Hey guys. I am currently getting my car setup for my first autocross event and was going through my suspension today. I had to raise the car up slightly :down: seeing as I had very little wheel travel and rubbed under daily driving conditions so I know it would suck to auto-X. Anyways as I was going through I noticed that the nut on the top of the front pillow balls seems like it is only on with like two or three threads. The nut is tight but I was wondering if anyone knew a specific torque setting for this particular nut. By the way these are s14 kei-office type xr coilovers. Any help is much appreciated. Thanx, Cameron

i'm not sure about actual torque specs, but you should be fine, just tighten them as much as you can by hand

i think the 14mm bolts are 85-90lbs and the smaller one on the top are like 30 or 35.

Here's what you gotta do. Don't try torquing to 90ftlbs.

1. Loosen all preload from the spring until there's at least 1.5" of space between the top of the spring and the upper spring perch. There should be zero pressure on the spring whatsoever.

2. From here, you'll be able to tighten the piston to pillowball mounting bolt until it stops, by hand, unless the threads are corroded. To insure it's snug use a ratchet and a drop or two of lock-tite for peace of mind.

3. Retighten the springs' lower collars and add at least .5" or more of preload. How do you measure preload compression?

Once the spring is butted up against the upper perch, tighten the lower collar until it touches the spring then stop. There should be zero play/pressure between the spring and the upper and lower perches. You should be able to rotate the spring freely and the spring shouldn't jiggle up/down.

Mark with a sharpie or visually remember where the lower collar resides then tighten and compress the spring until the lower collar moves up the threaded body at least .5". The more preload you add the more effort you'll exert with the spanners. Of course, don't forget to tighten the locking collar.

I'm running about 1.5"+ of preload with the same rate springs. The preload of the spring will apply pressure to the mounting bolt. That's why, currently, it seems like your bolts are tight enough.

Hope this helps!

I have stance coilovers. I emailed them the other day cause ive been having as of yet, unresolved issues with them. But one thing they told me is to torque the top nut (the pillowball one your talking about) to 55 lbs.

I dunno how different it would be with your kei office coilovers, but at least thats a start.

Hey thanx a lot guys. I will have to pull the preload outta the spring tomorrow and then see if the bolt still feels tight. Thanx again for the help. Cameron

Ya, I have been wondering about that nut on the top of my stances also. I went and looked at all the threads about them and all the pics on there website, they all appear that way. We tried to tighten them a bit but didnt really do much.
