Well, your brave, I'll give you that. They are not to my taste personally, but its your car, if you like them, then sod what other people think, just enjoy it.
With regard to the danger aspect, you say you've already got points on your license, well be prepared for more as your speedo reading is gonna be well off.
The other thing is handling, you say it feels stock, nope, not buying it. If you provoke the car its going to bite your head off at the first opportunity, think about it, if your standing up and someone pushes you, you'll regain balance quite easily, try the same experiment while your on stilts and see if the results differ.
One last bit of advice, there is a reason the car has wider tyres on the back, 1) To provide more traction on acceleration
2) To promote underteer, in the wet, your car is going to be spinning round on the spot like its on ice.
Good luck with it though matey.
