Amazing work !
Nicely engineered and a great value !
And the support is top notch… Highly recommended. 
(if you want to build most of your rig yourself, Stage I & II are perfect to save a lot of time and research – and money)

Thank god, being fast in simracing doesn’t require to be rich.. :)

What do you mean by oversteer to late ?
With Stage I & II, you only have 2DOF, and you need 3DOF in order to feel the loss of grip, if this is what you mean. 
Stage I is 2K, but Stage III needed for the 3DOF and this is 5K…

If you live in the US, though, nothing stops you from upgrading from a Stage I to use a third SCN5 actuator.

Stage I is what most casual motion sim racers have (like myself, but self built) and it’s already REALLY REALLY nice. Seeing it in a video doesn’t do it justice, you really have to try that kind of motion system to understand the level of immersion it provides.

It’s a seat who moves independent from the steering wheel and that’s just wrong.

Can you enlighten us as to why it’s “just wrong” ? Any scientific argument to support your claim ?

Seat is bolted to a frame in a real car…seat does not move left/right.  Wheel bolted to same chassis…does not move left/right like seat.
Now we have this, you are being moved away from the wheel at each turn, both should be bolted together moving as one to be truly realistic.  Now can you enlighten me and show me a car where this happens in real life.
Its a nice rig don’t get me wrong, it just needs that 1 fix to be better imho.

 Or remove the actuaters, swing for loss of traction, and just strap it to this and you have a mega-rig.  It’s only money right? http://www.youtube.com/watch?NR=1&v=7zgKDgTIfgk&feature=endscreen

That’s because you probably don’t understand the underlying principle of proprioception.
Do you think that guy (and the whole x-sim community) would spend so much time on a rig that “doesn’t work” ?
Believe me, it works VERY well. It feels VERY realistic. Precisely BECAUSE the wheel doesn’t move. Your arms and legs are pushed against the wheels and pedals when you break, as in real life, and they get pulled away from the wheel when you accelerate, like G forces do in a real car.
It may look weird from outside, but I can assure you, when you’re driving that thing, your brain is completely fooled. Much better than a similar rig with the wheel moving together, like the D-Box systems (and D-Box are simply unaffordable for just a shaking chair…)

If you want to move the screen and wheel with the chair, you need very fast, very strong and long course actuators. You’ll only find those in pneumatic systems, and then you need 6 of them to do a full 6DOF with full motion, be prepared to spend a few tens of thousands more than a SimXperience rig.

You’re onto something there.
Indeed, those actuators (SCN5) are VERY fast and accurate : 400mm/sec with a precision of a tenth of millimiter. They are japanese, and the whole system has been discovered by Frex – the guys behind the Frex Wheel and the curved dome screen.
With such a rig, you can feel every little bump in the road, acceleration and deceleration, etc.
And it’s even better when you add transducers to it, like ButtKickers or bass shakers…

I’ve got the Stage I and love it! Hopng to upgrade to Stage II soon.

you feel when youre understeering (GT5 is a great example), you can feel when the wheels are blocking (fanatec pedals)  but you dont feel oversteering and if you notice that youre oversteering its to late. so if youre can feel oversteer with this. than you have it all!!!! 

 Well I feel strongly that motion simulation is a gimmick for people with too much money. Even in F1 it was not used by all teams aparantly. Sure there is a whole science about vestibular workings… Even a F3 car is a fast violent beast, I highly doubt you can give reliable cues to the brain with a few cm motion and nought point not much g force available in motion simulators..

And that is the $100.000 + systems, let alone a wobbly chair that gives you *INVERTED* g cues most of the time.

Immersion? Sure. Vertical ‘g’ feedback from bumps, yes that could work. Moving the seat only a bit in the wrong direction, while simming with a Logitech momo (horrod) on a TV with 0.1 second lag? That has nothing to do with simulation really!

end rant.. :)

It is about sim racing and not real racing.  So what does this mean?  It is about immersion, tricking the brain a bit (like we all do when we look at a screen/monitor {yes we do know it is not a windshield and real life out of it}), and this is aided incredibly by motion ‘cueing’.  Not replicating actual movement that a car does in the real world (you may as well do it for real if this is what you are after), but movement (cueing type) needed by sim drivers so that a greater connection and thus immersion is created for the sim car and sim driving/racing.

I drove a similar system at the Long Beach Grand Prix, and once I relaxed and connected I was amazed.  It was so much fun.  I was even a bit tired and hurting a bit in all the right areas and I loved this!

Hey Niels,

Have you tried this kind of simulation for yourself ?

It’s not only for people with too much money, I built my rig myself for less than 1500€ (and 3 months of R&D :p)
It’s not very different from your custom wheel, and it’s a very interesting engineering process. Actually, X-Sim can be used to generate the FFB of the wheel and get all kind of data from the simulation software (gauges levels, speed, etc) to output to all kind of hardware…
