I'm interested in this. I was looking at the FCM set up and found it interesting, however I have a few questions. I want a full set up, shocks, springs, bump stops, everything. I'm on 50k miles stock suspension and I want to change everything.

I'm on stock power and wheels right now, but that's going to change in the future. Will that affect the revalve specs? (meaning I'm screwed once I make the improvements). I was gonna go for wheels first, but if this is such a good deal, I might as well start with the suspension.

For springs I would look up the sub 1k suspension thread. I think people have good things to say about the QA1 springs and they are cheap. You need to know your future setup BEFORE you buy valved shocks. I'm going to buy the FCM bumpstops. I have the old FM ones, but I know nothing about them. AND you don't hear people raving about their FM bumpstops. You will need to know how the wheels will affect the ride height. Shocks are valved to accept ~ +/- 100lbs, so their is flexibility with the valved shocks when it comes to springs.

Be honest with your future goals. IS this going to be a DD with some track or a dedicated track car. Check my "break down spring rates" thread. Good info about what spring rates work for what. I've got the old FM springs F342/R228 and Bernie told me to keep them for my needs.

You WILL need to pick a spring rate to valve the shocks. Call Bernie for the specific data he will need for the revalve.

Let me know if you want to be put on the list.

Everyone in the group buy should start collecting this information for their order.

"All I basically need from them is a note in the box with a name and phone number. In the note include the spring rates front and rear, sway bar size front and rear, ride height, and their intent with the car."

Obviously if you are not sending in shocks, then you will need to provide this information on the phone when you call to order.

Anyone know what spring rates the SM valving is built for?

I mean, SM is 700/300? or is it 325. But... i'm 700/400... and might go stiffer . Dammit... I think I'd need custom valving.

Are they able to do valving that takes into consideration a car is dual purpose? Street and track day car? What's needed for a dedicated track car isn't nessasarily what we'd want for the street.

Yes, this is what I'm getting. This is why he needs to know what the purpose of the car will be. Exactly what is done, I have no clue.

I asked Bernie specifically if the setup I am getting would still allow me to be competitive on a track (my setup will be primary DD, with occasional DE). The answer was definitely.

It looks like we have enough people on the fence that could swing this group buy into action ASAP and not wait until the 3-14-10 deadline. What's the good word people?????

I'm on the fence whether to send my shocks to them or directly to Bilsteinusa. About the same money either way.

I have heard this too. For the same monies I would go with Steward seeing as Shaikh is sending his customers there and not recommending Bilsteinusa. Plus it seems they know what they are doing.

Example of where to measure ride height. Measure ride height from where the blue meets the black. It is typically the lowest body point.

Will measuring from the center of the wheel to the lip not work? This is the typical way to do it and eliminate the tire's aspect ratio from the equation, No? Not sure how Bernie prefers his measurements.

This info I posted was straight from Bernie. I didn't know where to measure from so I had to ask.

How is one supposed to know ride height when they don't have adjustable suspension yet? I plan to run something around 12.5R and 12F but I don't know what this will be in any other measurement.

Im most likely going to join in on this groupbuy.

An extra note. They offer shock body shortening for 30 per corner for 1". More than that is another 25 I think he said due to shaft shortening and other things.

I'll be doing used shocks... custom revalve and a shock shortening.

Which tophats will you be using? I'm curious because I know there is not much room between the top of my bilsteins and my FCM tophats at about 12.25". I have pics somewhere but I'm too lazy to post them again.

I'm debating whether I want the ISC racing 1.5" hats in the rear, or the shocks shortened. I think both would be too much travel with a modest spring rate. (I want to trade my 400lb front springs for 500-550lb and I run a 300lb rear.)
Not sure about what shock length tophat for the fronts though..

What benefits are their of shortened shocks? I guess it depends where they are cut also(above or below the spring perch).
-Above would net better bump travel correct?
-Below would basically lower the ride height without affecting bump travel or preload?

So it's $600 if you revalve it to SM specs...

Would it be $600 if I want it revalved to SM spring rates for an autox/street car?Survey says, " MAYBE A GOOD DEAL" SPECS... SPECS... SPECS

It'll be shortened from the top. Shock travel is Always a good thing. Plus.... mine will be NB shocks on a NA, so I need shortening anyways.
