Re: Drag Radials Sizes and capabilities.
If your suspension is setup right you should be able to dead hook and run mid 12's. Years ago my car ran mid 12's at 109 on the motor and dead hooked with BFG drag radials. My suspension mods consisted of removing the swaybars, Comp 3 way shocks up front and some home made clamps on the front half of the leaf springs.
What have you done to your suspension? Do you have swaybars?
