installing bonnet pins

[sl8r]

Hi all

I am about to attempt to install some bonnet pins on my v3 and was wondering where the best place to put them is?

Also are there any pitfalls that i should be aware of?

help / pics appreciated

Is the latch on the front not good enough? Or do you have an aftermarket CF / FRP bonnet that doesn't have a latch?

Scoobydoo, if you have a track car you can't have a latch as it is removed. So marshalls have easy access to engine bay in case of an accident, mine had to be removed for scrutineering.

Koom on here drilled mine as even my mechanic didn't want to drill through my carbon fibre bonnet, he would have some good knowledge on hte how to's. Would recommend pming him, definitely the old addage of check twice drill once would be a goer haha

My mechanic recommended putting them here as in the pics, same place as his rally cars so guess it's a good place.

Can take some close up photos of mine if you want?

Pic of my location of bonnet pins.

Ah okay, fair enough then. Would they be the positions of the rubber stops for the bonnet?

its pretty straight forward (drill 2 holes) ......i did mine same as wrxer but left the latch in...works swt

Mine are, others I've seen put two around the front middle of the car. Problem with no latch, technically anyone can open my bonnet now haha talk about security issues. Seen a few guys with trackcars having a padlock through their bonnet pin.

i had these but with a lock in them http://www.fortyone.co.nz/parts/show/2038/J's%20Racing/Aero%20Catch%20Bonnet%20Pin.html

they were pretty good, did jam up on closing now and then, they just needed a bit of greese.

Did you have to enlarge the bump stop holes?

Yeah those are the ones you want if you don't want security worries

I have them cos I cut my bonnet up and dont trust the structure - oh and re-welding caused it to flair up on the sides...

Has anyone had any issues with the screws rusting up, have seen people use rivets instead? thoughts? first hand knowledge?

I used screws in mine, never had an issue with them (they are coated or stainless from memory?).

Bonus is that when you need to remove the pins (cos you smash your bonnet in a race :'( ) you just unscrew them rather than having to drill them out like rivets.

Most pins come with those funny backing things that the screws thread into but you dont need them, just drill the holes for the screws quite small, since the alloy bonnets are soft the screws bite in really well and they dont come loose or anything.

who are you asking? the bump stops that come with your bonnet pins should be the right size for your pins.

The black stop your bonnet rests on, do you need to a. remove them and b. enlarge the hole if you were to use that spot.

The sets ive had dealings with only seem to come with cheap Zinc plated washers/screws. Ive always change them to stainless. Ive made one set up using all stainless. Only thing i had to buy was the clips.
