I ordered a set of these from speed factor and had them installed recently.

this is what they look like and the boxes they come in although this picture is not mine.


there are 3 valving options when you order them.
-street comfort
-street sport
-track race

Each one comes with certain spring rates by default.
I believe the first 2 have the same spring rates and track race with a stiffer spring rate.
There is also the option of having custom spring rates and custom valving at no extra charge or if you want swift springs you can pay extra for that too.

I chose the street comfort valving with their default spring rates for the 98 lexus gs300
spring rates are 14k front and 10k rear for my application

they are not preloaded out of the box so I got the shop to set preload at 5mm before installing.

there are 32 damper settings. I have it in the middle at 16 right now and it is a nice comfortable ride like I wanted.
I have no complaints right now.
I will probably adjust 8 clicks softer and 8 clicks harder to see how each setting feels after an alignment this week.

will update with results

    Did you install them yourself?
    Will these see our harsh winter?

        I did not install them myself. They were installed along with a bunch of other things I had done on my suspension at a shop.
        These will be seeing winter and are covered in a layer of marine grease which is water resistant.
        They will be checked, cleaned off and covered in a thicker layer of marine grease before winter.

          I went 1/2" higher than my previous setup so I will take current pic of height tomorrow after my alignment.
          the website says they can be set at stock height or drop 3 inches or more depending on the vehicle but I don't know how much mine can drop.
