Yes, i put a ton of street miles on 340Ricks challenger this past summer (i think i put more miles on his car than he did in the past 10 years ) with my setup on it and the same coil overs with #250 springs
the lighter spring seems to work well with me adding more per load to them for better reaction from the suspension.
