Ok need new 240z shock Inserts for my struts. Just used Gabriel gas shocks and they lasted ok. But would like something but better, not adjustable, just so I could go little lower maybe. Any one with a shock book out there to help out?

I haven't got heaps of $$$ so budget end would be good. Using 250lb springs now too. The cheap gas were well suited to 195lb springs, possibly little more- unlikely to 250lb.
