Car Jumps

Hello Lads:

Anyone know why my vert jumps when it hits uneven road? i.e., when you hit rough patches of road at at 25+ mph, the car will lose contact with the road and skip or jump a foot or so.

I recently installed anti-sway bars but this has not helped.

I've got 245/45/17's on the front and 275/40/18's on the rear.

Weak shock absorbers? If there's a lack of damping going on then the wheels will hop over bumps etc.

Thats pretty interesting and dangerous as hell. I'd definately take a look at the condition of your shocks and struts.
