Coilovers settings tip - reduce bounciness? - Toyota Yaris Forums

Hi folks,

I got a BC coilovers, which I believe it is the same as Megan, etc.

For the fronts, I increased the height a little bit so that the wheel gaps are even with the rears.

Rears are left untouched, basically installed without adjusting anything.

At first the ride is somewhat bouncy, so I instructed the installer to increase the front springs preload to 5mm. This really helps on reducing the bounciness greatly.

After the coilovers have settled in, I can still feel a slight hint of bounciness, especially on low speeds (start-stop traffic) even on a smooth road. The bounce is subtle, but enough to get me nauseated.

A friend took a ride and he commented that the bounce feels unsettled. I've tried all damper settings (full soft, medium, full hard). The bounce becomes more apparent if I set the damper to be more stiff. At 10 clicks or lower, the bounce is acceptable but I'd like to make it perfect.

Any tips to get the best out of the coilovers? Bumpy is fine. I like a firm ride. I'm very sure the unsettled bounce feeling can be eliminated.

The bounciness is felt on the fronts, but who knows, it may be caused by the rears?

Should I adjust the rear springs preload? or increase the front preload to 10mm (close to 1/2 inch). Any inputs are very much appreciated!
