When running dirt would it be wise to bolt the front frame section right up or use solid bushings such as poly urothane?

Most guys around here take them off and set the body right on top of fram. I have race cars with factory rubber mounts under the body to frame and with out. In my opion with them out u get a better feel of the track.And the only reason they are used is to take noise and vibrations away.

In the interest of chassis stiffness, you need to have the body solid mounted. On my metric frame I-stock I leave out the rubber bushings and replace them with 6" long pieces of 1 1/2" square tubing. They are welded to the frame and the floorpan. This raises the body back to its original height. Raising the body allows me to move it about an inch to the rear. More rear weight is good. It shifts only about ten pounds but it is free rear weight. With a Camaro type front clip everything should be solid as possible to the body.

Thanks for the compliment, Eddie. With a camaro subframe as with a nova by all means weld everything solid. Replacing a rubber bushing with steel would maintain body height and alignment. But any way you can solid mount it the better. You don't want the cage mounted to the body with the front support rails and reinforcing welded to the front clip with flexible clip to body mounting.
