I'm looking to replace the stock springs and shocks in my 280z, but want to retain stock ride height and maintain some comfort for long drives on bad roads in the northeast, and have slightly sharper handling. I want to be able to do 3-5 hours on highway and back roads without too much discomfort. And keep ride height around stock, a bit higher or lower is fine. I'm also starting to replacing all of the bushings, most with urethane (cheaper than rubber, although maybe rubber would be better for my use), and running stock tire size (185/70R14).
From reading around, it looks like the KYB GR-2 shocks would give me what I want, and that something like the Tokico HP or Illuminas is more aggressive, although I like the idea of having some adjustability (set it soft for long drives, but able to change for a firmer ride for more spirited driving). Any other shocks to consider?
I also can't find much information on spring options that don't lower the car, and are slightly more aggressive? Something like the Euro Spec springs? But those seem impossible to find now. Any recommendations here? I think the stock spring rate is ~100 lb/in front, and 130 lb/in rear.
Thanks
