At the track the best i could do is 2.134 in 60'. If i realy lay into the gas at the track or on the street i seem to get a lot of hop at the rear wheels. how can i stop this hop and get better traction

 

wheel hop...

1. As you accelerate the axle drives the axle tube towards the
front of the car.
2. The lca bushings are compressed until they meet the
resistance associated with the frame.

3. The axle tube then begins to rotate about the pivot point
represented by the lca bracket. This continues until the torque
arm provides sufficient resistance to inhibit further rotation.

4. At this point what happens is dependent on the the geometry
of the lca's relative to the rear end.

If the the frame mount point of the lca is still above the axle
mount, the tendency will be to try to drive the rear end under the
car. In a sense the tires will see an increase in loading

If the frame mount point of the lca is below the axle mount point
the tendency will be to decrease the loading of the tire. This will
result in a momentary loss of traction. This continues until the
rear spring finally reacts and pushes the rear end down
a bit. As soon as the tire regains traction this sequence starts over.

Sooo...
What can you do to deal with this...
1. Improve front to rear weight transfer
2. Improve lca geometry
3. Improve suspension components
4. Better tire selection

 

This winter I swapped a 2.73 open for a 3.23 posi and wound up with a good case of wheel-hop.

The LCA mount at the frame was lower than the axle mount. Last week I installed Spohn's LCA re-location brackets and the hole shot is much improved.
