250 GTE floor

Post by Howser »

I had some requests for images of the floor cross section. These images are of the area directly under the driver and passenger seats. I tried to get a much detail as I could but the saw distorted some of the sheet metal as it passed through. The top layer of insulation looks to be some kind of loose fiberglass with an aluminum layer in the middle. The bottom layer of insulation is some sort of semi rigid foam. If anybody would like specific images, let me know.

Wow, that's interesting! No wonder they all rust.. We have a big sponge in the middle of the floor! Is there a similar system by the rear seats or is it flat metal? I have heard about this system, but this is the first time I have seen photos. Thanks.

I guess as with all things Ferrari, variation is the rule rather than the exception.

When I redid my floors on 4969 there was only a top layer and bottom layer of metal sandwiching the fiberglass. There was also a sort of cross brace that was under the seats and had holes of for (I guess) seat belt anchors. The bottom metal was like an upside down cover for a metal container that was tack welded on four sides under the driver and three sides under the passenger - no sealing around the edges and even if there was, the holes for the seat belts were unplugged. Needless to say the fiberglass acted like a sponge and the bottom sections were badly rusted. Fortunately the uppers were in very good shape. But there was no middle layer of metal and no foam rubber and finally no evidence that the panels had been replaced before.

Only a single layer underneath the back seat is the same in my car. The floor underneath your feet is double layered with no space between the panels but when you get to where the floor meets the firewall, the firewall is double layered with insulation between the panels all the way up to the bottom of the cowl.

Howser's car is not showing the floor structure but the inner box section located next to sill. Many sheets making up the sill structure come together here so it is pretty complicated to figure out how these cars were actually built.

I also think that the sponge is not part of the original structure. Hard to say how the car was repaired, but looks like the bottom sheet was screwed in place.

It kills me that cars this healthy are scrapped for replicas. First it was TRs, SWBs and GTOs. Now it is all about California Spiders, none of which will ever drive or look like a real thing. What's next?

Best wishes, Kare

I am with the same opinion.
there is normally only one(1) room under the chairs and filled with horsehair ( rosshaar)
this material can be found in very good isolated mainly prewar covertible hoods
nowadays diffucult to find such a compeny who used this.
the foam will melt away fast just above the hot exhaust.

"Whats next?" the price of GTE will arise upwards

The foam material looks to me like isocyanurate insulation foam, which certainly was not invented when that floor was made, and the fact that the self tapping screws are shiny makes that whole layer appear added very recently.
