Need to update suspension, no Idea what to order

Hi Everyone,
I am a total idiot when it comes to this stuff. Last summer I had my 2006 Cayman S inspected at my local indy shop. I was told that the noise coming from my rear was the struts and mounts needing to be replaced. I am also in need of lowering the car an inch or so due to the 19" spyder wheels that are on it. I have think that coilovers might be the best way to accomplish both goals. I have been looking at the Bilstein PSS9s on ecstuning, however I have no idea what other parts I would need to order as they only come with the coilovers themselves. Any help would be greatly appreciated, the last thing i want is to get everything disassembled and I find out I am missing something

Suspension is slippery slope as you can literally replace everything and it will cost close to the price of your vehicle.
Find out from your mechanic exactly which parts are worn and replace them.

Questions for yourself are whether you intend to track the car, what is your experience level, and how far do you plan to go if you track it.
If you do not intend to track the car, may regular Bilstein (assuming available for your car) with lowering springs probably get you to where you need to be.
for a reference, that set up cost about $1800 installed on my BMW.

Just got delivered some Bilstein B8s and Cayman R springs. Should be 20mm lower. Already have new F+R strut mounts and will order new spring pads & front strut bearings. Will likely install late spring.

We can get you a set of coilovers and the parts needed but it gets a little tricky if you're not sure what is needed or wanted. Lot of people change a lot of components like control arms, bushings, end links, etc.

Planning on doing 3-4 track days this summer, but most of the driving will be on the road. I will most likely be doing the swap myself as I am fairly mechanically savy (I have a daily driven 944 that I do all the maintenece on), however I am fairly new to modding, as my 944 is pretty much stock. I know I need to replace the top mounts as well, but I have no idea which ones I need, or what other additional parts I would need to buy. The shop that did my inspection did not mention that any of the control arms, bushings, etc needed replaced, and from what I can see I believe them to be correct

I'm trying to find out the the stock or factory-option swaybar diameters are for my car. I don't think they are both stock now,

Here's the data on the rear anti roll bars.

EMG- I have had Ohlins on my car for over 5 years without any fluid leakage. I'm using their normal spring rate of 400 lb/in F and 458 lb/in r. The reason I bring up the spring rate is that when lowering your car, you will actually need higher spring rate and the accomping valving to match to keep your car from bottoming out. That's one of the primary function of the springs. Mine is lowered about 34 mm over stock or 14 over PASM. I still have the full amount of suspension travel as Ohlins have a method of changing the ride height without reducing suspension travel and a LN/BRS skid plate. Go to Ohlins setup and see how to install these coilovers. You will have a single golden control **** for both compression and rebound.
I have used my car for many different events including HPDE, Porsche Touring, autocross, bike hauler, and just plain canyon driving. These coilovers are an excellent investment if you keep your car over 3-4 years. You will lose money in a short term sell off though. Now, all the money i put into the suspension over the years is paid off in performance return. I do not expect to get any additional enumeration with all the mod I have installed, rather I use them all.
The lower control arms need to be upgraded when you install any springs or shocks. The rubber bushing are probably shot. If you do change the LCA's, the adjustable camber LCA products will allow you to get more camber than OEM -1.5f and -2.1r. I have found that the Ohlins can control a lot of camber to help keep the tire footprint fully engaged in cornering. No tire roll with over -2.5 f and -2.4 r. Many owners are reluctant to get this type of camber due to the inside tire shoulder wear. I've got a good local speed shop who setup my alignment, which allows for well over 14k miles on tire wear. I do flip my tires though.
The suspension is the key to this car. So with Ohlin's and adjustable LCA's you will have the foundation to grow with your car. Then you can think about long tube headers, wide wheels, wheel spacers, short shifter kits and cables,
