I have driven my car with caltracs on the street and stock springs for the past 3 years, and this year upgraded to the mono's. With both springs I drive on the street with the bars setup just how they are at the track (0 preload,bars just touching) and no issues. I will say the ride has gotten stiffer with the mono's, but I didn't build the car to be a cadillac on the street.

I'd say you'd be fine
