Is it from the impact hitting the asphalt? If so, can a skid plate help?
Take some of the weight off the top, place it on the bottom using brass, raise height by 0.5mm to offset.

I usually raise the height by 6-7mm when I take my cars outside. This is another reason why I hate taking my cars outside because I have to change the setups back and forth between parking lot and my track... with the M05/V2 tracking issues with the rear left ride height, just a hassle dialing it back in while perfecting the even wheel gaps with the body as I like my models to look like real cars.
