NEW FUSION VALVING

Over the past 6 months MCA have been working on a new valving that is now refered to as “Fusion Valving”. It was given this name due to it’s ability to blend comfort and performance together even better than we have been able to achieve to date. The outright performance potential of this valving style compared to previous/current styles is similar if not marginally better, however it creates significant improvements in stability, bump handling and comfort without compromising performance. This creates the added bonus of increased versatility for the damper adjustments and each setting is now very useable all the way down to full soft. It’s perfect for either sporty or high performance road and track cars that still require acceptable compliance and ride quality.

HOW DOES MCA SUSPENSION COME UP WITH THEIR SUGGESTED SETUPS?

Firstly we start off with a relatively standard car and weigh it on all four corners. Then the amount of travel we want is decided on, this includes bump and droop travel. Then the shocks are valved according to what we think is correct. Once valved the shocks are dyno tested to make sure we are happy with the graphs and to check adjustments. At this stage we also decide where the adjuster should be set. Then the shocks are assembled but without bumpstops and springs then fit them to the car.

Then by adjusting the position of the base (bottom mount) we work out the closed length by jacking up the suspension assembly with and without tyre to make sure everything is clearing everything, but using as much travel as possible. After that we drop the shock down from full bump the amount required to achieve our desired amount of bump travel from ride height. Then we take measurements of the shock at it’s full bump length, its ride height lengths and full droop length. The shocks are removed and reassembled with springs and bumpstops ready for final fitment.

Using some maths we are able to move the spring seat into the correct position to achieve our desired ride height so there’s less fiddling once the shocks are on the car. After they are fitted to the car, we drop the car down onto the ground and check the heights to make sure they are as they should be. After that we need to check arm angles and roll axis to make sure that we are happy with this area, or to fine tune the ride heights to achieve the a good setup.

The vehicle is then driven on a bumpy road to make sure the track setup isn’t too unlivable as a daily setup. If it is, steps are taken to try and fix this, but in doing so we make sure to never reduce the outright performance. Then it’s time to take it to the track and test our setup properly. Generally all that’s needed is small adjustments to the roll axis and adjusters are made to find the ideal setup.

The car is then taken back to the workshop and final measurements are taken from the car so that it can be duplicated easily on the next set of suspension we put together for that model vehicle. Then we are ready to offer this suspension set at our suggested setup to the public.

Comfy!
Color: Black, Size: Medium
It's very comfortable. It's a good size and thickness. I wish it had a strap to hold it on to your air mattress or cot. Good value!

I purchased the toddler size as a back support pillow. Quality! Firmness!
Size: Kids 13"x18", Number of Items: 1
I LOVE this pillow! OK, I admit that I just got it and opened it, but I already know I'm going to love it. I purchased the toddler-sized pillow to use behind my back in the car or on an airplane - or maybe just a snuggle pillow in the bed - a tiny version of a body pillow. I got exactly what I wanted! This pillow is exquisitely crafted, and I can feel the cooling quality already. I purchased a brand new silk zippered pillow case for it. I inserted the pillow in the case right away because I know it's going to expand over the next 72 hours - to the perfect firmness, I hope. I'm afraid if I wait until tomorrow it might not be able to fit into the pillowcase! Some people here have reported a distaste for the firmness of this pillow, but I'm looking forward to it. So, I recommend if you want to really firm pillow, you had better put it right in the pillowcase when you get it, because you might not be able to stuff it in if you wait 72 hours! By the way, this pillowcase has absolutely zero smell, so don't bother your sleepy head about that.

Great pillow for side sleepers!
Size: Standard 20"x28", Number of Items: 2
I bought these pillows at first because I wanted to try out the “coolness” of them (I live in a place with no AC). They’re definitely not cold, but they do a good job of regulating the heat on particularly hot/stuffy nights. But my favorite thing about these by far is the support! I’m a side sleeper, and these are just the right amount of firm to tuck between your shoulder and neck that keeps your neck in a good position all night, while still soft and comfy for your head! I’ve been sleeping on them for about 2 months now and they have maintained their shape really well. Definitely recommend!

Great Pillow with Minor Inconvenience
Size: Body 20"x54", Number of Items: 1
When i got this pillow I wasn't sure if I was going to like it or not. It is not inherently lumpy like I thought it was going to be. It molds to you as you use it every night but resets as memory foam is meant to. My only issue with it is when it is packaged thru gold the pillow in half then roll it and vacuum seal it. Where that fold was there is a lot less fluff and no matter what I do I cannot seem to redistribute the fluff to even it out. Otherwise it's a great body pillow Edit: Still can't get the fold out if the pillow no matter what i do but I still really like the pillow. My mother just got the same one and she does not have any issues with the fold line. I am keeping my review as 4 stars but it really is an awesome pillow

I Sleep Hot and This Is The Only Pillow Ive Tried that Stays Cool!
Size: Queen 20"x30", Number of Items: 1
We have a closet full of pillows. I have tried a bunch from cheap to expensive, Sleep Number to Kohls. I sleep really hot, but I bought this pillow and it is crazy how cool it feels. If I get too warm and want it cooler I flip it over. I was doubtful but now Im sold. I winter in Arizona and Im buying one of these for out there as well. It's firm but fluffy soft. Great support for a side or back sleeper. Maintains its shape, the filling is cut up foam pieces of some sort but its super comfortable. I have not washed it as it had no foam odor, and I was able to use it right away. I definitely recommend this. Great pillow!
