I won't be doing racing, but DEFINATELY good to know. And if someone is willing to help id appreciate loacating a part number from summit or other source with everything needed to complete shaved handles. THAT WOULD BE VERY APPRECIATED. Reason being the kits i've found at summit don't say anything about door poppers or everything needed to accomplish that, and maybe I missed it in the description. With that said if any body guys or guys who have done it before can give part numbers and how well they worked for them. LIKE I SAID, I WANT TO THANK EVERYONE WHO RESPONDS.
