This is either a hoax or a shameless plug for this company, as what fool would do this to their car.
also you will drastically put up your so called cheap 1.4 insurance doing these mods, but then I bet you haven't told your insurance company?
if you have fair play, but then you would need modified car insurance. if you haven't told them and you have an accident, your insurance will be instantly invalid and you will be personally liable.
food for thought.
