Rear upper spoiler fitting how to.

Ok, before I start please read this polite statement. This is how I fitted my spoiler, it isn’t the only way, there may be better ways but I didn’t find much info when I was researching.
The only info that cropped up was from fellow member on here particularly Darthblaker7474, thank you for your info.

But proceed at your in risk. If you drill in the wrong place it’s your fault, not mine check check and check again.

Here we go.

I manage to pick up a 2nd hand factory fit spoiler online and I was over the moon. It was the wrong colour for me (silky silver) so i resprayed and lacquered at home using rattle cans but I couldn’t find out how it should be fitted. I hunted high and low for the official fitting instructions online but found nothing.

Having contacted the seller (who had removed it himself) he told me it had 2 little plastic sockets in the tailgate that the long grub screws on the underside of the spoiler located into.


The socket is on a double skin section of the rear door so I either done as suggested by darthblaker and drill the outer skin and drill a bigger hole in the inner skin and plug it when complete.

I thought I’d try out an idea I had using the expanding trim tags


And not use the plastic expander screw. The factory grub screws are pictured in the forefront of the picture.

Initially I decided on using a paper template that I stuck it onto the car and drew around the foot of the spoiler to get a location, I marked the position of the paper on the car with tape and pencil lines to aid relocation, then took it off and pressed with my finger onto the underside of the spoiler to make an indent on the paper of the threaded insert of the spoiler.

I wasn’t convinced I had it spot on so I decided a cuppa would help so after much head scratching I thought about a blob of blu tac. I wiped a bit of polish onto the contact area of the spoiler before I place the blob of blu tac onto each fixing point


I lined the spoiler up with the template on the car and pressed on then gentle removed the spoiler. Because I had put a spot of polish on the fixings the blu tac stuck to the paper and stayed with the car.


A quick jab with a skewer made a centre point,


And proved that the paper template idea had worked too


Now this is the point of no return. Now the drilling starts. If you are using this as a guide please check and triple check you are happy with the position before you start drilling.

With a centre punch mark the tailgate to give the drill a starting point. For my own sanity I started out with a 2mm pilot hole and stepped up 2mm each time till I had drilled an 8mm hole in my rear door.


I test fitted the trim nut thingy


And trial fitted the spoiler


It sat there all by itself. When I took it off again one of the trim nuts came out and proved the original threaded grub screws were too short and the trim but legs weren’t spreading


I painted the bare metal of the drilled holes and left it to dry.

I had a length of threaded bar in the garage but you could cut the head off a bolt to make longer locators


The original pins were about 20mm and the new ones I made were 30mm

In case there was any overspill of tiger seal when I fixed the spoiler I masked off the area around the foot to make clearing up easier



A bead of tiger seal was placed around the drilled hole and the trim nuts were pushed into the drilled hole.

My new 30mm locating rods were wound into the spoiler.

Tiger seal was used on the foot of the spoiler and the spoiler was pushed home onto the tailgate.

While the tiger seal was still soft I removed the masking tape to remove the small amount that had escaped.

The spoiler was on the car and supporting itself while the tiger seal cures. I added some masking tape to be sure (but to be fair I don’t think it’s doing anything.


If I was to improve on anything I’d put a bit more tiger seal under the foot as not much squeezed out when I pressed the spoiler on. I’ll probably mask it up again when it’s cured and run a small bead of sealant around the foot just so I’m totally happy.

All in all I’m satisfied with the result and I hope this is of some use to someone in the future.

Tony.

Cracking write up

Would you consider transferring this guide with pictures into a new wiki article?

EDIT: I have just created a corresponding wiki article .

Someone just needs to "populate" it with appropriate text and pictures.

Yeah sure if you think it’s of use on a wiki then no problem. I’ll have a look.

Great job looks good

Look brilliant, glad you took your time unlike I did

Absolutely fantastic! I’ve got one of these spoilers to fit that I got years ago for my last jimny when I worked at Suzuki but never got round to fitting it. Will definitely be re reading this when I get round to fitting it! Brilliant write up

Excellent. That's how to do it both fitting and write up.

I have transferred this entire guide into this wiki article.

If anyone comes up with some improvements to this installation method (or with alternative methods), please add them to that wiki article.
