i use to have koni yellows with peddars springs i still do it there in the garage.. (if anyone wants them for $$$) lol, but when u say coilovers are harsh on the street, i dont really think so.. i have N+'s and there great and comfortable, handle very nice and i can lower the car when i want with out it being a struggle lol, so i dunno, i think u can have both IMO guess it all depends on the quality of the coil over and whether there damper adjustable..

but u are right about the koni yellow's
