They sit inside the spring stacked up. IIRC I have either 3 or 4 on the rears which limits the suspension travel to something like 2mm with zero droop. I have one less on the front but quite a bit of droop dialed in. This ensures that my car is always raked no matter how hard I press down on the rear and the front never bottoms out.Good point, messing with the ESC throttle curve is more accurate and easier than trying it on the RadioLink. I can add just a touch of negative exponential curve, ... I think that is negative? Either way make it look like that. Got it.
You're describing a bump stop. Which, on a real car, prevents you from smashing your axle/control arm/whatever into the frame, which is bad. Riding on the bump stops (done that before) does stiffen the suspension but effectively makes an infinite spring rate and makes the ride super choppy and uncontrollable on a rough road. Small bumps under throttle or braking causes the car to skip and dart.
The nitro tubing is installed in the rear, which ash you described, is a PITA to install. Raz made it look so easy. But I either didn't use enough of it or it's too soft for the amount of down force I have.
I have a lot of ABS plastic and can try the discs like you have. Or I might be able to just buy some plastic washers and split them and wedge them on to the shaft. What do they look like installed? Do they sit under the spring above the spring cup or inside the spring stacked up?
You are correct that setups like this are less than ideal for rough or choppy roads. I guess my reply to that would be - rough and choppy roads are less than ideal for speed running and will definitely make finding an ideal setup tricky, to say the least.
