Koni FSD struts and shocks

Model: Carrera 4, Year:1994, Mileage:85000, Type of use:Both Street & Track
Do you have any experience with Koni FSD struts? They sound great, good ride with good response. I do several DEs a year, but still want a comfortable ride on the street. I am not lowering the car. Should I also have the rubber suspension bushings changed since the car is 20 years old? If not FSDs, then what would you recommend? Thanks.
