Suspension Question
Every now and then I’ll hit a bump in the road or a speed bump, at about 20-30 mph, and it feels like the front shocks are bottoming out. On one occasion when this occurred I felt it in the steering wheel too. In all instances, I was in Sport suspension mode, as I leave it on all the time.
It doesn’t seem normal. Does anyone else experience this or have any comments?
Thanks

Do you have SPASM? Personally I have found that SPASM does not have enough suspension travel and my car, when stock, felt like driving a lowered car so your observation is not very surprising… of course if you have regular PASM, the car should have a better ride and shouldn’t be bottoming out. I though stock PASM rode extremely well and handled very well. Unfortunately the car looks too high w/ stock PASM.

That might be too fast for a speed bump...20 to 30 mph (especially 30). Most speed bumps in Virginia where I live are designed for 10 to 15 mph rollover speeds. You can too a lot of damage to a car with too much speed hitting obstacles that fast, including damaging shocks, bending wheels, pinching tires, bending control arms. Rather than looking for a mechanical solution, perhaps slow it down a bit when crossing those? The only time I will cross speed bumps at more than 15 mph is in my pickup truck.

i've had this happen a couple times to me. Not on a speed bump, but while driving on back roads, a part of the road that goes up then down quickly. Felt / sounded like i scraped something underneath. So far, haven't determined any damage so hopefully not a big deal.

Speed isn’t the issue. I’m not referring tall/abrupt speed bumps. These are gradual and low made for keeping your speed down in the hood. Whereas I agree with you on the tall abrupt speeds bumps made to force you to barely roll over them.

i think most of us would still argue that 20-30mph is still too fast. I do 10-15 in this car and I don't even has spasm.
