the autopower cages & bars are not NHRA legal which means the design, type of bars, and thickness are not to their standards. as for general safety, i thnk it would help a lot. if you want one just for safety and/or looks and you plan to never break into the 11's at the track, the autopower would probably suit you and it would be about half the price of the real deal. you'd still have a pretty safe car and it will stiffen up the body a bit.
