Wheel hop issues
Whenever my tires break loose, I get severe wheel hop. Is this typical? I cringe every time because I don't want to break something. Any fixes? Thanks.

Re: Wheel hop issues
How old are your tires?

Re: Wheel hop issues
About 4 year old PS2s. Been the same since they were new. Hot or cold doesn't matter.

Re: Wheel hop issues
Have had this issue since I got the car. Both with stock fx3 suspension and fx3 coilovers.

Re: Wheel hop issues
Perhaps the shocks are failing and losing their ability to control the axles? Usually wheel hop results from a poorly controlled axle; you experience what used to be called axle windup. My solid axle '68 Hemi Roadrunner had a lot of wheel hop with its solid axle but I fixed it with a set of stout traction bars. That wouldn't work on a ZR-1's independent suspension but it was great back in the day. And usually an additional recommendation was better shocks. --Bob

Re: Wheel hop issues
Yep I remember that. My FX3 was functional and shocks not leaking. Replaced all oem rear suspension rubber bushings with Energy Suspension polyurethane. I left the batwing as oem. I also replaced the shock bushings with polyurethane. I had to call Energy to figure those out. Problem solved. No hop even at drag strip. BTW get the black bushings.

Re: Wheel hop issues
Mark replaced all my bushings a couple of years ago with the purple poly ones. I'll take a look at the shock bushings. Although converted to coilovers, those bushings may be originals.

Re: Wheel hop issues
I swapped my entire rear, less the batwing to super pro bushings. Much better than traditional rubber or polyurethane.

Re: Wheel hop issues
Just checked my build sheet... All bushings were replaced with Super Pro bushings, front and rear.

Re: Wheel hop issues
I asked artificial intelligence on Google for the heck of it.....
AI Overview +1 Wheel hop in a rear-wheel drive (RWD) car can be caused by a number of factors, including: Suspension damage: Suspension damage can be caused by hitting potholes or other road hazards, worn components, or loose wheel nuts. Tire issues: Tires that are underinflated, unevenly worn, or imbalanced can cause wheel hop. Axle twisting: Wheel hop occurs when the axle twists, or "winds up," and then the tire breaks loose and snaps back. This constant twisting and unwinding causes the tire to bounce. Power levels: If the tire can't handle the amount of power being applied, wheel hop can occur. Bushing deflection: Bushing deflection can cause wheel hop. Shocks: Using the wrong shocks can cause wheel hop. |
