i dont have the f13, but am running the f10 and im using the PRC gold kit. i think the f13 uses a .603 on the exhaust side and i wanna say a 59x on the intake, but the springs can handle it with ease.

You can use the 918's, but if your looking for safety then I would run duals. I'm running comp duals that Candy sold me when I bought the F13 from them last summer.

I have a set of PRC Platinums waiting to get installed with my F13. They have a bit higher seat pressure than the Golds and cost pretty much the same. Picked mine up from Futral.
