Slapper Bars are like the Caltracs & Datsun Comp setup, except the front is not solidly mounted to the chassis. It doesn't interfere with normal suspension unless wind-up occurs. Plus it has a little "play" so that it hits, it slaps, bites down to help traction.

Not difficult to make yourself: 1-3/4" square tubing, Hyundai H100 tray stops. Custom U-Clamps. Double nuts or locknuts on all u-clamps for extra security. These had a big difference at the rear when launching and take off!
