I might weld it as well...thing is if it was up to me I wouldn't fit a cage at all!... I don't plan on crashing; and it just weighs the car down!

I have been to 19 drift days with no cage and have not really seen the need for one...and before people think "they are just slow practices around an open field", these included twinning,80mph entry,solid concrete barriers and parked wagon trailers...
