Seattle, stop in at Seattle Indoor Raceway.
Our mini class is growing. We have many of the hop ups for the car. There are 2 national mini champions that race there. And they can help you with set up and tunning.
What kit did you get?
Are you going to be racing it or is it a toy?
I would suggest the Teflon sealled bearings. Tamiya has good ones I know there are others too.
The shocks you have listed are a great starting point. The other option is any of the Tamiya aluminum threaded body shocks.
Toe in rear uprights are run on most of the cars.
The other hop up I feel is critical, is the aluminum front knuckles. on the M03 the plastic ones seem to bend pretty easy.
the other must is good tires. I run a TCS rules car, so I have only used the Tamiya tires. the Type A tire works well.
as for other hop ups. a spring set is a must. Older tuned spring set should work i think it is a 53334
there are sway bars, carbon gear shafts, aluminum king pins, Stainless suspension shafts, universal drive shafts, heat sink, titanium screws, titanium turnbuckles, a ball diff. all these in no particular order of importance.
