Mr Latte,
Do you recommend against only two transducers on both sides of seat for 'Chassis mode'? What kinda feedback would you miss out on when you only have two transducers as opposed to four, or stereo as opposed to quad?
I recommend people do various placement tests for their own cockpits and tactile. Most people just want a quick install and get going, generally they wont experiment. Yes on some cockpits moving the tactile around might not bring big differences but it is dependant on what the user has. By doing placement or installation tests and considering isolation is how you determine that you are getting the most out of what you have or find personal preference too. You may find lots of help but plenty of waffling in the "Mr Latte Question" thread as it covers lots of different factors or ideas and Simvibe potential.
With 2 tactile on Pedals and 2 on seat you are better representing the front and rear wheels. From an immersion perspective you are also incorporating your feet and not relying only to your butt/thighs to detect 4 directions or individual sensations. Also having 4 individual channels working against each other on one confined surface area will perhaps introduce tactile cancellation issues.
On a seat you will feel the vibrations going into your sides and back region it just depends on various factors of the installation,materials,tactile used etc. If you include more body regions then how your brain detects/perceives the immersion will in my view be a better experience.
Do you have a bucket seat, a recliner seat, these are factors that are important to maybe what you should consider. Some recline type seats have internal metal structures that help transmit the tactile. A bucket seat does not but is mainly one solid mold component. I have owned both but used different installation methods for both due to their structure/design.
Some alternatives to consider like do you go all in to your max budget now with more entry level equipment, or do you get fewer but better components and start with higher performance tactile/amp running only perhaps STEREO but working towards building eventually a much better performing set-up?

4 Units on Seat
Having 4 units working as CM on the seat was something I considered and still could do if I wanted with my own config but really the seat alone might not be big enough region to properly convey the transitions or distance of four wheels. I opted to run 2x sets of Rear tactile for greater dispersion but use mine in a unique way operating also with dual LFE for low end performance and an additional unit on the back of the seat for engine enhancement. So 7 units working on a seat but working in unison not all on different channels is a very different thing. Basically it is the REAR wheels and 1 Extension taken to the extreme.
I am not saying some success with all 4 CM on a seat isn't possible but with even brushing potential tactile cancellation aside. It is likely that the felt sensation from the front wheels to the rear will become harder to determine their actual differences. Berney from SimXperience once talked about this and was against it, saying such was too direct with the tactile on the seat from the point of installation to the time/distance of you feeling it.
Again I highlight that with the inuke DSP it is possible to get a work around for this issue of using units in a small confined configuration like a seat or even on a smaller cockpit using pedals/seat. You can add digital delay to the signal for the Rear which helps give a greater sensation of spacial presence/size between the front/rear wheels. Although physically they are beside or close to each other the usage of delay can give the impression they are further apart.
I know these replies are long, bad habbit but think you need to consider how far you want to go with it or how far you think you might want to take it. Best thing to do is in one of your threads add pictures of your cockpit, bring in your own personality and thoughts/concerns/desires you want from it and people will likely respond better than to just questions. Many will be able to relate to what you want to do or may be considering similar in the future.
This thread was meant to be more about tactile components but I never finished it, maybe one day though. I got a bit annoyed putting in all the effort to help others yet nobody still even yet in buying the ADX units responded to my query of them and the Aura Pro. Something I wanted to learn and understand myself.
Also the Question thread became very time consuming...
