Cattman-Progress Coilover Suspension - Intro group deal

In any case, I ended up getting the same tranny as before - non-LSD but I did get the ACT stage 1 clutch and the UR flywheel.
I was looking into motor mounts when I kept blowing exhaust gaskets but cut that project short when I stopped blowing gaskets. The problem was with the cheap Budget Exhaust gaskets.... as soon as I put Nissan ones in there, I've never had a problem since.
Back to the coilovers, are you suggesting that I do not need to have adjustability in the struts to go from drag to street - only spring rates matter? If I have 850lb rear springs and regular 400lb front springs, I can see the possibility of there being massive oversteer in case of any 'situations' on the street. Could I hypothetically run 850lb springs in the front and 800lb springs in the rear, thus taking away oversteer... and still having the stiffness for the track? I know that it would greatly change daily driving by making it harsher... but I might not mind it all that much... will have to try and see... if it is a possibility to run those spring rates all the time to avoid swapping back and fourth.

Hypothetically you could run 850lb springs in the front and 800lb springs in the rear, but in reality this would not be a good choice. The optimal setup for the drag strip is not optimal anywhere else; you must swap the rear springs before and after you go to the track (not that big of a deal, expecially since there are no alignment issues on the rear axle).
If you owned your Maxima solely to drag race, then yes, you'd want to change the damping on your struts (by changing valve rates), but that setting plus the heavy springs is not what you'd want on the street at all.

I would need a hydraulic jack at least, and a 10mm wrench... but anything else major? How long might it take?

I'm not sure about the springs compressor, and the reason for that is that you may be able to screw the spring perch down all the way and take the pressure off the spring so that the compressor is not necessary.

I'm not quite sure about the terminology, but the only parts you would re-use would be 1) the upper strut mount, i.e. the black piece that the threaded end of the strut rod sticks through, that bolts (3) into the strut tower opening (rear mounts are completely replaced by coilover parts) and 2) the little strut bearing piece that goes directly underneath the upper strut mount.

Oh sure, there's height adjustability, just a matter of screwing the spring perches up and down. Maximum height would be about an inch lower than stock, but you can lower them about 2.5-3.0".

The only stock parts that carry over (and this is explained in the installation instructions) are the front strut mounts and the little strut bearing pieces that go underneath them. Otherwise, the kit is complete unless you choose to use camber bolts.

You can place orders without concern that the minimum group deal limits will be met. We'll have at least five orders (qualifying for the $1075 price), but I don't expect there to be 10.
Our order line is open till 5pm MST, 800.759.9920.

Going much lower than that will require more camber (not caster) adjustment, though dropping 1-5" - 1.75" won't. We offer the Progress camber adjustment kit, consisting of two camber bolts for each front strut. These allow far more camber adjustment than camberplates do because they are limited by the small opening in the top of the strut tower. They are also the source of much of the noise that coilovers are famous for -- Progress's coilover system (made for many cars) intentionally avoids that whole camber plate headache.

Do these Coilovers make any noise ???

There's probably no such thing as a coilover set that never makes any noise, but these are the quietest that I've ever operated. The absence of camber plates is a key reason, and those metal-on-metal problem areas are eliminated in this design, but its still necessary lubricate the tops of the spring assemblies with white lithium grease.

Whould Isolator sleeves from Nissan possibly work ?? maybe cut a little section for the top, just to quiet the top spring assembly...

I'm not sure what would suggest otherwise, but yes, this suspension is the essence of a true coilover setup!
There is no particular noise issue about the top spring assembly. Its just a matter of lubrication during installation, I'm not talking about doing anything unusual or damping it with a ton of grease.
Bottom line, these are extremely quiet coilovers and I have an extensive frame of reference to base that on, what more can I say?

just went outside and measured, the front is 1/8" lower then the back. the roof rack makes in look more because it is sloping down. just realized profile is of first height detup 
site will have pic of new profile(sorry about a little foiliage in the way)

I'm pretty sure that everything that's been paid for has been shipped out already.
We carried the y-pipe group deal over till Monday, 27 October, and I'm happy to do the same with the coilovers, but that's it. Price will go back up to $1250, which is still the intro price (regular price will be $1350).
