I would say the Ek Chassis is very good, and with mods can be a very capable car. A Ek9 will allways woop a EK4 out of the box. EG nice and light, and DC2 again out of the box very capable if it's better than a sorted EK i think that is personal preference. Whatever chassis can be made better wit the right mods, and i allways say start with the safety related components first, Brakes and suspension, bushes and correct alignment. Lots of people run far to high spring rates and spoil such a good car.
