Question In Regards To Door Trims

[phunky_monkey]

Hey guys, just wanted confirmation on something. I've been told that to pass scrutineering I have to run some sort of door trim, it can't just be bare like the picture attached.

Is that right, or can I run without them?

Cheers

would depend purely on the specific category regulations... i can't find a general rule in the manual.

i'm swiss cheesing the doors on the rx7, but covering with some c/f sheet cause i reckon it looks a bit ugly and unfinished.

It's only used for club sprints, but someone mentioned that there may be an issue to to being able to injure yourself on it in an accident. Just wanted to be sure as I need to get the cage made around my standard trims, or whether I can get them running closer to the doors without trim.

an overzealous scrutineer might take issue, but there would be no regulatory basis to their concern… particularly if you have a cage with side intrusion bars

I got pinged for not having door trim and the possible injury hazard at last years Autralian Hillclimb Championships. I had to make a temporary door card out of cardboard and re-present to scrutineering. They were only concerned about the drivers door.

You are allowed to cut/modify the door cards and interior trim to clear roll cage members.

Aluminium sheet is easy, cheap & light. You can get whatever guage you want (eg 0.8mm, 1.2mm, 1.6mm) from most industrical insulation businesses. It is easy to bend about and doesn't weigh very much at all.

wouldn't surprise me, what was the basis of the claim or charge?

what are they trying to achieve... I mean its not going to stop anything coming through the door and if they are genuinely concerned about your arms why isn't a window net not a requirement!

Regardless of any ruling, I would still prefer to have some form of door card. Accidents can be very violent things and arms flailing around could become quite a mess coming into contact with sharp metal edges. It's something I've always been rather paranoid about. That and knees smashing into intrusion bars.

My 2 cents..

[t01-100]

Yeah same Ben, but scrutineers applying rules that they believe should be in place, but aren’t documented really shit me.

To make mine doors look neat and tidy I'm doing similar to this, but in carbon....

[hrd-hr30]

that basically covers what they were concerned about. I had been meaning to get to it anyway purely from an aesthetics point of veiw.

There are regs that mandate this even in Sport Sedans:

3.7(ii) When front door trim is removed, it must be replaced with a flush-fitting rigid material, save that local modifications are permitted to facilitate fitment of roll over bar and anti-intrusion bars.

Nizpro 200SXR door trims would have to be the coolest ever made...

I'd hate to think how much time went into them as they are flawless.

Take a look at your doors... If those doors cop a hit those thin metal sections joining your "speedholes" are liable to snap, point towards your body and attack.

Flat sheet aluminium door cards covered in lightweight carpet will make the car look nicer and that tiiiiiiiiiny bit safer

I hear you, but we'll if we were really serious about our doors turning against us surely a panel of aluminium honeycomb laminated with kevlar/cf would be the answer instead of shag pile!!

[phunky_monkey]

Hey Merli, that's not my door it's just an example but I see what you mean. My door hasn't been swiss cheesed like that, but I'm probably better off just going the door cards, or keeping my stock trims.

I think the aluminum sheet covered in thin carpet is the best option, the example on the Donut king GT-R turned out very neat, and the one posted by Stuart is very neat also.

Thanks for the advice guys, much appreciated

hehehe.. Where do we stop? Probably when our wallets are empty

That said, I'm not sure that a cf/ck weave would be the best choice, as they both "shatter" and send armies of little shards to attack you instead of just bending on impact...

[t01-100]

the doors usually leave the car on the second time over if your have a real crack anyway!

Possum Bourne Motorsport does the most exquisit carbon door cards I've seen to suit their cages..... can't find a pic right now. A matye bought an '07 spec C from Sti recently and the door trims are V droolworthy

Ahhhh, to have silly amounts of money to spend on cars...I need a payrise stat

[Marlin]

Ahhhh yes... that's the one

[phunky_monkey]

That is pure car pornography!

Well, cage is booked for 3 weeks away, so I've got a bit of time to get off my arse and knock something up. If only I wasn't useless with my hands!
