Intrax Racing Suspension
Intrax is a Dutch manufacturer of high-end suspension technology with over 30 years intense experience at the highest levels of racing. Intrax designs and produces shock absorbers, springs and suspension technology for Formula 1 cars, street cars and everything in between. In addition to an elaborate street- and competition portfolio, Intrax also delivers tailor made “one-off” suspension solutions.
R-developments is proud to present that we can now exclusively offer the complete Honda Trackday line. We are developed an exclusive trackday RS / RSA set together with intrax racing. Suited for the Honda Civic EG/EK and the Honda Integra DC2. The sets are specifically designed for hardcore trackday use.
We take suspension serious. Therefore we offer for most applications different settings on the spring rates, shim stacks and damping pistons:
- Fast street / occasional trackday. An upgrade to the sportive side from the OEM equipment. Daily comfort, vibration and noise levels are just as important as handling.
- Trackday / bumpy race circuit / Nordschleife. A suspension to race on both smooth and bumpy circuits. It is possible to ride to- and from the circuits. Ride height is enough to drive on public roads. Laptimes and handling are more important than comfort levels.

Intrax Racing RS
Depending on the application these are height adjustable coilover kits / separate shocks. They are the next step in improving the handling. The RS damper is a high-quality damper build from the same parts as our racing damper. This damper is based upon the same technology that helped Schumacher to his world championship.
The RS damper has a build-in hydraulic bump-stop. When hitting a big bump (like a speed bump) the damping is tripled to prevent the car’s body from hitting the tarmac. This enables you to drive
the car on the street in a very “low” ride height without any clearance problems.
Intrax Racing RSA
The RSA is an RS with externally adjustable damping. The internals are more complex to give an even better damping characteristic. Different from our competitors, Intrax chooses for one single
adjuster knob for both the compression and rebound adjustment. With this single knob the total damping can be adjusted over a wide range of 40 clicks from “comfortable” to “sportive/hard”.
By using one knob the relationship between compression and rebound always stays correct. Also different from most of our competition, our adjuster changed not only the rebound but
also the even more important low-speed and high-speed compression damping.
The RSA has an internal thermostat that keeps the damping constant, avoiding the harsh ride in the cold morning, and the loss of damping in the heat of the battle. A special version of the RSA
is the RSA-HDA, which features a piggyback remote reservoir. This reservoir improves the comfort and damping over big bumps, like potholes and curbstones. The RSA-HDA is manufactured in stainless steel.
Intrax Racing 1K2
piston rods, improving comfort, reducing oil temperatures, improving traction and extending life time under the severest conditions. The “Black Titan” is a luxury which – if you can afford it – is certainly
recommended. When there is sufficient room available, the 1K2 can be equipped with a “spring rate adjuster” which makes it possible to change the spring constant without removal of the struts/springs.
Intrax Racing 4 Way
The 4-way is our top product. The low-speed compression, high-speed compression and rebound damping is separately adjustable. The low-speed compression damping controls the front-rear and left-right movements of the car (“pitch” and “roll”). The high-speed compression controls the movement of the wheels over sharp bumps, like marbles and curb stones. The rebound damping controls the body movements and absorbs unwanted energies, which otherwise would unsettle the car.
The 4-way can be equipped with spring rate adjusters and the “Black Titan” coating.In special applications, if the physical room allows us, we can fit the “XL” version, upgrading the diameter from 45 to a huge 50 or even 52mm.
