seems to hop to the right. From my limited reading here it sounds like i may have tired shock/strut system. Well the new ones (factory)would actually cost more then I paid for this car (maybe the reason i got it so cheap).

Is the ride close to the original? Since it was an Air system before, I am assuming the replacement ones have some way to keep the compressor from running, to fool it? I have read they have some resistor or plug in.
In the actual install do the replacement once have a place to plug the old caddy stuff in? Is it basicly a swap, just unbolt and bolt back in and hook up whatever was hokked to old shocks ot hte new ones?

Could somebody who has installed some (themsleves) give me some feedback on how hard, and if all hookups where taken into account.

thanks!

Well if you replace the back ones from originals to Arnott, you will still need the compressor to fill them up, because they have a fitting where the air lines go into, as far as the resistor yes they send you a resistor that just fools the computer to think that you have original shocks, but you have to ensure is tie up in the suspension.

They are not hard to install, it took me about 2 hours to do the rear ones and another 2 to do the front ones, just becareful with the front ones though because you need to pay attention to where the old is compared to the adjustment or else you will need to have the car realign, which is good to have done anyways but it sounds really crappy if you don't try to have as align as possible, it sounds like if the tires were rubbing on something.
