10 mm spacers on the front (hub centric please) will help and is cheap and easy. (widen the track which also gives more - camber) The best thing to do is learn how to drive a car that oversteers. If you fight it, you will stay slow, accept that it pushes and learn how to go fast with that condition. You know what I mean, like learning to drive a FWD. You must do certain things to be fast. One thing that works for me is lightly braking into the corners to add weight to the front and inducing more grip. If you are too hard on the brakes you will just go straight so practice is necessary but it works. The other way is brake early and be on the gas throughout the entire corner. Again it takes practice and works better on slower corners, but you can steer with the throttle by making the back slip more than the front. Drift technique if you like ..... again it's easy to get it wrong. I imagine the real experts do both. Trail brake and throttle steer. I've done it right before and blown it before. Practice is key. On a side note, any Miata will outbrake you because of their light weight. They are as fast as anybody in the corners with decent rubber. The best you can hope for is to be nearly as fast and pull 20 lengths on the straights. There are other things you can do but it's better to learn how to go fast with what you have first. It will make you that much faster when you improve the car ........ I made mine worse before making it better, be careful what you change.
