hooking problems

Put more air in the rear tires looks like it sways at speed. Most guys running et radials are in the high teens, low 20's.

Get a better pair of rear shocks to control the axle/body separation. Looks like the car jumps and unloads. They could be too short.

The front of the car doesn't look like it works at all, maybe an inch or two of travel. Try to get it in the 5" range.
