...or Subframe solids? This guy has diff+subframe solids. I not going that route, I am going to run Nismo Rubber ones in the diff, and will see later if keeping the current ES for the subframe (re-lubed cos they are singing right now) or changing to nismo solids in the subframe or keep them as a cool decorative nismo part. Nismo ones came with a small red rubber to minimize noises. However I am not sure how much effective will be.
