This is especially true given the design of most coilovers for this car as without shorter housings it is very difficult to properly tune the suspension given the factory design constraints. There is no coilovers out for this car that I am aware of that uses the bump stop in the same manner as oem which leads to a necessity of shorter shock housings or higher ride height for additional compression travel.
Use it as a bump stop or as a progressive secondary spring? Bump stop is not a travel indicator and shouldn't be used as such. If used correctly there is actual benefits to bump stops to increase cornering power though added mechanical grip. Spring rate can be a factor as well, but that is a different topic.
