My experience falls in line with most here. The radials either hook or spin hard. My Dart was quicker and faster with the radials than it was with new slicks, 275/60 MT ET Streets and new 28 X 9 MT slicks.

I haven't tried slicks with the 408, it has gone 1.38 60' on pump 93 with no power adders on a 325/50 MT ET Street Radial. Over the winter I plan on buying a extra set of rear wheels and a new pair of slicks. There is only one track here that it will consistently hook at with the radials. I bracket race so it will run on slicks next year.
