Project EJ Honda Civic – Skunk2 Pro-C Coilovers


The upper mounts on the Pro-C are cut from forged aluminum blanks.  This gives them much better strength.

Although the Skunk2 Pro-C’s have a lot of features that make them attractive to us, the main reason we went with this set is the fact that it provided us with easily accessible, single way 12 position adjustable valving, as well as up to 3 inch variances in ride height without having to worry about hitting the bump stops. Like I mentioned before, this is my daily driver. Finding a balance between having a fun track car and a comfortable daily driver isn’t an easy thing to do. Fortunately though, we didn’t have to sacrifice too much ride comfort for my my daily driving with the Pro-C’s because of its many available adjustment settings. Even with its stiffer settings, the comfort level for daily driving is surprisingly smooth for a track-friendly car.


The top mounts also use urethane bushings instead of monoballs which is typical for performance coilovers.  Urethane is much stiffer than the stock squishy rubber which gives more positive damping control.  Most importantly, it is quiet for daily driving, something I like!  The damping adjusters are easily accessible from the top.  This really helps speed the tuning process.

Speaking of the many available adjustment settings, one of the most advantageous aspects of adjustable shocks is the ability to dial in the settings to the feel and chassis balance that the driver is looking for. The damping adjustment settings mainly affects the low speed rebound damping with a slight effect on the compression damping, which is important for cornering as most body motion like roll, yaw and pitch is in this range.

The adjusting mechanism works with a top mounted knob attached to a shaft that runs through a hole in the middle of the shock shaft.  This shaft is threaded at the bottom so turning it can increase or decrease the preload on a spring loaded needle valve in a passage that allows fluid to bypass the pistons christmas tree in the rebound direction.  By altering the metering of rebound fluid flow in this way, the rebound damping can be adjusted.

Being able to quickly and easily adjust the damping is something that gives you versatility for different race applications. From daily driving to autocross to drifting to drag racing, the ability to adjust the shock settings accordingly gives the driver the versatility to compete effectively in different types of racing environments. As any enthusiast would agree, that’s a pretty good bang for the buck.
