Guys,

Very basic write up here of how i have made my own mod to ***ist the boot lid with opening the full way with the use of an expansion spring. Guide and pictures below, as always any work copied is at other peoples risk!

Bits required:

1x 180mm long expansion spring
1x 6mm x 80mm long bolt
3x securing nuts
1x washer
1x cable tie (heavy duty)

I still want to tidy this install up but thought i would share with you all the work so far.

Step 1 - choose a side to mod, i went with the right hand side lifting arm.

Step 2 - gentle to remove the carpet trim, i suggest a blunt knife or similar to ***ist. Remeber to remove the plastic securing clip by the lifting arm and the one behind the carpet level with the rear light.

Now i would strongly recommend removing the whole carpet ***embly but I wanted to see if this could work so I worked with the carpet in the way.

Step 3- Remove the 2x plastic clips holding the plastic trunking to the lifting arm, and replace with a 6mm x 80mm long bolt.

Step 4 - Once the bolt is through, add a securing nut to the bolt lightly clamping the plastic trunking to the steel inner bar. At this point you can now add the spring and add the washer and retaing nut, the washer is here only to prevent the spring sliding off the bolt.

Step 5 - Locate the pre-drilled hole on the body brace bar as the picture below and add the cable tie and pull close to the brace bar.

Step 6 - the danger part - please please be careful incase the spring snaps back as it could cause injury to hands, eyes or face. - Right stretch the spring and hook onto the cable tie, once secured the job is near completion.

I would recomend testing the boot operation at this point, again be careful and operate the boot slowly to ensure no damage is caused and the boot shuts with a bit of resistance behind it. Once closed, place your hand infront of the back window before opening with the remote. I suggest this in case the spring you have chosen to use opens the boot too fast and causes damage, hopefully your hand will provent this!

To be honest you will have the feeling if the spring is under too much tension when trying to shut the boot, if it feels tight get a better spring as its not worth the risk causing damage or injury.

If happy with the operation then re-fit all you carpet and admire your new fully opening boot! No more putting stuff on the floor in the rain!

As mentioned at the start i will look to tidy this up but i will see how the mod goes for a while before i do and report back. I will also ask the father in law if he can get anymore of those springs as those who want to do this may want one.

Cheers Dan! Now to find more to do!
 
No worries.... For future reference, to get the vid direct into the forum you need to paste everything BEFORE the & symbol in the URL.

Perhaps that can be added to a "how to" thread at some point ?
 
EX mod Jay as Adam said where did you get the spring from.Also could this mod be done with a Damper instead of a spring.
Rep on its way :)
 
Excellent Writeup mate.
This mod really sets the car aside. I just wish Honda would do this mod as standard on the Accord.
Top Writeup and the end result looks great
 
very good mod. + rep for you.


The little mods that seem so simple are always the best.
 
Guys,

many thanks for the kind words! I didnt think anyone would actually be interested in this mod.

I got the spring from the father in-law who got it from a machine at his work (its ok it was a spare), he did say that they have to order these in so i will see how much they cost.

But i would see any online manufacture or ebay doing something similar. The spring should be able to stretch to twice its size and easily recoil to its original state.

Thanks for the rep points!
 
Jay i was having a look today and i can see the reason for the long 6mm bolt.
Im thinking was this to keep the spring away from the fitted boot lining.

Indeed Brett, also avoids the spring catching on the plastic housing. I'm going to keep my eye on this for a few weeks before i fix it in perm.
 
Cheers bud im looking into it ;)
 
Me too Asher, shame the video link is no longer available...has anyone else other than James done this ? or found another way ?

yer iv been looking on ebay for ages trying to find an expansion spring since i seen this thread haha but cant seem to have any luck :(

Jay,

just a suggestion as i cant see the video as it doesnt work any more, but when u pop your boot, does it fly up and bounce? if so maybe installing kitchen unit dampers might work? you no the type that when you shut a kitchen cabinet door it allows the door to shut slowly....
