I run 6 kg/mm front and 5 rear (tien flex) and like them quite a bit. They're firm but not harsh on the street. If you think you'll track it a lot I'd go 8/6. 10/8 is starting to get into dedicated toy territory.
Multiply by 55.9 if you want lb/in rate comparisons.

Well I'll tell you about my setup, I use it for track days and daily driving and I'm quite happy with it and would definetely reccomend it to others for that sort of use. I've got Tein Flex's with 7kg/mm front and 5kg/mm rear springs (it comes with 6 and 5, I bought extra fronts). Those rates work out to be about 390lb/in and 280lb/in. I've got a Racing Beat front swaybar and stock rear swaybar. With 225/50/15 R comp tires all around on 15x8's it handles quite neutrally with NA power. I honestly don't think there's any reason to go stiffer at this point (it's plenty stiff), it'll make street driving worse and probably won't make it any faster on track. I do have a front strut tower brace, a lower arm brace in the front and a roll bar to stiffen the car.
Your spring rates, sway bars and/or wheel and tire selection will likely need to be different to deal with the extra power, but there's a baseline setup for you. For reference, 400lb/in front and 275lb/in rear springs is a very, very common setup for NA FC race cars.

For me, I looked at what the racers were using, and read reviews from street users and picked what I figured was a good compromize. The 7/5 springs are the closest metric ones to the 400/275 that so many people use.
As for ride heights, in some ways lower is better, but you'll have issues with speed bumps, driveways, bumpsteer, increased roll couple and so on. Personally, I set my car up so that it's lowered, but still at a reasonable height, so that it doesn't scrape, doesn't rub and doesn't look dumb.
