Default Improving ride comfort with coilovers (or maybe other)?

I've got Tein Street Flex Z coilovers on and am considering new setups, but for the mean time want to know how to improve ride comfort. 2013 STi hatch. any suggestions welcome.

Have the shocks revalved by someone good. Not just any suspension store.

If the car is very low raising the ride height could help.

Also make sure that they are working in the right range of travel. Ideally you want as least as much droop (downward travel) as bump. If the shock itself is limited on travel (like tein tends to be) and the springs are not the right rates that can be hard to accomplish and the shocks will bottom and or top out. Which is bad for ride comfort, and handling.

You can check this easily enough with zip ties- put one on the shock shaft and lower the car and see where it ends up. If it's not near the middle of the range you can adjust the preload on the springs.

Since most street coilovers are build for lowering, have much higher spring rates that are usually linear, and not necessarily high quality dampers to control them, you're almost guaranteed a harsh ride.

You can check to make sure you're not always on the bumpstops as the previous post said. Some coilovers have more travel then others, and some can be adjusted independently of ride height.

You could look at custom revalving for your coilovers, and possibly changing to softer and progressive coilover springs (most are linear, though). All that can add up of course.


For a street car with no to minimal lowering, I've always found Koni Sports to be the best for a smooth ride, especially when paired with moderate rate progressive springs like RCE Black/Yellow. Again, too much drop and you'll be on the bumpstops all day, which is bad.
I had Konis with STI RCE Blacks (320/320lb rates) on my WRX and it was perfect.. way smoother on the road than the OEM suspension, and handled amazing on the track with the stiffness turned up a little.
