I will give you my answer I am not sure its the right one, I think the Fat Cats are better than the OEM Mazda as they are real hard and if you get into them your going to go for a ride most likely, the fat cats will be progressive there is a transition to bottoming out. Also i recall reading some place that they will change the geometry of the shock to the control arm, not sure about that.
Yeah, I can think of an occasion that surprised me. Maybe that was what happened.
I'm probably not being clear with my question though...why are bumpstops so important (in any racecar) if you should rarely be at full shock compression? I just assumed SMs relied on them frequently because of the limited shock travel.
You should be able to safely run the car lower, a little, by using them vs the hard rubber stops.
someone smarter than me may have the right answer.
