when i hit around 80mph

when i hit around 80mph i get a jerk like pearl is dragging me down and to the right almost like im hitting a small bump. This "small bump" feeling obviously increases and is more apparent as acceleration increases. any ideas what could be causing this?

its your rear spoiler catching drag and putting weight to the rear wheels.

no, factory m spoilers catch drag at 80 mph.
