Boot Lid Spring tension.

Hi,

Does anyone have a solution to the boot lid springs not holding the lid open. Our 1997 Mk 1 MX5 annoyingly keeps closing on us or hitting us on the head when opened fully. It has a spoiler and our local Mazda dealer was most unhelpful and just said “They weren’t meant to have a spoiler!”

My Roadster has a spoiler, and even on the strongest setting it still self closed. I fitted a ram.

Here’s a pic I took when I was trialing the ram [that’s why  the bracket is unpainted

Your Mazda dealer is not very knowledgeable, some Special Editions came from the factory with a spoiler.

 

The bootlid on my Mk2.5 has no spoiler but still falls down on occasion

The Mazda made boot rack that I have (mk 2.5) came with stronger torsion rods (which could be fitted) to offset the extra weight. Not sure how easy these rods would be to find though.

I think the part numbers for the uprated boot springs are N115-52-791A and N115-52-792. Order at your own risk, I’m not 100% sure that they are the uprated ones. They are listed as “With Turbo”, so assuming the Turbo had a spoiler from build, which is also listed as “With Turbo” then I suspect they are the uprated springs.

Or just cut a length of bamboo cane the right length to go between the hinge bolt and the inside of the back panel floor, stays up in the strongest of gales and weighs/costs nowtWink

 Moss do a real good aftermarket kit for the boot, works really well, made well and have stood the test of time so far, i recommend them, i have them on my Mk 1 and Mk 2’s.

Thanks all for your “interesting” comments.

Fundamentally, the dealer is correct, but he would better have said “The bootlid springs on your car are designed for a boot without a spoiler and so any extra weight will affect their performance…here is the part you need, please empty your wallet into here…keep going…keep going…and your shirt…”

The OE Mk 2 boot lid spolier kit comes with new tension springs to take the extra weight of the spolier when fitted, you just swop the springs , so you can get extra tension OE Mazda springs, i can not see why the Mk 2 ones will not fit the MK 1, i’ll check tomorrow,and post up.

Thankyou Taff, you have cheered me up on a gloomy day with your reply.  That is my sense of humour, straight to the point.  Congratulations!

Cheers Geoff but it isnt humour for humourssake - after faffing around trying to make my boot springs man enough to hold-up my bespoilered boot lid, one day I did theboot cane mod` as a temporary fix to a very annoying problem, it then became a permanent fixture which out-lasted our two year ownership of the car and has since been transplanted into our latest Eunos.

It is even better than fitting Mk2 springs as it even allows the boot to stay up when a heavy suitcase full of MX5 spares is attached to a boot rack:
