MSA Rule News
We are grateful indeed to the World's most successful OMS Circuit Racing team (RGTEngineering Racing aka Gary & Chris Hill) for bringing the following post on the OMS website to our attention. The article appears verbatim apart from removal of a telephone number
Following communications between the MSA, National Clubs, Championship Co-ordinators and individual competitors, the following statement has been released today to all scrutineers. Many thanks to Clive Austin (an OMS Hillclimber) and the group of individuals who we know have lobbied on behalf of competitors to secure this clarification of the newly worded rule (J)5.2.1.

The following article has been published today in The MSA Scrutineers
Bulletin which should clarify the situation regarding hazards within the
drivers compartment .
There has been a slight re-wording of this regulation, with the words
“such as to prevent there being a hazard” added at the end
of the first paragraph. Section J applies to all categories of car, be
it a touring car, single-seat race car, sports racing car, cross country
vehicle or whatever. The first paragraph of (J)5.2.1 basically requires
that the vehicle occupant(s) be isolated from the “nasty bits”.
This is pretty straightforward in such as a touring car, for there is
generally a “box” with the engine and other “nasties”
and another “box” for the vehicle occupants. It is not quite
so well defined in such as a single-seat race car.
Typically, forward of the pedal box are the hydraulic cylinders, and while the “bulkhead” of the pedal box is unlikely to be fluid-tight, the reality is that the risk of fluid getting into the volume occupied by the driver’s legs or onto the pedals is very low. Again, time-proven and acceptable.
It is common for the suspension members to be mounted inside the body
skin, whether the skin is a removable panel or panelling riveted to the
chassis. The sketch plan below shows a typical arrangement where the pivots
are carried by vertical members in the chassis structure, the bodywork
being holed to enable the wishbones/suspension arms to pass through.
I hope this clarifies the situation and lays you and your competitors minds at rest. For the benefit of the scrutineers we have actually used the photos of your (OMS 2000M) front bulkhead as an example in the bulletin.
