    Exclamation SWIFT Lowering Spring Kits & Coilover Upgrade Springs

    MFactory Competition Products / YCW Engineering are proud to announce our status as a newly appointed Master Warehouse Distributor for SWIFT Springs in the US, Europe and Asia

    We have available their full range of products including:
    - Sports Springs / Spec-R (To be used with stock dampers)
    - Replacement Coilover Springs (Upgrade your sagging coilover springs)
    - Assist/Helper Springs (Setup the droop on your coilovers)

    THE SWIFT ADVANTAGE:
    When drivers look at a set of springs, they concentrate mainly on the rates, but the material and manufacturing process is equally important. Most enthusiasts will tell you that all springs are the same... we asked some professional drivers for their opinions:

    - I just replaced my springs to Swift Springs with same spring rate, and somehow the car behaves totally different now.
    - Since I've swapped the springs from another brand to Swift, my lap times became very consistent throughout the entire race due to cooler tire temperatures, which saves tire wear.
    - We have tested our Swift-equipped race cars on a shaker rig, and the Swift Springs have a lot less harmonic vibration.
    - My car is a lot smoother with Swift Springs even though same spring rate were chosen, especially on bad surfaces.

    The many positive comments Swift Springs receive would have you believe that Swift Springs is surprised to hear such things in the first place, we are simply getting confirmation that our engineering not only works on paper, but is also proven through use in the field (track). Now, allow us to provide a few reasons as to why we get this kind of feedback from our users.

    PRIORITIES THAT WE ALWAYS HAVE IN MIND WHEN WE DEVELOP SUSPENSION SPRINGS:
    Surely you have read some spring manufacturer's catalogues before, and you have read that they all claim to have the 4 factors listed below.

    - The most consistent spring rate throughout the stroke
    - The largest amount of stroke
    - The highest durability against loss of spring height
    - The lightest in weight

    We like to believe that all suspension spring manufacturers try their best to achieve these 4 factors. Top suspension tuners know that these 4 factors play an intricate role when considering the effectiveness of the suspension coil spring.

    Our parent company, Tohatsu, has been winding industrial springs since 1924. Tohatsu then decided to get in to the auto racing market in 1996. Based on long-time experience dealing with coil springs, we came up with one goal: "We must make the product that will revolutionize the ones we see on the market now." Keeping this goal in mind, we went back to the basics of coil spring design and asked ourselves what is the most important factor that we need to consider on this new project.

    The answer?

    MAINTAINING TIRE GRIP IS THE KEY TO FASTER TIMES AND SUSPENSION SPRINGS TAKE ON AN ENORMOUS PORTION OF THIS TASK!

    All Springs are not created equal, the diameters and spring rates can be similar, but the process of manufacturing springs plays a huge factor in how they will perform. Through our extensive knowledge in performance springs, we have perfected the process of manufacturing springs that will outperform our competitors.

    With this in mind, we set out to produce a new material for coil springs: a proprietary steel alloy we call "HS5.TW". This material was created in order to maintain the 4 factors listed above, as well as achieving the fastest reaction speed possible to get compliance on road surface conditions. Our springs are created with proprietary winding methods, as well as some other trade secrets focused on ensuring our springs separation from the standard market.

    In the time since Swift Springs officially opened its doors in 1997, Swift Springs has dealt with many world class race teams in multitudes of different races including road racing, rally, off road, drift, autocross, pavement and dirt oval track, motorcycles, and more. Swift Springs has lifted many racers to a podium finish, and is still continuing to do so. With so much experience behind us, we feel confident that our springs will give you a leg up in any kind of race you participate in.

    Try Swift Springs on your vehicle, and experience what many racers are talking about. We strongly believe that you will feel the difference just like every other racer, and you might even wonder why you didn't try it sooner.

    THE HISTORY:
    The origin of Swift Springs
    Swift Springs was founded in 1997 in Tokyo Japan as a motor sports division of Tokyo Hatsujo Manufacturing Co, Ltd. that has been leading the spring industry since 1924

    The purpose was to demonstrate our superior engineering in spring by developing the next generation of motor sports suspension coil springs. They had to have the best characteristics of any brand or design in the market, which required the springs to be the lightest in weight and most durable, and to exhibit the most linear characteristics while still being cost effective.

    Since the formation of Swift, it has been lead by the former racer and suspension expert, Kei Yokota, and the chief engineer, Yasu Saito.
    Their first-hand involvement within the race industry has propelled Swift quickly through the ranks of some of the world’s most reputable races. Swift springs quickly became one of the most recognized and respected name in performance coil springs in many genre of motor sports throughout the world. Being a part of the Tokyo Hatsujo spring corporation. Swift has a large collection of engineering research and development resources. Tokyo Hatsujo springs are used in most light to heavy industries and the dynamic has provided Swift with most advanced spring technologies and innovations available.

    In Swift’s impressive motor sports history dated back to 1998, first was with Nissan Skyline GT-R in the Super Taikyu Endurance championship series in Japan. Then Swift got involved with the championship teams in Le Mans 24hrs, Nurburgring 24hrs, Super GT (JGTC), Super Taikyu series, D-1 World Grand Prix, F3, F3000, Formula Toyota, and many other world class races.

    In 2004, Team Goh Audi R8 won 1st place at the world renowned Le Mans 24hrs race on swift springs.

    60mm ID only goes up to 9"

    Closest you'll get is the 60mm ID 9" @ 12K/670lb or 65mm ID 10" @ 12K/670lb

    Are you trying to keep stock height? I wanted to keep stock height on my 135 but could not find any coilovers /springs that could accommodate that option. Since you are in europe you might have access to different venders than i do. I only real solution I know of is to have custom springs made some companies offer it.

    Mfactory, I was in round 2 of the beta testing for the YCW coilovers and would like to upgrade to the Swift springs when they are available to order. When/how would I go about doing that?

    To get my ideal spring rate would take a full day of work and you may have some experience in e92 shock/spring measurements when loaded that would save me that time.

    Looking for ideal rear spring rates for

    -e92 335i / M3 rear spring carrier arms
    -Corners weigh in at approx. 815 lbs
    -Rear fenders lip will be ~25" high from center of lip edge to ground
    -Looking for 40/60 bias towards compression/rebound available spring travel
    -shock travel is 6" and would like static height at 2" compression


    Long shot but figured I'd ask.

    Do you already have coilovers, or were you looking for just lowering springs?

    If that was directed at me, yes, these are for Double Adjustable Koni/TCKR shocks

    I'm finally able to shop around installers. I am curious to how much it's costing everyone for install?
