If you have some extra $300 go to <a href="http://www.Enjukuracing.com" target='_blank'>http://www.Enjukuracing.com</a> and buy the Apexi WS Coilovers. For the price its worth it to get these over a spring/shock combo. Although I still dont know how stiff they are. Apexi is good at not telling anyone anything.
Otherwise GAB makes some good shox for our car that will work very well with aftermarket springs. They are adjustable as well. <a href="http://www.Shox.com" target='_blank'>http://www.Shox.com</a> has them. If I had to get shox these would be my choice.
Tien also makes very good shox for the 240SX. Although a little more pricey they are very good quality. For the $ GAB is my choice. <a href="http://www.teinusa.com" target='_blank'>http://www.teinusa.com</a> for info, I have no idea who sells them <img src="#/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=':('>
Also, see what whiteline has to offer. They make excellent stuff for the 240sx. Although I wouldnt buy their springs. You can get there stuff @ [url]http://www.mofugas.com[/url
If I were to get springs for my s14 I would probly get the Eibach Prokit (or something simular). As this is nowhere near how stiff I like my ride but there are not many options available for springs and 240SX and that is why I would spend the extra $ for the Apexi Coilovers. Just make sure and find out what spring rate they are. I would like to know because my old 5Zigen springs were about 290/lbs, that's about 30% stiffer than the ProKit's. And to me they weren't too stiff. Now that I have my HKS Hyper Dampner II Coilovers I know what stiff means (700/lbs soring)... and I love it! <img src="#/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> (I'm the only one though)
