I have the 60mm set-up, although opted for higher rated linear Eibach Springs, as Drummond couldn't supply the springs I wanted in time. As standard the tarmac kit for the EVO comes with double progressive springs, which are good for the road though.
The 50mm and 60mm are similar. The bigger the strut the more finely the damping is controlled, and the better the car handles. Riding kerbs on a track for example is so easy with these big struts - the car stays totally controlled. The 40m gold struts will be ok for street use. What is your application??
