    Hi guys, just putting the feelers out for a production run of AUS-Spec Tein Monoflex coilovers. The new monotube design is a step ahead of flex or superstreet coilovers, with more control and less fatigue after a few hard laps.

    These would be genuine Aus-Spec from Fulcrum Suspensions, sold exclusively through Unique Auto Sport.


    Features include
    • Custom Aussie Spring and Valve Rates.
    • 16 way damping force adjustment for both front and rear coilovers.
    • Vehicle ride height and spring pre-load can be adjusted independently. Ride height is adjustable in two ways; adjustable shock length and adjustable spring seat for a greater range of adjustment.
    • Pillowball upper mounts
    • Mono Tube internal design is utilized for increased oil capacity, improved heat dissipation, larger valving, and quieter operation.
    • New microspeed valve system that allows for improved comfort through more precise oil flow control inside the damper.
    Price: Price per set would be discounted to $2235 for this group buy.
    Minimum Order: We would need ten buyers to go ahead.
    Timeframe: Open to suggestions, need expressions of interest first!

    Can these be set soft for comfortable road use? Remember, I'm an old fart.

    Yes, 16 levels of adjustment so you can set for your application.

    Also being aus-spec the spring and rebound rates will be softer to suit our roads.

    Whenever we have ten buyers :D We need the numbers to make up the order so I'm flexible with the timeframe.

    RedZedMikey RZM should now be DZM

    Compatible with EDFC?
    I had been considering a set of Fulcrum spec Super Streets; will need to research and find out whether I think these will be worth the extra $$$ to me. Don't consider me a commitment at this time, just potentially interested.

    Yes they are edfc compatible and will be a big step up from super streets. Let me know if you have any other questions, will do my best to talk you into it haha

    Excellent, good to see such a positive response already.

    what do u mean when u say?

    does this mean the tension on the springs can be adjusted...ie from say 10kgs front and 7 rear to lik 5kgs front and 4kgs rear?

    im still a bit lost when it comes to selecting a coilover...?

    what should i be looking for and how do u work out what type of driving it will suit?

    The actual spring rate cannot be changed. The preload can by moving the spring seat up and down. It will feel stiffer as more force is required to move the spring. If you have 10kg/mm springs and you compress it 10mm, then you will have 100kg's of preload, and the force required to compress the springs more must be greater than 100kg's.

    The height is adjusted by moving the shock body in relation to the bottom mount.

    I've driven a car with the Jap Monoflex's and I must say they are fantastic. Pretty comfy but handles amazingly!

    Ok when you are talking kgs etc you are talking about spring rates, which are fixed. Incorrect spring rates will affect ride stiffness/harshness and weight transfer (which will hurt performance at the track), hence why we are getting AUS spec coilovers with custom spring rates to suit our road and track conditions. The japanese and american spec tein coilovers have spring rates which are too stiff -we know this because fulcrum have worked closely with UAS over the years (including developing the first set of tein flex coilovers for Z32 in the world) with lots of track time and fine tuning.

    OK so now we have spring rates explained, the coilovers allow you to adjust the amount of preload on the spring, so as you can tighten it up for the track or soften the ride for the street. This is done either at the coilover, or can be done electronically in cabin using an Electronic Damper Force Controller (EDFC for short). Monoflex are EDFC compatible so you have the option.

    The height of these coilovers is also user adjustable, and adjusting the height will not affect damper adjustment (ride stiffness). Some coilovers allow you to adjust height but not damper, or damper but not height. These coilovers allow you to adjust both independantly.



    This is a bit of an open ended question... what do you want from a coilover? Heaps of height adjustment? Range of dampening adjustment? Something that will perform well at the track and on the street?

    That's not right Rob. The EDFC adjusts dampening, not preload.

    Isn't damper controlled via preload? Interested if you can explain the mechanics, have read a bit but i'm still learning! Thanks

    Preload is the springs.

    Dampening is the deceleration of the movement of the shock. The more dampening the quicker the shock will stop moving. If you didn't have it (and no friction) the springs would bounce on forever. This is often broken up into compression and rebound. Compression is the deceleration while the spring is being compressed and rebound is the deceleration during extension.

    The amount of adjustability that is available with aftermarket coilovers makes me very skeptical of so called "Aus" versions compared to the Jap and US ones. Just order some softer springs if you don't like it that firm. The Aus Flex's have the bottom adjustment removed if memory serves, which would remove the main reason that a lot of people would buy these... Are the Mono's the same?

    Cool thanks for the info.

    With respect to the tein products, AUS spring rates are softer (so compression) and valves (which control rebound) are different also. They are actually a different part number to the JAP and US market products.




    With the bottom adjustment, are you talking about the clevis clip for height adjustment? If yes then this is retained on both flex and monoflex products.

    The tighter you do up the springs (and increase the preload). The stiffer the ride.

    Springs DO NOT have a linear load rate increase as they are compressed. The more you increase the preload. The higher the force needed to compress them during driving. Making it much stiffer as you reach the lowest possible point.

    IMO after driving a car with these lowered to a bit less ( 1/2 inch more ) than the Eibachs. They are a poor choice for a road car. BUT would be great on a track.

    They do have a linear rate, otherwise why wold people buy progressive springs? :rolleyes:

    Your right in saying that it increases the force needed to start compressing them.

    I know that they say that they are revalved, but Nissan have different part numbers for the engine mounts for the NA, the TT and the 'vert...

    The rebound is normally adjusted with the dampening control on top of the coilover. The valving may change the overall ratio between the compression and rebound, that's about the only change I could see them making. Either that or move the total range of adjustment higher or lower.

    They are definately different -check out UAS motorsport pages, somewhere in there they talk about changing from jap flex to softer aus flex which resulted in better track times.
