Mine is a 2005 with just under 79,000 miles. I don't know about any previous suspension work, as I've only had it for about six months and wasn't privy to prior service records when I bought it.

I ended up swapping out the factory front struts with Arnotts today. From the online research and calls I made, there is apparently not a single coil suspension kit that works on a 4.8is. Even KW told me that their coilover kit is not compatible.

The car obviously feels much better with the new Arnotts. I had slow leaks on both sides, which generally meant that car was having to pump itself up every time it sat for 8 hours or so. Steering is much more responsive and the ride feels both more stable and softer at the same time. Not surprising, I suppose, considering I was basically driving it around with both fronts at various stages of low to full inflation.

While I would rather have just put coils in and forgotten about the whole air system, the Arnotts weren't too bad. Once I get my core deposits back, and with the decent labor rates at my indy, the total damage will be a tad over $1300. I would have tried tackling the install myself in the driveway, but I've got too many other things going on right now.
