I've set rise and fall edge to 20n and set the simulation timestep to 100n a then 10n. Still not ringing.
Sorry, but i don't understand your last sentence...
Each inductor you added forms a series resonant network with the relevant stray capacitance of the MOSFET, but also in series with those resonant networks are resistors which dampen the ringing. That is to say, as the damping resistance in a series resonant network increases, the amplitude of the ringing, and the time it takes to decay completely, decreases*. In the case of the BSP89 MOSFET you picked, the .model directive shows it has a gate-to-source capacitance (Cgs) of 70pF and a drain-to-source capacitance (confusing referred to as Cjo) of 10pF. The characteristic impedance is determined from the formula (L/C)^0.5 which comes out to around 12 Ohms for the gate LC network, but the series resistance is 50 Ohms, so this LC network is definitely overdamped (in fact, with such small LC components I doubt you'll see ringing even if the gate resistor was reduced to 1 Ohm).
I'll leave determining the drain and source node characteristic impedances to you as an exercise, but note that ringing at these nodes really only occurs during turn-off, not during turn-on (for another exercise, try to figure out why).
* - and for a parallel resonant network the damping resistance is in parallel, with ringing amplitude decreasing as resistance is decreased, so the inverse of the series LC network.
