I am running Kyosho springs. White in front and gold in rear with Losi cups and the traxxas collars. I was a big improvement over the stock setup. I then put my Durango dex210 shocks on and the car was dialed. I am going to order another set of front shock bodies from durango to put in rear to correct the droop. This buggy is going to be so good when AE comes out with the Big Bores!
