That's kind of in line with what I was thinking a while ago about bumpy and stiff suspension possibly not being good for these fragile gas tanks. My S14 is on Tein Flex, which is relatively soft, but there softer suspension options out there or I can even get something like Fortune Auto or Feal and have them spec'ed even softer. I also considered taking my solid subframe spacers out and I have aftermarket RUCAs too, but it's kind of extreme to replace those with oem arms and bushings since I don't think spherical bearings are that bad and the camber adjustability is convenient. Mainly the subframe bushings and coilovers/strut & spring assemblies, so solid subframe bushings are out of the question. I'll probably just replace the subframe and all other stock arm bushings with oem or Nismo or aftermarket oem rubber replacements if I can't find either when the time comes. You mentioned padding between the straps and plastic tank, which seems like a good idea too.
Interesting that in the last week or so, there have been tons of posts and talk about s14 fuel tanks in the various fb groups and two recent threads popping up on Zilvia. I guess it's around the time with these cars being over 25 yrs old now.
