We recommend our progressive y0452/02. for these shocks. On FG cars the OEM springs can be used as well. Shock versions y1137/07 and y1137/08 for Smartech C5 and FG on-road cars should use spring Shock oil recommendations:The GPM-Spezial Cross shocks are factory filled with 1000 viscosity silicone oil. This gives a very good shock performance at normal ambient temperatures.When a softer shock is required, you can go for 500 or even 600 viscosity oil; 1500 and up if you prefer more damping.One 50 ml bottle fills 5 long or 6 short shocks.For use in a Kyosho Scorpion XXL (version 6), the shocks must be installed with an additional 4 mm spacer at the lower front mount (see picture above). The stock Scorpion springs can be used. We suggest silicone oil with a 100 to 200 viscosity for the front and a 200 to 300 viscosity for the rear .
