I have the BMR lockout kit and there is 0 NVH . I too am very picky about noise and vibration. I did all the polyurethane bushings in my other challenger and i hated it on the street .. I tried the 3.09's with the 305 tire and all I did was over power the tires . I switched back to the 2.62's and it was much better with the 305 tire . The 305 is 28 inches tall .. the 315 is 29.4 inches tall .
Also i went with the ARP 1/2 longer wheel studs . I did buy new titanium wheel nuts ... Less rotating mass ... Hey every little bit helps lol .. The tip of wheel stud is level with the edge of the wheel nut . I will post a pic later .
@Speedy! With the 315's you can add power back into the launch because of the increased traction.. Just swapping tires will slow down your 60 foot with no other changes ..
