Using the smallest axle diameter allowable (based on HP) you will encourage both left & right axles to wrap-up at virtually the same rate. To increase forward bite you can raise the upper bars on both sides of the car next to the frame.

The difference is in the grip factor and mostly deals with the level of moisture present in the first inch or two of the surface material.

Make sure your car is correct for front geometry issues. Forward bite is slightly reduced to a degree (from Option #1), but the axle diameters here still remain much thinner than standard axles sold which will allow for axle wrap-up and increased forward bite over any standard diameter axles. %%EOF

BRB1. The driver can drive straight into the corner, brake harder, and get back into the throttle sooner than at any other time of the day. The idea here is to use the added compression on the left rear to hold that corner up and the rebound on the right front to force that right-front tire down and help increase traction on the front of the car.
