As long as you haven\'t cut weight out of the doors it\'s fine. The cars are really strong structurally. The doors are part of that structure, but when you cut them down or change them for light weight ones you need a cage in there with door bars.

You could install a roll hoop for added bit of support and satisfaction that its there

UNless you\'ve disconnected the brakes and the steering you\'ll be as safe as you ever were.

I didn\'t cut out anything inside all I did is take all the trims and door panels,  back seat speakers ,seat belt,and put light seats ,light battery ,remove a/c and,fibre glass body kit all round.and that\'s it pretty much...
So I should be fine is that right ?

That will be fine, are you going to doing track days?

I would think about a cage in the near future as the better you get the faster you get. And a roll cage is the best thing to have. It also means you can have a proper harness set in the car

Yes it is legal. I don\'t think there are any regulations for MOTs that say you can\'t. The harnesses have to be fixed correctly though, as they are the same as a seat belt

You do need to consider your mounting points when using harnesses. Take a look at this:

Most harness manufacturers will also give instructions on secure mounting points and the best angles, so it\'s worth going and reading up.
