Been doing some research on coilovers but this is about all I found so far...anyone else have info?

I have Ground Controls on my NX. Here is a link (http://www.sentra.net/solm/september01/suspension.shtml) to an issue of Sentra Online Magazine that has an article on Ground Controls. It's a slightly different process for B13s, as the article is for a B14 but the basics are the same.

Pretty much you're going to get what you pay for here. A set of $149 coilovers is going to perform like a set of $149 coilovers. GC go for about $400, but they also have a reputation for quality. Nearly everyone I know in SCCA racing is running GC.

Unless you go all out with a set of custom threaded body coilovers, GC is about the best you're going to get.

Of course you realize the stock shocks are not going to be able to handle the higher rates, so you'll need better shocks along with them.

I heard that GC is one of the best out there. I'm getting buying it in a month. I was also told that there's a company out there that's about to come out with a better setup than GC. (Remeber I just heard that.) I don't know anything about the company nor their current projects.

I know the Progress Group has done some development for the B15 chassis, but I'm not sure if it has reached production. They have a good reputation in the Honda community from what I've seen.

There's also Truechoice, Motivational and Shocktek, but I don't know if any of those are still in business. Those three all make full-coilovers, not just the sleeves and springs like GC. They're also about 3 times the price. (of GCs and the struts to control them properly)

Back to the rumors, I've read about a rally company in Australia(?) called HotBits that apparently can put together a coil-over setup, but I know nothing about it.

That's about all I can think of off the top of my head. Like MaddMatt said, GCs have a reputation for quality and there's a lot of people who have gone that route and can provide feedback/help.
