Haha bro, i respect your suggestion but. First of all even if i cut my roof and go out without it, ride safety doesn't have to do anything.
I'm not cutting cross member, or frame.
And plus sunroof can't be installed by just cutting a hole. This roof has dual layer roof since it's a folding sunroof.
And the method I've done is the safest and yet proper way to install a sunroof. Take it to 250 or 300kph this doesn't have anything to do with ride safety. Plus cars body is made up of 19-21 gauge metal and metal is joined by gas weld spots.
So this has been installed by proper gas welding.
