I bought a pair of SLK chrome bars...saw some installed @ the Dragon, they looked good and the increased diameter had added a little height over our stock bars...but I don't think this means anything to NHRA tracks, just the club tracks, which you would figure to be just the opposite...more of a chance of a roll over taking curves than going straight...crazy rules for stock cars...I will tried to raise them just a little, and you will need to change how they bolt up...a little welding, but won't be seen from where they bolt up...
