Thinking about one from maddat...

Question is: Does an engineer need to install it? Does it require a engineers report? and how hard is it to put in?

more then one question then... :P

Talk to maddat.

If you are to be making any changes like the tunnel, chassis, brakes or anything of that nature check with you local engineer, or sumone witch has a FULL REPORT,

I did and thank god i did before cutting anything, the tunnel MUST overlap by 20mm all round and welded both sides top & underneath, i fab up a tunnel my self it passed ok
i must keep my heater controls in for dimmister the front screen,.........double check your self.

There has been a few body mods changes after there been rego'ed and when rego time comes around again they get ride of there car before hand to save on the engineers report, ......thats my opinon
