Neoprene between chassis and body

Plus 2 Discussions

I’ve been considering using neoprene between the body and the chassis instead of the traditional material, and wondered if anyone had experience of this. Previous posts suggest this can be bought from Spyder. Any ideas on what thickness I should use, or should I just phone Spyder and get theirs?

Thanks.

Sean.

I used closed cell neoprene rubber in 1/2 inch thickness between the body and chassis. Worked fine. I didn’t want anything to hold water. Forgot where I got it, but it’s used on wet suits - so someone who makes them would have it. I believe it’s also available in sheet form from suppliers of industrial padding.
Good luck

I used 1/2 inch thick closed cell neoprene rubber sheet for my Elan when I rebuilt it 26 years ago. Over 26 years the exposed bottom edge of the sheet has gone a little hard but otherwise no problems or signs of deterioration.

I know I’m attempting to revive a really old thread, but the reason for my interest is “longitudinal research” and Rohan, you’ve had neoprene saddle material in use for a VERY long time now, if your Elan is still on the road: 30+ years!!!

Wondering if you’d care to update the forum on the performance of neoprene as a chassis saddle material? Specifically: has the material compressed more than you’d expect from the original felt and is the body/chassis fit still snug and as noise/squeak free as you’d expect, etc.??

Much thanks for your real-world observations :mrgreen:

Hi Randy
31 years now and same comments as at 26 years. The closed cell neoprene foam is a little hard at the lower edge where it is exposed between the chassis and body but in the more protected areas that i can get to - eg around the access hole in the side of the centre tunnel it appears to still be in perfect condtion.

The foam is still a tight compressed fit that seals the gap well and does not let water in. No squeaks or other noises that i notice

cheers

Awesome. Thanks for that update, Rohan.

I think your car and experience are a good insight into the material and it’s suitability.

Long live neoprene!! :wink:
