I was wondering what the benefit of coilovers really are?
I mean what is the performance benefit and also what is the difference between the GroundControl Coilovers and the Cattman Coilovers and how hard are either to install...
I was thinking of getting the GC Coilovers and Koni's.
Will they work together or is there a better choice? I also was thinking of going with the H&R or Eibach springs and the Koni's any help would be of great help...
One more thing I was also wondering where to get the aluminum flywheel, UDP and some other mods for HP/Torque for a good price.
Thank you in advance...

Coilovers are ideal for serious track/autox racing. Why? because 1) it lowers the car to an agressive setting (correctly with the help with camberkits) so that the center of grativity is lowered, 2) with the correct dampening and spring ratings, body roll is nearly eliminated, creating the ideal control environment.
Ground Control Coilovers lower the car about 3 inches, but don't have the built in struts like cattmans. GC's standard spring settings of 400 pounds is a bit much for daily driving and many many people have experienced hard bouncing.
why i like cattman's coil-overs: they're fully adjustable dampening and height, the ride on them is awesome! and if you really want the handling, they're the best option.
tho it's got the hefty price tag, of those who have them say they're pretty damn worth it (Alex, Skimax, etc. etc)
as for the Aluminum flywheel, that would be good with a stage two clutch... as for UDP, i've heard that gives a "noticable" gain but it might screw up the A/C... (?)

Email from Cattman!!!
Here is the response I got from Cattman when asking about GC's Coil-Over and the real Coil-Over system:
Made a lot of sense...hummm time to save some money for the real coil-Over system:Where is Tein at???
There is no basis for comparing the Cattman coilovers with anything that GC sells because they don't have a shock that should even be used with a coilover system. All they have are Tokicos, and they are inadequate to the point of being nearly dangerous. Konis, when they were available, worked but were rough as a cob, far rougher and less adjustable than the KYB AGXs that I use (exclusively) in the Cattman Coilovers.
The suspension I sell is top notch in every way -- significantly superior to the Ground Countrol hardware in my opinion because we machine almost everything ourselves and control the specifications -- but what sets it completely apart from anything else on the market is that we've figured out how to integrate a fantastic externally adjustable strut that is far superior to anything else available. When I say superior, I literally mean that the AGX works well in a coilover application, the Konis (when available) are lousy, and the stock and Tokico struts don't work at all. The KYB AGX struts I use are custom adapted and otherwise unavailable for the Maxima, they cannot be made to work as a stock replacement and are only available with the Cattman suspension.
As far as stiffness, that's up to the owner because my set is the only one that is externally adjustable on all four corners (4-way in front, 8-way in back) and this allows for a nice range of ride settings. Of course its firmer than stock, it has to be to perform better, but I think its a very civilized, controlled ride, and I'm operating at a 3/6 setting. A 2/4 setting is cushier without giving up too much control.
Very few of my coilover customers race, though the ones that do are doing very well, but the one thing that most people comment on is the car's drivability (and performance!) on the street. The strut clearance allows a 2" drop without compromising operation; more than that's OK for shows or careful cruising, but not intense driving. If you enjoy driving, I highly encourage getting one, you'll have more fun with it than any other mod. With a suspension, you can have at least a little fun almost anywhere because you can't get a speeding ticket when going the speed limit -- no matter how sharp the corner -- as long as you maintain control of your car.
