where is the cheapest place to get kyb agx's struts? And what springs do you guys recommend....ground control, eibach, h&r etc....? TIA Brad

Performance Suspension Technology (http://www.p-s-t.com) has them for only $389 shipped free. They don't list the 91-94 Sentra in thier catalog, but they do carry them. I got my AGX's there.

Your choice in springs depends on a couple of factors:
1. Are you lowering your car for looks or performance?
2. How much are you willing to spend?

Eibach ProKits are an inexpensive compromise for both factors.

Eibach Sportlines give a larger drop (great for appearence), but will leave you with hardly any suspension travel (bad for performance).
*Using Sportlines will your AGX warrantee because of the extreme reduction in ride height.

Ground Control coilovers are a bigger investment, but allow a high degree of customization (ie. spring rates and ride height).
*Something to ponder if deciding on Ground Controls is that they require some minor grinding of AGX struts in order to fit the GC sleave over. Word is that this will void your warrantee. They can also be noisy.

A recent group buy put together by members of this forum has created what many consider to be best springs available. The bad news is that the group buy is closed. The good news is that some of the participants are selling thier springs. See the group buy topic for more information.

And finally...Search the forum to find tons of valuable information regarding your questions.
