Scrutiny requirements for seats and rollcage HELP

[Markgt3]

Need a bit of info before the weekend regarding a Porsche 924 that we are racing this weekend in Snetterton in a club event under MSA regs

The car was built in the UK for the 924 championship and passed scrutiny last year in Ireland but the seat is about 8 years old belts are in date but not sure will the seat pass scrutiny in the uk

Another question i have is the cage as its a bolt in rollcentre cage with cert and the foot plates of the front legs are bolted to the reinforcement plates (alu checker )and bolted through the floor and i am wondering if this is ok The main hoop foot plate reinforcment plates are welded to the chassis

The car last raced in the UK in 2007 and passed scrutiny

Any help greatly appreciated

Sounds like you're fine to me mate! Belts need to be in-date, seats don't - just securely mounted. I'm on my phone so can't see the pics, but the cage to me sounds ok - a little known part of the Blue Book states that if the engine is less than 2000cc, you only need a rear cage with diagonal, so with the car having more than the minimum I think you'll be fine. Take a copy of the Blue Book to argue the point though, I have seen scrutineers try to fail cars for only having a rear cage...

Despite sub 2 litre cars only needing a rear cage if a front has been fitted then it must be in accordance with blue book rules – this means a reinforcement plate on your floor , extract from blue book section K below:

1.3.2. Mounting of Rollcages to the Bodyshell.
Minimum mountings are:
1 for each leg of the main or lateral rollbar.
1 for each leg of the front rollbar.
1 for each backstay (see 1.2.3).
Each mounting foot of the front, main and lateral
rollbars must include a reinforcement plate of a
material of at least the same thickness as the wall of
the tube to which it is being welded (minimum 3mm).
Each mounting foot must be attached by at least three
bolts, minimum M8 150 grade 8.8, on a steel
reinforcement plate at least 3mm thick and of at least
120cm2 area which is welded to the bodyshell (see
drawings K13 to K18). The mounting feet may
alternatively be welded direct to the reinforcement
plate.

Without seeing the car it's impossible to say whether it will pass or not.

Scrutineers are only human, they will miss things/they may let some things pass, or they may not.

For example - I have a 6 point harness but used to only have 4 points of contact with the floor. I got past scrutineering a few times before it got noticed.

If your car looks tidy then most scrutineers want to see you race and will do their best to accomodate you.

Very Wrong, if there is a chance it will be used then it must be fitted to the rules. A non-conforming front hoop could end up in the drivers lap in a roll as it punches through the floor.

Very true.
Scuts are not there to stop you racing they are there to make sure you are safe, not only for your sake but others.

We have had scuts give us stuff to make the car pass.

But I wonder why there is such a difference in their opinion on what is right and what is not.
One will pass one will not.
IMHO there needs to be more consistency.

Scrutineers bulletin dated August 2008, page 3, paragaph title "Mandatory" applies here. You will need to be logged in the the MSA website to access it. I'm not quoting it as it's a pdf and I can't copy and paste from it, but in summary, non-mandatory safety equipment does not need to comply with the blue book requirements (the example used is an aluminium roll cage when no ROPS is required), provided it does not in itself create a hazard by its fitment.
