If you drop the car from 2' and it bottoms out, that's typical, mine will too
If you try and stiffen it up so it doesn't bottom when dropped from 5' it will handle terrible

1/8th scales bottom out off jumps, they just do.
It’s how fast they recover from the bottoming out that makes them handle good or bad. If you have it so stiff that it doesn’t bottom out any little bump will bounce it into the air and your wheels will never be on the ground, you need to find the best compromise for the track conditions where you race.
