Ok, it'll vary depending on your tire size and gear ratios, but the point is the same. You'll be getting into them in a low speed, tight corner. Not very accurate and you're probably getting into the stops a lot more than you realize. Sitting on the stops when accelerating out of a corner does not have to be 'harsh', but it will increase the effective rate and hurt rear grip. Removing the axle mounted bump stops wouldn't hurt the konis. I'm pretty confident they wouldn't bottom out before the axle does into the framerail. But it's your car. Do what you want. Not sure what that means. From what point of reference? Upward angle going from front to back (front chassis mount lower than axle mount) or vice versa?
