Mr. Francesco

Rescently i have installed tein flex coilovers on my S, and some days the weather is around 50-60, and others it is 20-30. During the difference in temperature i have noticed that the S performs much differently. When it is colder out, the suspension ride is very bouncy, and not responsive. On other days where it is a descent temperature out, it performs like a dream.

Now sometimes the S will appear lower, and higher depending on the weather also. This isn't much of a drastic change, maybe just 1mm difference here an there. I have noticed this on level ground...ex: my garage floor.

Im just curious to know how much the temperature affects coilovers, and what aspect it affects on them. I know my tein are oil filled, does the weather affect the structure of the oil in them?

I'm betting your noticing the difference between cold tire Vs warm tires. It's also probable the shock oil viscosity increases when the temp drops, which will also contribute to a harsher ride then when warm.

You can see a 1mm difference in ride height?

Mr. Francesco

normally i can get a 2 finger gap when its cold out, but when its warmer out, it sits about 1.5 finger gap.

at first i though they were breaking in, so i tightened everything up, but its still noticable when i really check it out.

It is normal for dampers to have a change in feel depending on temperature. During the winter, my JICs rattle my teeth out in the mornings, but are butter smooth in the summer. The difference in ride height should have more to do with the rubber seals and / or bushings binding up, or variations in the floor. I haven't found a concrete surface yet that gives repeatable "finger gaps". Garage floors are designed to NOT be level. They are designed to drain toward the garage door.

When my new house was built, the tile guy had to do quite a bit of "floating" to get ALL of the rooms level and flat. There could very easily be a few mm from one point to another in every garage.
