Body Mounts

[h2dca]

Quick question, winter work going well and fortunately chassis is in good condition so a good scrape/wire brush and hammerite prime/top coat/waxoyl to complete the job.

However I have decide to lift the body an inch or so, remove the rubber spacers and clean and rust proof the mounts. So my question is can I replace the rubber gaskets between the body/chassis with nylon block cut to size, it seems a better material, hard wearing, does not compress and degrade like the current rubber.

Any thoughts

Thanks

The rubber is probably intended to deaden vibrations/noise. Nylon would transmit that noise.
Polyurethane might work better if you can get it in sheet form (just thinking of poly suspension bushes)

It has probably taken the thick end of two decades for the rubber to compress so if you were to replace with the same again it should do for a while

Thanks leorest, interesting point, just changed the bushes for nylon and uprated the springs to competition ones so the car is pretty solid already.
Maybe rubber is the way to go as I think my fillings will become dislodged

I did wonder about this myself a couple of years ago when I did a similar job. I was worried that if it xmitted enough vibration it may cause the body to crack, so went for standard rubber ones.

How thick was the rubber and has it lasted well?

The old rubber didn't seem too bad for 20 odd years,but it's hard to tell how much it had compressed. I think the body will sink over time and I believe it's this that causes some of the problems like the doors to go out of line, especially on a drop head. I guess it's like most things in life.....a compromise. Using harder materials like nylon will stop it dropping but will transmit more vibration and noise and maybe cause stress cracks. The softer rubber will probably let it drop slightly over time. Personally I'd go for the rubber......did I just say that.
