Had a few people ask about this, so I just wrote this up, and also added it to the first post.

Setting coil seat height
The IMS59-50700 come with a full threaded body, and the coil seat height needs to be set prior to installing the coils onto them. A proper strut coil compressor is required. Regular rental compressors can have teeth that hold the coil which are too thick, they won't work, as you probably won't be able to get the teeth out once the coil is on the strut. We offer the assembly of the front coilovers with new top mounts for an extra charge.

2 base options:
213mm - Base setting, same as OE, for coil seat height. Use this with lifted coil springs to let the coils do the lifting only
226mm - Taller setting, adds 1" of lift to whatever coil springs you're using. Use this setting with a 2" coil to produce 3" of lift, for example.

• Spin both collars down on the strut almost to the bottom. Never use any locktight, it will gum up the threads and it's not necessary once you see the step below.
• Slide the coil seat onto the strut, with the flattest side facing down (notch facing upwards for coil to sit against)
• Using a tape measure, hold the tape against the lip/notch of the coil seat (where the pigtail of the coil will sit) and measure down to center of the lower mounting hole. Raise or lower the top adjuster collar until the coil seat is in the correct position.
• Once the height is set, take both adjuster tools that were supplied. Hold the top adjuster in place, and bring the 2nd adjuster up to the top one, and lock them together. This is the same as "double nutting". This is insurance to keep the top adjuster in position and keep the height where it is.
• If ever you need to adjust the coilover up or down, ALWAYS undo the lower adjuster FIRST, slide it down out of the way, then adjust the upper adjuster to the correct position. If you try to move both adjusters at once, the threads will most likely get damaged and you won't be happy.
• I'll be making a video and posting it up when I get a chance, as it's a pretty simple process, but worth getting a visual for too.
