Erick – Last time I checked Kings had some F30’s in stock. If they don’t, 132slotcar.us has them in stock.
Chassis – I don’t know if your new car comes with the adjustable chassis but if it does not it is well worth the $10 to get one. The other thing you would want to do is “bake” the chassis to make it as flat as possible. I can do it for you if you are not set up for it.
Looking forward to running with you.
