only reason i put a 5 point in my car, before i totaled it, was because i do alot of spirited driving. if youre not getting it either sideways or throwing it around corners hard, then dont bother.
pretty much, leave it stock until you can cage it.

peace

i do want bring my car to track. but not yet.... im just trying to build it up slowly....

Then leave the harness out until you get it built. Not only will it not be safe without all that additional bracing, but all that additional bracing causes a problem too. Being in a car with a cage is dangerous, too...since that is meant to be used while wearing a helmet. No amount of padding is going to make that bar feel any less like a baseball bat in a crash.

Not to mention the fact that you'll look like a tool driving around town with a roll cage and 6 point harness in a stock NA FC

You don't need to modify anything to get on track. What is needed is to make sure that it's in proper working order, replace all the worn out bits, make sure it's not leaking and make sure it'll be reliable. Some reliability mods, like a bigger rad and so on are a good idea. In fact most instructors would rather that you show up in a more stock, slower car at first, as there's less chance for a big oops, and it won't mask your mistakes like a high HP, high grip car can. You'll probably learn more too.

The best way to make the car faster is to improve the driver, then every car you ever get into after that will be faster too. It's a lasting, transferrable "mod".

I partly agree on the roll bar/cage thing, in that you don't want to drive a caged car around, but I think a roll bar is ok. Besides, the whole car is made of metal, and there's lots of other things you can bash your head on easily enough, a padded roll bar isn't going to be much/any more dangerous.

dont be stupid, you need a cage. why the fuck are FC owners so cheap?

you can build a good 12 point for under $300 if you got the skill.

call nukabe 1888-591-6277 they have ok prices for per made direct bolt in cages that fit with all the stock interior.

If you're racing, then yes, you need a cage among other things, but if you're just doing recreational lapping and driving schools then you don't need any extra safety gear, and a cage may even cause more harm than it saves, as you can easily hit your head on it in an accident, unless you drive around on the street with a helmet.

proper seat+properly mounted harness= you ass isn't moving up or down, front, backs, LEFT , RIGHT

hence its safe to sport the cage daily as long as you keep the belt on.

The issue is that harnesses are not DOT legal (i.e. illegal to use them on public streets). That doesn't mean people don't do it, but they aren't legal none the less. So using a "stock seat belt" and a cage could be hazardous on public streets (if you are trying to stay legal).
