Gonna have the floor off over winter- mainly as I think it's gonna be a lot simpler to swap to the M400 shifter that way, but also it's never been resealed.

Questions:

What happens to all the drilled out rivet ends? Do they rattle about? Is the solution to inject a heavy waxoil to kinda stick them in place?

Stainless or Alloy rivets?

Any wise words or learned wisdom, or is it just drill, drill, drill some more, then rivet until your arms fall off (air rivet gun sounds like a plan).

Thanks
Andy

I used (based on recommendation) hex head screws. I also used neoprene strips to seal floor

I started using hex head but thought they looked horrible(sorry Bondy)so went back to alloy rivets by hand and yes it's a killer. Used neoprene tape and did waxoyl inject chassis and have never heard a noise.

Andy,

My M400 is in with Noble Motorsports just now for a service, MOT and a few other bits and bobs. One of the things that has long needed doing to mine is floor off, clean up, back on and reseal.

Noble Motorsport however have actually recommended that rather than go to all that trouble and cost and still end up with what is apparently a somewhat less than perfect design, is that I should go for a completely new floor, this being a concept that has gradually evolved over the years like many other areas of PH'er Noble design, in order to give better dynamics and to solve the 'always there' problem of water ingress.

I can't advise one way or the other if any of the perceived benefits will actually ultimately be enjoyed, but it is maybe something that other Noble owners on here will be able to give the benefit of their own experiences of, prior to you committing to your own scope of work.

Anyway, leave me to live with my car between the time I get it back (hopefully mid this month) and next spring, and I'll then be able to let everyone know whether the floor replacement (as opposed to modification) was worth the money or no!

ATB,
Shaun+

I'd be interested to see what Noble Motorsport do differently- it's just a flat sheet isn't it?!

Labourious but looks simple to do- and gives me access to the tunnel.

thanks all

Keep us posted Shaun, would like to know how they could do this without altering the frame.

When I did mine I bought 2 sheets of slightly thicker grade Ali from a company called aalco near me and used the old ones as templates, repainted frame, neoprene taped hex screws jobs a gooden. Labour cost 0 materials about £100. No rattles heard over my exhaust!!!

yep
i did exactly the same, simple to do and just a bit labour intensified, i neoprene taped it, also used sikoflex (i think its called), a bead of silicon round inside and screwed it back up
Also shot loads of wavoil into the frame, never had a leak since (famous last words LOL

Had mine drilled out up on a 4 poster, cleaned up panels, bit of hammerite smooth on any chipped chassis areas, waxoyl in some holes and then 3 tubes of black silicon before whacking the whole lot back together with black self tappers. Took 2 afternoons and an evening from start to finish but the floor was in great condition as was the chassis.

Symptoms would be wet feet :-)

On mine the driver floor edge was coming away slightly, so it was wet around driver seat by the door and at the rear by the bulk head.

Other signs of wetness could ingress at the front bulkhead

water ingress behind seats- well anywhere really.

I'm only thinking of pulling mine off as it'll give me better access to fit the improved shifter.

I think that once it's done then it shouldn't ever need doing again.

Mine was wet in the footwell area and behind seats, the floor wasn't too bad just a couple of iffy rivets, but once the floor is off you can really see where its rotting from the side fixed to the frame. Also check drain holes are not blocked which prevents water draining away, drill them out a bit larger and possibly drill a few extra holes.
