The stock pistons in the 1/8 CR front shocks are 1.4mm holes. Try the 1.5mm hole pistons and 30 or 35 wt oil. The rear will work much better and cut down on the bouncing.
What 3S lipo are you using? Do you know the weight of it? I'm going to the same MM, Medusa 50mm 3300, and Rhino 3S 4000 lipo for my RCM chassis CRT.5.
