Title: Flush fit bonnet pins
Post by: NeilM on June 15, 2009, 05:10:56 pm
I've had the carbon bonnet a while now and love it but have noticed it lifts slightly at one corner due to the strut being to strong, this wouldn't normally be a problem but at Bedford Autodrome on the straight at 135mph a few weeks ago I thought it might go from a carbon bonnet to a carbon windscreen!!

To put my mind a ease I've fitted some AeroCatch flush bonnet pins (www.AeroCatch.com)

Firstly painted them Candy White and replaced black fixings with Stainless Steel.

Piece of cake, although I was a carpenter for 20 years, whether its Carbon Fiber or Wood the principles are still the same: measure twice cut once, always blame the tools, never be more than an arms reach from tea, Allow Darlin on your way to a photo shoot?, etc etc.

Your CF bonnet must be an OSIR (vent is the giveaway) - Same as mine.

Hmmm, if I experience even the slightest hint of bonnet lift on the German autobahns, I'll be using it as an excuse to do this uber cool looking (but safety precaution) mod.

You've done a superb professional job, Neil :happy2: 8) :happy2:

looked at that but the other side is tight down, tried adjusting the rubber stops but it was still a bit high and when the wind got under it it just got worse.

+1. I'd have to have a replacement bonnet on standby before I'd even think of doing this mod.

Just outta curiosity, does bonnet lift occur on oem hoods and how fast to you have to be travelling for it to occur?
Title: Re: Flush fit bonnet pins

it has happened in the past, but in minute cases in terms of how many golfs on the road. i dont think you need to worry about it!

....I didn't like the 'stepped' grill in pics but after seeing it in the flesh I now think it looks great and particularly suits the black & white colour scheme of Neil's car. It possibly also helps scoop more air being flat-on.

Cutting into carbon isn't anything like as difficult as you think. You just have to plan it carefully and take your time.

Having said that, I expect it'll be a case of VWR doing mine while I watch as usual.

My mate has them done on his car... hes carbon fibre wrapped them too  :love:


....Doesn't carbon wrapping them build up their thickness a heck of a lot? And also be very fiddly?

Any pics, Rich?

AeroCatch, which Neil has, also offer carbon-look versions - Not real carbon but I think quite acceptable : -

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2FRedRobin_05%2FCarbonfibre%2FAeroCatch_carbon.gif&hash=1cee4e6f22b95b8d9c2a66b182d7dbeea1a1287d)

In my case I'd be having fake carbon catches on a painted real carbon bonnet!  :grin:

Neil,

I've now ordered some carbon-look AeroCatches and am getting my head into where exactly to position them. So, some questions for you:

1) - Am I right in thinking that the position you chose was mostly dictated by you wanting to reduce their visual effect by colour coding them and hence not fitting them on the black carbon centre area?

2) - Did you consider any other positions, obviously taking any limitations of the slam panel into account?

3) - Do you think there are any parts of the OSIR carbon bonnet which should be avoided for fixing through?

Many Thanks,
Robin  :drinking:

RR, Yes I did want to keep the Aerocatches in the white painted sides of the bonnet which did limit their position a bit, obviously the pins need to have a panel to be bolted on and their are some existing holes in the slam panel that may be useable, but if you do drill new holes be carefull that you dont hit the bonnet release cable running to the left under the slam pannel.

You'll also need to place them on a fairly flat area, I put mine on at a slight angle as this made them sit better, the info says the narrow end should be at the front (couldnt work out why though).

I did have to cut some extra carbon from the second skin on the underside of the bonnet to alow access to the nuts when fixing but its very easy to cut and grind/sand and wasn't a problem.  :happy2:

So Robin you've painted your nice carbon bonnet and your going to display some fake carbon, have you thought of painting them red?  I am currently hidding an impressive 6 pack under a fake beer belly.  :signLOL:

Are you going to have a go, whats the worst that could happen?  :smiley:

Thanks, Neil  :drinking:

Thanks for telling me about the bonnet release cable! However, I'll be going to VWR to fit them and I'm sure they know about the cable.

Having now directed quite a bit of work with carbonfibre I'm quite at ease with it but I simply don't have either the tools or roof cover and anyway I like visiting the guys at VWR.

I think it's quite funny me displaying fake carbon on painted real carbon and I can always paint them red later if I want.

The reason that AeroCatch say the narrow end should be at the front is that if the catch were to lift for some reason, it's not facing an air stream which might then force the catch to fully open. I know that some of the racing boys (and girls) remove the stock oem cable and latch mechanism and so rely solely on the AeroCatches.

Something else I've recently learned is that some carbon bonnets have the oem latch glue fixed and this can fail through time and use. Our OSIR bonnets have them more securely bolted < Another reason why neither of us needed this mod!

But they do provide added safety and look cool (just like a six-pack under a belly) :laugh:

I'll post pics and add to this thread when done  :happy2:

My bonnet is now anchored rock solid. Being carbonfibre there was a certain amount of flex, though not a problem.

What Neil didn't say was the amount of carbonfibre dust all the cutting and dremmelling creates - It gets everywhere!

Re catches on the tailgate, I think it's probably because of regulations - An on-track nudge might easily release an oem tailgate lock. On a track dedicated car you wouldn't need the security of a lock. I've kept my bonnet lock fitted to prevent anyone opening my bonnet uninvited from outside as mine is primarily a road car. I have now decided not to fit a removable half-cage - Too tricky to take in and out.

Saw your car at VWR: Looking extremely purposeful - Very solid cage.  :notworthy:

I wish I had taken pics of Matt covered in carbon dust now.

....Cheers. Mike :happy2:

Although primarily functional (though I will admit to thinking they look quite cool), being black on red I felt their position and orientation needed some consideration. Mat @ VWR was very keen to fit the anchor posts in a metal part of the slam panel, so, like Neil's, we decided to fit on the 'wings' of the bonnet. I then decided to angle them so their centre axis joined the frontal meeting points (as pic):

My GTI in particular has a lot of '\  /' shapes in its styling and so the hard-wired designer part of my brain kicked in. It may have looked more subtle to colour code them red but I was too amused to forego the fake carbon catches on painted real carbon bonnet opportunity.

I noticed recently that one of the new cars (high performance Renault?) has plain black AeroCatches on an unpainted carbon bonnet ex factory.

There's something strangely satisfying about click-clacking them to open and close the bonnet. They should be opened before the oem central catch is released so there are no stresses. It means going back to the car cabin but so what. You certainly know that your bonnet has been securely anchored. They are also available with key locks but I thought this would get too tedious.

isnt the idea of having these to elimate the center catch??
Title: Re: Flush fit bonnet pins
Post by: RedRobin on July 28, 2010, 04:12:55 pm

....Their principle purpose is to more securely hold the bonnet closed and especially in a track racing environment where cars often 'nudge' each other and a flex or impact can open a bonnet or tailgate because the oem catch isn't up to it.

On a race car (or Hurdy's/JonnyC's) where you may want to reduce weight, the oem bonnet catch and whole release mechanisms would be removed in a strip out. The down side of oem catch removal is that anyone can open the bonnet from outside the car but race cars aren't usually accessible by the general public so no need.

Yes, the AeroCatches do look nicely 'racey' imo but I have had two instances of oem bonnet catch problems and one could have been very expensive indeed. So it provided justification/excuse for the mod.

....Yes. Both my problems were being unable to close it so it remained closed - The AeroCatches will override that problem.

One option I could have done was to use key lockable AeroCatches and remove the oem system but I felt it would be more tedious and I didn't like the look of the keyholes showing IIRC.

I like the stepped grill mod NeilM, how did you go about it?

Osir parts galore, looking the mutts nuts.

Congrats on the balls to cut the bonnet yourself.

Did you apply superglue the edges of the carbon fibre to prevent the carbon spliting?

I'm still very pleased with mine and am in the habit of opening them first before releasing the OEM bonnet catch from inside the car.

Where do you mount the pins to? Also do you think it would be an issue cutting a standard metal bonnet?

Good Point as to where the pins go, do the lights get in the way?

....No more of an 'issue' than cutting into a carbonfibre bonnet. The key is to mark it up accurately and cut with care and patience.

....No, when you next open your bonnet you'll see potential fixing locations which are not too close to the headlight units.

I'll see if I've got some pics later to help.

Cheers Robin,
I have seen them & thought, thats where to put them, but on the next thought, the lights would have got in the way there...Due to the pin length!

Okay, whereas the further forward that AeroCatches are fitted, the less leverage any wind/airflow will have to force open your bonnet, the anchor pin bolts obviously need to avoid the headlight units. At the same time, the other important consideration is what part of the car you bolt the anchor pins to. The bonnet slam panel is steel and sufficiently substantial. So I have fitted mine more or less in the same position as Neil. The difference is aesthetic in that I have dissected the angle between the bonnet edge and bonnet crease which meet in a 'V' at the front edge.

^ Dissecting the angle and marked out for cutting.

^ Angle dissected so aesthetic lines lead into the point of the 'V'.

^ There is no clash with the headlight units (OEM Xenons in my case).

An alternative would have been to use one of the twin OEM Torx positions to fix the AeroCatch pin through the slam panel to the steel car body itself (shown red in my case). But perhaps this is where it may have necessitated shortening the AeroCatch pin to avoid the headlight unit. This isn't possible on the passenger side with a Twintake installed because one of the Twintake's intakes uses the two OEM Torx fixings.

^ Best to have a little movement in the anchor so that the male AeroCatch mechanism can ease into the pin's female opening.
Rather like.... Let the Gentleman Sausage meet the Lady Garden gently.

I have chosen to retain my factory fitted bonnet catch in addition to the AeroCatches and am in the habit of always releasing the AeroCatches BEFORE releasing the OEM bonnet catch from inside the car. This avoids putting undo strain on the AeroCatch mechanisms.

They look sick. You know theres a serious engine under the bonnet when you need pins to hold it down!  :happy2:

They look wicked! (I'm a bit too old to use the word 'sick' unfortunately!)
