I'm trying to install my Tanabe Sustec Pro S-OC Type 1 coilovers. This model comes with helper springs. You cannot adjust dampening on these coilovers. The stock upper mount is used so no pillowball mounts. My problem is I dont know how much to tighten the nut that attaches the stock upper mount to the coilover. I can't tighten it to the factory torque settings without fulling compressing the helper spring which doesnt seem right. Any help would be appreciated.

Here is the coilover, the smaller red spring is the helper spring.

Thanks,Kevin

Dont know what to tell you man. On my coilovers, when I swiched top mounts, I just used my impact gun and tighten them down hard, but as you pointed out, I didnt have a second spring. My guess to you is to call/email the manufacturer.

Called Tanabe and turns out its ok for the helper spring to be compressed. Its only purpose really is to keep pressure on the main spring if the car is jacked up. If the car isn't lowered much, the helper spring will give the car a softer ride too. Just a follow up in case someone finds this in a search.
