Is the front reinforcement bumper a Raodworthy item or it can be removed?
how many people here have them removed?
Its the black reinforcement bar behind your plastic front bumper.

Assuming you mean the part under the piece of foam in the picture?

I'd guess so in that it wouldn't have been put there for no reason, but don't really have anything more than that.

Umm, I would imagine that it would be an ADR requirement.

I think in the case of a serious collision significant questions may be raised...
More opportunities have been lost from indecision, rather than wrong decision.

The beam is there to spead the impact load to the front panel and then chassis rails. On the NB models which was the 1st to have an airbag then it forms part of the whole structure and could be considered an intrinsic component.
In Australia until the introduction of ADR69 (Jan 01/96 for all new models) there was no front end accident test that would require the reo to conform however from then on it was needed. There are strict rules for any ADR69 affected vehicle with regard to modifications and any replacement bumper, airdam, radiator, etc could/may affect the way the OEM components do their job in an accident.
Would it be a roadworthy thing..... IMHO on a NB onwards, yes but the examiner would have to be aware of it and this could be unlikely unless they are an MX5 expert.
Im not sure what purpose not having the beam in there would solve?? Having had a few hits on the track I can assure you more damage is done without it than with it.......

your car is designed to progressively collapse in a serious prang.this is the first part for a front ender, this doesnt just spread the load a little.but collapses at a controlled rate(air out of the little holes) trying to decelerate you at a rate that may just keep you alive.Dan,you should put it back in,or,never prang.

I wouldn't worry too much about weight. :lol:

I removed mine too, not because it was heavy, just because i like to live dangerously.

Have put this back in and seems that the bodykit require some modification for this to be put back on. I think little protection is better than no protection.

I always keep this in my race cars cause you can give someone a pretty hard whack without damaging your car...the other car usually comes off much worse, espescialy Lotus'ssss, and the odd Porsche.
