Recent posts on interiors has got me thinking about my build. Having trawled the forum for ideas, I came accross this picture (hope the OP doesn't mind me borrowing it):



I really like the exposed chassis tubing, higlighted in silver against the dark panelling (can't make out what this is). My first thought was that this would prevent double skinning of the floor. My next thought was that the panelling has been attached to the 'wrong' side of the chassis.

I'd be interested to hear on what issues people think this would create, as well as the panelling material (it doesn't look like carbon fibre to me, but it's not entirely clear from the photo). I was planning on using sound deadening material around the cockpit area as much as possible, and wondered whether this would make a difference to the viability of the panelling as shown in the photo.

Thanks all!

not very easy to keep clean, and apart from some extra space I see no reason why this should be any better.

I agree the exposed tube do look nice.
The skin on the outside should not make a difference to the car as long as it is strong. It needs to be ali as a minimum in order to provide stiffness to the chassis.

Looks like c/f on the floor. Not sure about the side panels.

It will be difficult to keep clean as it's no fun lying on your back under the dash!!!

Reminds me of my Ariel Atom smile. I personally like it, so go for it

Nice clean look, I may borrow some of these cues on my up-coming Can Am build. It looks like the tubing may be silver powder coated and the panels black leather (or equiv)? Are those stock Ultima pedals with aftermarket covers?

Don't think they are standard Ultima pedals.

If you want to have yours powder coated in silver then either get the Factory to coat the whole chassis that colour or get it bare metal and have it done yourself. You can't powder coat over powder coat.

Looks to be Sparco (0378713) pedals. Cost's around 30 GBP

As Tango says, the first thing I thought of when I saw that pic was my old Atom! The does look nice, but I wonder how much work was required to re-route things that would have been attached to those tubes, which are now exposed. Keeping that floor pristine will also be hard, maybe the owner takes his shoes off before he gets in ;-) I wonder if it's load bearing too?

I would have thought that having a single skinned floor will introduce more noise into the cabin as stones clatter under it... I don't know if heat mgt might be tricky or not? Depends if any insulation can be put on the otherside, I guess.

Certainly looks good, would be interested to know how practical it is tho'.

The car with the exposed chassis was by Technocars: http://www.technocars.de/index.htm . They were, or maybe still are, a bit overpriced, but look to be nicely put together.

I like the look of it, and paneling the outside of the chassis will (very) slightly add to the stiffness (erm, I think?). It may also free up some room for your accelerator pedal foot (or clutch foot on LHD cars).

I can't believe people worrying about it being difficult to clean. rofl

??? If someone is going to spend that money and put that much effort into making the interior look like that, surely they'll be wanting to keep it clean... I would. That floor will be a nightmare to keep looking good tho', it'll scratch & tarnish very quickly, which is a shame frown

Looking at the other pictures on the website (many thanks for the link dandare), it looks as if they have done the whole chassis (and wishbones) in silver.

I wonder if you cold just paint on top of the black powder coat (with a bit of abrasion) on the chassis tubes in the interior? I know this would be less durable, but I think I'd prefer to keep the rest of the chassis black, since it's easier to get a colour match if you ever need to touch up , as opposed to trying to match a silver powder coat colour with a silver spray paint.

On second thoughts, even if this was possible, deciding where to stop and start the silver paint is beginning to sound like unwanted aggro...

Thats the kind of thing I was worried about. I assumed they could simply attach to the same tubes, just on the other side which is now hidden behind the panelling. With the important caveat on the quality of my posts that I haven't started the build yet, so don't really know what I am talking about, it looks as if there is plenty of clearance between the chassis sides and the body side pods, which might have otherwise caused an issue.

Me too. I suppose you could still double skin the floor, although you would lose some of the 'purity' of the look.

Good point. Having nosed around on your Facebook page and the photos of your heat and sound insulation (nice one - thanks!), I reckon it can just go on the other side of the pannelling.

There - nearly talked myself into it. I might ask the factory on whether they think there would be issues, and see if there is any scope on the powder coat colour.

Honestly I am not picky at all but from time to time you have to clean a car and then I like it easy......

Thanks for part number GTR-TT. The best part about building these cars is personalization, no two are alike.

Apologies for resurrecting this thread again, but I've started the build and am about to make the final decision on whether to go for the exposed chassis tubes.

The one problem I can see is that, beacause the alloy side panels are mounted on the other side of the chassis tubes, the coolant pipe will be pressing up against the side panel.

On the conventional build, there is a gap between the panel and the coolant pipe (i.e the panel is mounted on one side of the chassis tube, and the coolant pipe is on the other). Do you think heat insulation material would be enough to stop the heat spreading too much?

Cheers all.

It looks nice but not practical IMHO. Lots of dirty not easy to clean, huge road noise and hot from water (coolant) lines.
I strongly suggest to go for the double panel.
Cheers,

If you want to do something different then have a go. However, only do it if you are sure you have thought of all the knock-on effects and you have a solution to them before you start.

If you change something it will usually affect a number of other parts of the build further down the line.

I know this is not s specific answer to your question, but take it from someone who has had the pain changes made that seemed a good idea at the time.


If you can get them to work though they do make the whole build so much more enjoyable.

In reference to the flooring, it looks like moon mat http://www.lonseal.com/show_product/LONCOIN%20I
We install moon mat as a Utility Floor Option on our helicopters. We velcro the bottom and sew on some edge trim and it's good to go. When dirt, just rip her out, soap and water wash and re-velcro back in. tada

Interesting idea and it sure looks like the stuff you mention. Easy to clean and when it gets very tatty, easy the renew. I may consider it in my build
