The MCA Pro-Comforts are designed for maximising comfort but also incorporating a very enjoyable level of handling for street applications with a medium range of height adjustment. The boost in handling whilst keeping comfort levels high is thanks to MCAs latest valving, Fusion Valving, along with a more thorough and dedicated development program.

Suitable Applications:

Comfort prioritised street drivingEnjoyable spirited drivingFactory height down to 10mm tyre to fender gap (estimate)



Taking Bamber Spec to the next level, Rugged Spec literally doubles down by overhauling the major sealing component designs to build in sealing redundancy. Essentially this means all of the sealing points inside the dampers now have a backup. This is a relatively new design concept but we?re confident it will take the reliability and durability of MCA Suspension products to a whole new level.


Our dampers come with 12 clicks of damper adjustment between hard and soft settings. Each click is quite powerful and very noticeable. The way the damper adjuster works, is it controls the flow of an amount of oil that bypasses the valving system. Closing (setting harder) the adjuster restricts oil flow making the damper firmer and more controlled, while opening (setting softer) the adjuster allows the oil to flow easier which makes the damper softer and less controlled.


Our dampers come with height adjustment which controls the ride height of the vehicle. Contrary to most other products around this price point, MCA Suspension products use ?Critical Length Technology rather than ?base height adjustment? meaning that instead of using the bottom mount position to adjust the ride height, the spring seat position is adjusted instead. This is the same system as used on true, high end suspension products. MCA Suspension always builds as much height adjustment into our products as realistically possible, however the exact amount my vary vehicle to vehicle and product to product for a number of reasons.


MCA Suspension offers one of the best (if not the best) 2 year warranty around for suspension components. This warranty covers bushes, bearings, rubbers and seals. However we often cover more (this is decided on a case by case basis) as we strive to make sure that the experience our customers have when using our products is the best possible. One of the main areas we differ to our competitors is that we also go out of our way to help make sure that any warranty claims are handled in a speedy and extremely convenient manner.


All of our products are assembled in Australia by our highly trained team. All of our suspension setups have been designed in Australia by MCA Suspension. Unlike many of our competitors, no copied setups here. Even the large majority of individual components used in MCA Suspension products (including mounts, springs, internal sealing components, spring seats, shafts, etc) have been designed by MCA Suspension.


Generally speaking, regarding vehicle suspension, there are two types of dampers in the way that they operate internally. Monotube and Twin-Tube. Twin-Tubes often are cheaper alternatives and don?t have the same potential as Monotubes (for example, most factory dampers and cheaper factory replacement dampers are twin-tubes). MCA Suspension only uses Monotube Suspension, as does all true high-end suspension brands.


Having done rigorous testing with a variety of valving styles and configurations over the years, we wanting to create a new style of valving that bridged the gap between track and street use. Our goal was to remove the stigma that track orientated suspension has to be uncomfortable to optimise performance or that comfortable street suspension can’t provide effective stability at the track. The result of our efforts is FUSION VALVING! Fusion Valving achieves less compromise between comfort and handling, provides a wider damper adjustment range, and achieves silent operation throughout years of use.

Features Where Applicable:


Where-ever possible, MCA Suspension always features camber adjustment. Camber leans the top of your tyre in and out. Generally speaking, for road use, the straighter your tyre is (vertically) the more even the tyre wear might be, but the performance will lack. Leaning the tyre in at the top for more negative camber might help with tyre and fender clearance, and will also help improve the steering feel and vehicle performance, but may hurt tyre wear. For assistance as to what wheel alignment settings to run, please visit the technical section on this website. Please note: how the camber adjustment is achieved if it?s at the front, rear or both ends of the car will vary.


In the large majority of cases MCA Suspension products feature Helper Springs. A ?helper spring? is a light weight spring who?s job is to keep the main spring captive if a specific setup and ride height combination mean that when the vehicle is jacked up with wheels off the ground, the spring may be loose. Thanks to the Helper Spring, the main spring will be held up and seated even in these rare situations.


In most cases, except for MacPherson Struts, we will use our own design of rubber tops. These rubber top mounts offer the needed amount of flexibility while also offering stability and minimised extra movement. They are even used in our 1100rwhp, Red Series equipped Time Attack 86.


In some cases the factory design of spring and damper setup is to have them sitting separate from eachother. In these cases we will often keep using that basic layout and factory mountings.


The true meaning of the word ?coilover? is when a damper has a spring mounted around the outside of it. This is a common design of suspension for vehicles. In some cases we will be able to convert Separate Designs to a Coilover Design also.


When a strut type of suspension setup is used by the factory, there is the option to replace it with an ?inverted? type or ?non-inverted? type. MCA Suspension has used both designs over the years, but for products like Red Series and below, we use our non-inverted design in the large majority of cases, even for motorsport applications. Even our 1100rwhp, downforce loaded Time Attack 86 has run them for years. For more information on these, please visit our technical section.


Adjuster Extenders help gain access to the damper adjuster knobs in situations where the adjuster knob is hidden behind metal, trim or is simply difficult to reach. These are a rubber coated flexible steel cable with machined anodised aluminium ends which attach to either the existing adjuster knob, or screw directly onto the top of the damper?s shaft depending on the design.


Camber Washers originated on our Gold Series products, and are offered as an optional extra for some of our entry level products and come as default on our higher end products. However they are only for cars that feature Macpherson struts. They are used on the bottom mounts and offer superior control, reliability and adjustability. For more information please see our technical section.
