Well now, I'm not 100% convinced of that. I installed 325/50-15 DRs on my 367 powered Barracuda with just HD shocks, and a snubber, and I think they 60ft no better than my Cooper 295s. I have not tested by timer, but they spin just like the 295s and don't stop spinning until I back off at 65MPH.
Ima thinking,on the street,that healthy sounding 440 is gonna annihilate anything he can fit back there.
