Hi all,
In the roadgoing classes there is a rule that the car:
'must compete in a road legal condition'
Three questions:
1) Front numberplates: lots of people remove or change them. Perhaps this is to use the mounting holes for their timing strut, or to protect the identity of the car (common on trackdays) - should this be something that gets you in trouble with a scrutineer?
2) Say you run with a front numberplate on a pre 2001 car. If the car has passed MOTs with this numberplate for many years and it is clear and legiable - although perhaps not quite the regulation size, does anyone care and again should it get you in trouble with the scrutineers?
2) How on earth can a car be road legal when it has a metal timing strut fixed to the front? I have even been told that the timing strut shouldn't obscure the front numberplate! Doesnt this make any arguing over non performance enhancing things like number plates irrelevant?

There is a huge amount of freedom in Mod Prod, it's not a free for all, but there is an awful lot that you can do.
Drilling holes etc in the bumpers is one of those things. |

I found an example of a typical bumper modification in the latest speedscene. As this car runs in mod prod I assume this type of modification is legal in mod prod? What about roadgoing?

I think convincing a scrute that vents in the bumper constitute an aerodynamic modification might be a bit of a hard sell. |

The blue book states that production cars can have aerodynamic devices provided that they don't alter the silhouette. I can't see that your vents alter the silhouette.

Can anyone help with my bumper modification questions please?
Thanks,

11.2. Cars must compete in an event in a road legal
condition.
10.9. Timing Struts – Where timing is activated by a
light beam, the vehicles will be fitted at the front with a
vertical timing strut, minimum vertical height 254mm,
the bottom of which shall be not less than 180mm and
no more than 200mm from the ground. The strut will be
in matt black on both sides, over its total area, which
shall be not less than 254mm by 51mm. No other, or
further forward, part of the vehicle may interrupt these
dimensions or actuate the timing.
In my opinion 10.9 and 11.2 are mutually exclusive. Nowhere does it state an exemption to 11.2 for a timing strut.

I think that you will find that the requirement to fit a timing strut &/or race numbers is in addition to the car being in "road legal condition".
As for nit-picking may I suggest your comments fall into this category!

This is an excellent point, and one I would like to see a response from the MSA on. |

Is your car an Import, if it is, its allowed to run smaller front plates by law. I think the characters are 64mm instead of 79mm high. If in the picture the front bumper is the stock one, then the number plate cutout is designed for the jap plate sizes.
The other method , bit excessive tho', is get a cheaper private reg with only one number in, the plate can then be legally narrower.
The front bumper including number plate recess is original, the two small vents were cut in. My car was originally a UK car - I believe they just bolted a big black metal number plate holder over the existing recess for the UK market, which I don't have (lots of owners remove them as they damage the front bumper over time). |

My problem is that a legal plate blocks the two vents to the intercooler / radiators which you can see in the picture. The existing plate fits into the original recess in the bumper (i.e. the plate is the size it would have been if the car was in Japan). I suppose I could get an offset plate like you see on some Evo's.
On a related note can anyone clarify the rules with cutting holes in the front bumper in the Roadgoing / Mod prod classes? This was done on my car years ago and you see quite a lot of cars with the front bumper modified to improve air flow. Again, I was given a telling off for this by the scruitineer (roadgoing class).
The way I look at it, the existing vents are a small modification that hopefully help me keep the car vaguely competitive with the Evo's and Imprezza's (which come with a mass of openings in their front bumpers as standard). At the end of the day the rules should be encouraging a variety of cars to enter in the roadgoing classes - it makes it much more interesting than a Evo / Imprezza class.
For next year I am considering the move to mod prod and would need to improve airflow further if possible, so it would be good to understand what I can and can't do.
Thanks,
Adam |

Thanks Graham - dead chuffed!

I think you're right Adam but at the time I presented it as a roadgoing car so it needed to comply. I guess I could take the plates off altogether and have the logbook changed to re-classify it as modprod or whatever. I doubt your plate would even get you stopped by the police unless you'd really upset them. I would leave it as is and argue the case but as with Peter I might just have a legal plate in the boot just in case... |

I also got picked up by a scrut for the plastic bonnett mounted plate on my road legal MOT'd Marcos (as supplied by the factory in 1969)
I now carry a "Legal" metal plate to fit if a scrut has had a bad day
