I think my car may be suffering from this but not sure exactly what wheel hop feels like.
I own a 91' Camaro the front end is pretty tight poly bushings in place of rubber and Bilstein struts and a poly tranny mount. I have yet to do anything to the rear. Only thing not stock is the KYB shocks.

What does Wheel Hop feel like and what does it cause your car to do??

this only really happens if you have a engine with alot of torque, when you nail the gas and spin the tires the axle will start to bounce up and down and be a big wham! wham! wham! and it feels like a eathquake inside the car.

 

would products designed to control wheel hop in high powered cars also benifit those that don't produce that much. I have a 91' Camaro 305 TBI

 

It doesn't take much torque to wheel hop. Sonoma's with 2.2L 120 ft lbs of torque will wheel hop. If you can spin the tires, you have the potential to wheel hop.

my will only wheel hop if i am in reverse and floored it.

 

The best thing to prevent wheel hop on a third gen is LCA relocation brackets.

Wheel hop is when the diff rotates during accereration. Because of how the suspension is set up, after it rotates up as far as it can go, the suspension stops and gets forced back down. When this happens the movement is then transmitted to the tires and they'll be forced up off the ground. It's this rotating of the suspension that causes wheel hop.

In a leaf spring car the springs will actually bend in an S-shape. Putting on ladder bars stopped or reduced the amount of rotation which reduced or eliminated wheel hop.

In a third gen with coil springs there's no way to do this. The rotational forces push the lower control arms forward. If the front of the LCA are level or lower than the rear mounts then the forces are being pushed in the wrong way. By using LCA relocation brackets the forces are being pushed up into the weight of the car and wheel hop is reduced or eliminated.

As a side note, my car produces a lot of torque and the passenger side front LCA mount is being pushed up into the car. You can see the floorboards starting to buckle. The problem will be eliminated this winter when I switch over to ladder bars.

Are LCA relocation brackets only designed to eliminate wheel hop or should they also be used when lowering a car? If used on a lowered car is it recommended to use them on any change in height from stock? I plan on lowering mine 1".

Mark

 

Lowering a car makes the factory locations go from bad to worse. The relocation brackets help correct the bad angles.

A good set of brackets will have different holes for adjustments. You usually want the LCA's parallel to the ground but they work better when the rear is lower than the front.

 

can you recommend a good manufacurer for relocation brackets? I was considering Spohn

 

ok.... this fits here i guess... Wonderbar... is that the bar that runs between the rear end and the tranny???
if so, i have one on my 92 rs... if not, then what is this bar... and is it stock
and what does it do...

 

The wonder bar braces the steering box area in the front of the car, it runs between the sway bar mounts (front).

The bar you are asking about is the torque arm.

I have an 89 Firebird thats only got a 2.8 and 5 speed. It had wheel hop too if it started to spin too much and now that I'm getting a 3.4 I'm worried about it even more. Are ladder bars the answer and easier way to fix this? Because I know I found some in Summit.
Any input is thanked.

I'll never recommend ladder bars for a street car. You'll hate the ride and they're not a simple bolt-in device. Ladder bars are designed for a strip only car.

Buy some good aftermarket lower control arms and relocation brackets, panhard bar, torque arm and sub frame connectors.

There are many suppliers for each but the Spohn products are a good choice.

 

Can a noticable difference in handling be felt after installing a wonderbar? Who is a good choice for purchasing one? I notice that Spohn does not offer these.
