Fixing side panels - questions and photo request
Sloan85 - 25/4/13 at 06:51 AM

I am looking at fitting my side panels fairly soon and was interested in using rivnuts so they are removable.

What centres should I be fixing the rivnuts at? I was thinking about padding chassis rails with thin adhesive foam to stop the panels rattling, is there anything else I should be doing?

Does anyone have photos of their side panels being fixed to the chassis?

Sorry cant help with spacings as I riveted and bonded mine. But I would ask yourself, do you really need removable side panels? I'm sure that you would need quite a few rivnuts per side to get the panel tight and that many rivnuts could weaken the chassis due to the amount and size of holes you would be drilling in the chassis rail?

Just a thought!!

As above, my side panels are bonded and rivited too, you dont need access to anything once there fitted, the inside panels on the tunnel you can have removable if you need to get at the prop, fuel lines etc.

many pictures in my archive, beware of carbon

I was thinking removable in case there were ever a problem with the pedals. Just got all the pedals sorted at the weekend and I can't see how I could have done that if the side panel was in place.

Fasten them on with Velcro Can't you get at your pedals if you remove the scuttle ?

If you make your battery tray removable, you get easy access to the foot pedals and can bond your side panels to the chassis. On our first Indy, we split the GRP battery tray along the drivers footwell chassis rail to make it easy for access to the pedals.

There was some pictures on our website but we lost the hosting a few years ago....

or cut a hole out so you can gain access from the top.

Hiya,

I used rivnuts to secure the side panels on my build. A couple of pics:





I used M6 countersunk screws and some of these from CBS to spread the load a bit along the top in the engine bay and so that the bonnet sits flush. Along the cockpit sides, I countersunk the holes in the aluminium hockey trim and used the same countersunk screws. To secure the underside I just used M6 cap heads and normal washers.

You'll also find that the side panels are quite a bit bigger than the chassis, mine were up to 10mm wider in places, you will need to seal them with something to stop water coming in.

I also used rivets and sikaflex, plus plastic spacers to make up the gaps!


Sloan85 - 2/5/13 at 07:12 AM

If I were to use rivnuts what should they and the countersunk bolts be made from? Aluminium, steel or stainless rivnuts?? BZP or stainless bolts?

I can't remember if there are combinations of metal that shouldn't be next to each other if they are likely to get wet.


Cheers

I bonded the side panels on, but split the top panels into three section, so I can get to the pedals easily, in fact I fitted the pedals way after the side panels.

As mentioned, I would be concerned about weakening the chassis with size of holes required for rivnuts.
I will be wrapping my side panels over the top chassis rails in the cockpit to ensure a nice smooth finish without the need to edge trims. Il be using counter sunk rivets on the side panels so I can vinyl wrap over the rivets.
I have also used PU sealent to ensure a water proof seal (and add some strengh) as it protects the chassis from water ingress and my trousers!

Hi James,

I used stainless M6 rivnuts (9mm hole) with a small shoulder from memfasts on eBay, £2/3 for 25 I think. I worked to roughly 25cm spacing between each i think. I then used button head stainless M6x25 bolts to secure in place. As I've put some 6mm foam from CBS on the underside of the bonnet there's no issue with having the proud bolt heads. I also used larger M6 repair washers under the bonnet area. Must have taken me a whole weekend to do it so riveting is certainly faster, but I'm happy with the finish I've got. Expect I'll probably have to put some sealant/bonding agent on once the car is finished though.

All done fairly cheap with bits off eBay!

Cheers,

Ben

It's been mentioned about weakening the structure, well we all have about 100+ holes
underneath our car for the ally under tray.

Personally I used M6 rivnuts with galvanised Allen key dome bolts and washers, but don't go over the top. Space them efficiently.

As mentioned be prepared to shim the panels as on MK the panel is slightly bigger.

4.5mm holes for rivets, are are meer flesh wound compared to the gapping 9mm holes required for m6 rivnuts. I was reluctant enough to put a few on my top rails for my brake lines, but along the whole length of both top and bottom rails would be iffy IMO. also using normal rivets at decent centres makes the panels part of the structure, doing it with lesser rivnuts will not give as much.
