The following review comes to us via King customer Andy Thompson - thanks Andy!
Skunk2’s Pro-C Coilovers are a solid choice for an all-inclusive, mid-level suspension offering features beneficial to track-specific applications.
Why I Chose Pro-C
I initially set out to find an authentic suspension that offered modern coilover features and chassis-specific production. Although many with newer vehicles will not have this issue, my dated EF chassis has quite limited aftermarket choices. So the Pro-C was one of my only choices.
Skunk2 designs and tests all of their products, specific to application. This is important because the coilover actually matches the intended chassis it was designed for, instead of a coilover that was originally designed for one chassis and has been translated to fit others.
I wanted a fully-inclusive suspension that had springs matched to struts, versus a two-piece spring and strut combination from two separate manufactures. I wanted fully independent adjustability in spring rate, dampening, and ride height. The Pro-C smartly offers ride height adjustability independent of spring rate. With many older suspensions, changing ride height also adjusts the spring rate as a negative side effect.
I was also interested in an inverted mono tube strut to maintain a larger oil capacity while offering strength and responsiveness. The Pro-C does not offer inversion, but still uses a mono tube design versus an OE style struts twin tube design (which can feel unresponsive in performance applications).
Here is a comparison of the EF OEM suspension versus the Pro-C:
The Pro-C offers a relatively simple and effective valving system. Removable keys on the top of the strut easily control dampening. The keys are retained to the top of the piston rod via rubber o-rings, which allow them to be left in place during driving.
Many lower quality suspensions advertise 36-way adjustability, which is fine, but can be quite frustrating to keep track of and count out when readjusting damping. With Skunk2 offering 12 points of adjustability, it gives the user enough range to dial in damping with meaningful differences between each click. I currently have my suspension set at 3 in the front and 5 in the rear, for casual street driving.
CNC Machined Aluminum Strut housing and Spring Perches
If you live anywhere with rain, snow, or dirt; aluminum threading and perches are a huge deal. A common issue with lower quality aluminum and steel struts is corrosion, and trying to adjust spring rate after any amount of time usually involves ditching the spanner wrenches and grabbing a punch and hammer. The Pro-Cs are made of 6061-T6 aluminum, which is a tempered grade. This makes the threading much more corrosion-resistant and spring rate adjustability a feature that persists despite your weather or road conditions.
I have two summer seasons on my coilovers, in which they still adjust with ease after road grime is wiped off. I personally apply silicon lubricant to threading to repel water (although road grim builds up quicker but is easily removable).
Contrary to what is advertised, these coilovers are by no means comfortable. With almost no spring load and low dampening settings, you will still be feeling every crack in the street. On the other hand, the feeling is confident, and there is a total absence of slack in the system. That said, make sure the rest of your suspension system and bushings are up to par-- if not, expect the soft spot in your system to be amplified.
Clearances with UCA
Although this is not a coilover specific issue, some double wishbone suspension setups with front camber kits may run into clearance issues with certain degrees of camber. On my EF, I am running an irrational 4.6 degrees of camber in the front, in which occasionally my front knuckle knocks against the springs and spring perches of the coilover on larger bumps.
If you’re a Honda enthusiast looking to get involved in some motor sports such as local auto cross events or open road racing events -- while still being able to drive your car on the street -- this is definitely a great choice.
If you’re planning on driving your car every day or commute long distance to work, the Pro-C may not be for you. Or consider purchasing the Pro-C with lower spring rates.
I am constantly tinkering with my suspension and plan to try a different set of springs for summer 2015. Thanks for reading.

The riveted metal Mugen badges are commonly found on front lips and aero pieces. These badges were included on many previous-generation, discontinued Mugen body pieces that circulate the secondary market. Given enough time, miles and repaints, the badges have become one of the only remaining indicators to tell a genuine apart from a replica body part. There are few ways to spot a replica/fake metal rivet badge:
1. Packaging. If the emblem does not include the proper package (or no package), it may be a replica. Note that Mugen have not sold the badge in the colored red-gold-black diplay bag, only the more generic bag.
2. Painted versus embossed. The genuine badge is embossed on sturdy metal. If you run your finger over it, you should be able to feel the logo.
3. Logo spacing. The replica badge has extra spacing around the kanji and MUGEN logo. The genuine has an overall tighter design with less space around the kanji and MUGEN logo.
Here is a comparison photo of the packaging.
