    well I´ll try to aproach to the 120% and test it but first i´m going too show two videos with this config. Want your opinion, thanks.

    well well well, here is the first video. Simply acelerating/ breaking forward and reverse

    The second one a bit larger but interesting to see the final crash.

    Racing and finally crashing on life for speed

    The videos are Private, you will need to make them public so we can watch them.

    Great~I also got my 2DOF sims soon~~I think your profile can be fine turn to get more impact~~

    Just some suggestions for you to consider, as I think you do need to refine your motion profile.

    You are missing a lot from a lack of refinement, particularly with heave. You seem to be hardly registering the bumps down the long Blackwood back straight or over ripple strips.

    While you have plenty of surge and sway axis movement it is not particularly sharp and defined.

    As a test turn the other axis off and set the heave Axis allocation at say 15% and the Tuning Center value at 2. You can go below 1 to something like 0.5 if you need to, but what you should feel is the bumps, and vibrations when you run over the ripple strips.

    another question, may I use also some of yaw or it´s only for 3dof motion seats?

    Yaw is more for flight sims than racing, so don't bother with it.

    Get heave, surge and sway sorted, they are the most important for a race profile. Once you are really happy with them you can experiment with roll and pitch.

    thanks a lot!! well, the first thing to do, the gforce feeling, then the car movement. trying and comenting.
    For example 40% of surge 40% sway and 15% heave. Must I change also the tunig center for this values?

    After making a lot of test and following the advices of noorbeast(thanks). finally y change the settings.
    Acelerating, braking, lateral forces and the bumps and vibrations feels great. IMG_20160518_184130.jpg

    I know that is axis percent is 120 %. There is no space for roll and pitch, but adding 20 % of each, doesn´t affect negative on other movements. IMG_20160518_184141.jpg

    I think this could be cause heave and pitch are opposite to surge, and roll is opposite to sway in my configuration. And in the case of for example the sway,heave and roll moves on the same values of the axis. They never pass about the 80%. The same way if pitch+surge+heave in the same direction never gets more than 95%. So if another strange situation come to the sim, the input limit doesn´t let the axis go for more. As i appreciate the sensation is great in every moment.

    any idea how you're gonna minimize the sound of the spring? (if at all?)

    yes, the part of the springs that make noise is the end of then , where they are tied to the structure. I,ve been thinking about to tied with screws and nuts. this way te sujection is hardfixed, and the clerence will be supported by the springs themselves
