ehehehhem..<--clearing throat, welp the suspension systems on the bad ass scale are like this. For all SE-Rs the fornt suspensions are the same. B-13s up to '94 have independent rear end which allows more passive steering and adjustablity of camber and toe which are not adjustable with the B-14s 95-->and on.
Shocktech and Truechoice coilovers which cost roughly $1,500-$2,000 for all four corners allow tailored spring rates and double adjustable rebound and compression settings.
Down the food chain a little is the Motivational Engineering System featuring Koni adjustable shortened strut bodies and single rebound adjustments for around $800-$1000 for the whole set half the price and almost as good handling (look for this set-up on the new SCC 1.6 Sentra)
Then there is Ground Control Coil Over Sleeves and you could go with their racing double adjustable shocks. The sleeves you can fit over KYBs, GABs etc., and run around $400 without shocks. Double adjustable shocks put this system around $2000 also so you pay a premiunm to use their shortened body racing struts.
In addition to the aforementioned coilovers i have to stress the fact that the Nissan suspension system is very ride height challenged and if you are doing anything resembling track use or get after it autocrossing, i would stay away from Eibach PRo Kits and other normal wound springs. If you lower the car any, you crash into the bump stops on just about every little bump, and under any steady cornering. Pat G and i demolished his Tokico blues on Eibach Pro Kits in about 12 autocrosses.
Also in addition to the suspension systems you want to get some camber plates from Stillen or Grouind COntrol (which also allows caster adjustment in addition to camber) Also you can opt for the Nu-Tech front subframe brace and sway bars that are fully adjustable for the B-13 and front adjustbale for the B-14. Or Suspension Techniques makes front and rear sway bars for about the same price as the Nu-Tech but they are not adjustable.
Really the whole issue with our cars is to keep the damn front end from bottoming out. I am running 325f/450r on Ground COntrol Sleeves over AGX adjustables, stillen camber plates and and Suspension Techniques rear sway bar and strut tower braces. I can still bottom out the front suspension. Don't get me wrong though, its only lowered one inch from stock, and i destroyed STS in a local autocross so the suspension is working but it can WORK ALOT BETTER WITH MORE TRAVEL...
So if you do choose to spend a little money on the suspension make sure you get a shortened strut body like the ones i mentioned above...This is the ticket to get the SE-Rs to handle.!!
