Hi all, I ask your help to understand how to manage the setting values in AMS1. That's because there is not a manual about how bumps/rebounds work in AMS1. So may you please tell me if what I write hereunder is correct ? If car UNDERSTEERS under acceleration while turning · Decrease FRONT REBOUND (front will resist extension) · Increase REAR BUMP (rear will resist compression) If car OVERSTEERS under acceleration while turning · Decrease REAR BUMP (rear will compress more easily) · Increase FRONT REBOUND (front will extend more easily) If car UNDERSTEERS under braking and turn in · Decrease FRONT BUMP (front will compress more easily) · Increase REAR REBOUND (rear will extend more easily) If car OVERSTEERS under braking and turn in · Decrease REAR REBOUND (rear will resist extension) · Increase FRONT BUMP (front will resist compression) Is that correct or is the opposite ?
Decreasing front-rebound will not slow down (ie. "resist") extension. Increasing front-rebound will slow down ("resist") extension. Decreasing front front-rebound will speed-up ("more easily") extension. On one hand, decreasing front-rebound may increase understeer because the front extension resists less so the weight will be shifted from front to rear faster. On the other hand, decreasing front-rebound may decrease understeer because the front extension resists less so the weight will be shifted from inside-front to outside-front faster. So decreasing front-rebound can increase or decrease understeer. Increasing front-rebound will make the front extend more slowly (resist more). Increasing rear-rebound will make the rear extend more slowly (resist more). Decreasing rear-rebound will make the rear extend faster (ie. more easily). If you want to slow down the extension (ie. make extension more difficult), you must increase (harder) the rear-rebound. - Higher # = more damping = stiffer = compress (bump) or extend (rebound) slower (more difficult) - Lower # = less damping = softer = compress (bump) or extend (rebound) faster (more easily) Some times dampers can do the opposite for pure turning (no acceleration) and pure acceleration (no turning). For example: - softer front-rebound can give less understeer (or more oversteer) during turning because it makes weight shift to the outside tyre faster. - softer front-rebound can give more understeer (or less oversteer) during acceleration because it makes weight shift to the rear tyres faster. So it's a complex balancing act because softer front-rebound should give more (or quicker gain) front-grip in terms of lateral weight-shift but should also give less (quicker loss) front-grip in terms of longitudinal weight-shift. So which one takes precedent?
