Sorry if my response was a bit vague. I had the exciters you want, directly on the seat. SIX of them. I no longer have them. I do have a pair of BST-2 units on the rear now to complement the rest of the build. I'm yet to balance and tune everything together, but they are 1000% better in terms of how much I feel compared to what the exciters gave me. I can only imagine how utterly useless they would be mounted to a piece of profile, let alone in at attempt at feeling a certain effect on a specific body part. Unless you strap that thing directly to the rear of the brake pedal, you won't get what you're after with those.
Also, I have no idea where this notion that ABS must ONLY be felt through the brake pedal. If anyone is familiar with the sound it makes in the cabin while active, they would know full well that the feedback is pretty high and there's no way that the feeling is isolated on a particular pedal. Do you only feel engine vibes through the throttle? Of course not, it travels through all parts of the car depending on the note and intensity of the revs. Anyone relying solely on a particular source of feedback for driving aids needs to seriously look at their driving. No shade, I'm a garbage driver, no issues admitting that. But I at least understand what's happening with my car most times and what I'm doing to get it to perform a certain action.
Tactile is a very individual experience. You can get as much or as little out of it as you like, once budget and time constraints are taken into consideration. We've all been down the path of, "this will do nicely", yet here I am recommending things that 12 months ago I was adamant I would never bother with.
The 1000D, I would seriously recommend going the 3000 and this is someone who right now is running a 1000D with a 6000 on the couch next to me ready to be swapped over. If you omit the "D"SP element and get the vanilla 3000, where I live it's actually cheaper to get the 3000. Many of us are using software DSP so we're not omitting it entirely but I have used it on the 1000D and I'm pretty sure with my units I'll achieve the same thing through software. It's a good feature to have, but a 3000 is 435 and the 3000D is 650 where I live. That's almost a TST 239 right there in the savings.
I would strongly advise that if you do decide to go with exciters, be prepared to stick those things directly to your seat. You also will not be able to power those with the 1000 if you're already running a BK on it. Unless you run them all in series from one channel, something nobody is doing. You'll need another amp, something like the EPQ304 is popular for those units. You get 4 channels of low/moderate power output, exactly what you want for those units. The Nobsound amps are pretty good for them too, but I'm not sure whether they come in 4 channel variants and as such, you might need a couple of them to get full functionality out of your units.
