My car, 1968 Dodge Dart, is consistently running 11.50s in the 1/4 mile. It has Weld Wheel Draglites on it currently. 15X10 Rear and 15X6 Front.

If I switch to new direct fit Cragar SS Wheels (same wheel combo size as listed above), how bad will the weight of the Cragar wheels change my time in the 1/4 mile?

Thanks Moparts!
