New Sports Sedans

[toranaracer]

Dean Randall had to cut his Larry Bar out at Phillip Island many years ago before they would allow him to compete!!
The cut was done and the car was allowed through scrutineering.
I cannot remember if it was before of after the infamous Tamasi incident?

Can I ask... What actually consists of a Larry bar???

[MrBoost]

other than cams, is anyone against larry bars?

what is cams problem with them? is there a safety issue or something?

i love them, stuff having a lowndes incident going up the hill at bathurst without one!

Toranaracer - Dean must have been pretty angry! I know i would have been. It's never fun cutting bars out of chassis's let alone at a race meet. The integrity of the chassis would surely be compromised.

MrBoost - i couldn't agree more... the quest for speed aside, Lowndes's incident highlighted the safety aspect. Without it Lowndesy may not have been walking away from it.

Awesome Phil looking good, what paint scheme have you decided to go with????

[Corolla52]

I have a new car starting to be built so I would like to know if the Larry Bar is legal.

Whats the plans stefan?????, what are you building??, what running gear...

[quote]I do not want to become a scrutineer that is why the Kerrick series and the whole sports sedan movement Australia wide needs to have a fair dinkum tech officer funded by a per member levy across the 5 known sports sedan clubs. The series will employ that person for National rounds but we are not the only one that should be kicking the tin.

The only thing with regard to roll bars that has not been mentioned nor discussed is having one certified by an engineer. I am not the full bottle on this yet however I think if you design or have designed a cage by an engineer that is certified by an engineer then CAMS may accept this. For instance you can build a cage with crome moly (I think) if it comes with an engineers certificate.

Maybe Kerry had the cage in the Aston engineer certified????

So if anyone wants to do something not as per the CAMS ROPS rules maybe the answer is have it engineered and submit to CAMS. As for the cost......I doubt that you would see much change from $5,000 given the liability the engineer has to wear and the cost of his/her professional indemmnity insurance.

Phil, so if they are an “Engineer Certified” chassis, shouldn’t a quick call to CAMS to verify that both the BMW and the ASTON are certified. That would go a long way to put a few people’s minds at rest knowing that if they too want to spend the 5000.00 odd dollars to get the right to have a Larry bar.

Schedule J:
14.3 Alternative Designs: A safety cage structure not in compliance with Schedule J specifications may be
approved through the CAMS certification process. The static load tests detailed in FIA Appendix J, Article 277
shall apply. Approval in principle for any proposed design shall be sought from CAMS prior to commencement
of construction.

Whether this relates only to "14. Specifications - Single Seat Cars" needs to be clarified.

The way I read it, there is a minimum standard "Schedule J" that is there for someone to follow if they choose to build a car. If however you choose to deviate from the minimum standard, there is a process to be followed to ensure any additions to the minimum standard comply with CAMS requirements.

Perhaps Kerry has followed due process and made application through the correct channels. I don't know this, because I haven't asked him. I would suggest that a guy who has been engineering and racing Sports Sedans for as long as he has is probably smarter than most and knows what he wants in a car.

Regardless, your idea is a good one Abuilder! Let us know what CAMS have to say when you speak to them and ask them the question.

As a side issue, the two fastest cars in the country don't run a Larry Bar! Whilst I personally see merit in the safety/structural benefits of a Larry Bar, it's not the lack of one that is preventing most from getting within 5 seconds per lap of those guys.......

Schedule J
6. CERTIFICATION BY CAMS

"6.1 A certified safety cage structure is one which has been approved by CAMS for a specific vehicle,
notwithstanding that it may not comply in all respects with the specifications of this Schedule.

Important Note: The certification process does not provide for ‘free design’ safety cage structures. It is intended
primarily to prove that the manufacturer has met the strength criteria through engineering calculation
despite the use of material to alternate specifications. A safety cage structure must still comply with the
design criteria detailed in the applicable regulations to be eligible for certification by CAMS."
