I think I want fully adjustable struts and a for sure a drop spring that rides ok but I will sacrifice ride for launch. I was thinking koni yellows and H&R race springs (2.2" front 2" rear) nut any better suggestions?

My car is a CRX.

Now does anyone know the difference between koni and tokico's

Also does anyone know how hard it is to change out the bushings to insert the energy suspension kit? Is it better to have someone do it? What tools do I need.

I really will never autocross, I drive the car everyday, and take it on the track on occasion to see what it runs in the quarter.

thanks ahead...
