BTW, all Caster kits will now come with a full set of fluids for the diffs and shocks, based on the recommended team setup.
For example, the ZX-1R will come with:
Diff fluid: 5000/7000/3000
Shock fluid: 50w/40w
Fluids are the new G-Force Certified brand, courtesy of Fusion Racing Products.
These are being included at no additional charge.
