Hello

I hope to have racing shocks up front.:idea:

Bilstein:crazy:

Keep in mind these shocks are oval track shocks.

Bilstein SG series. 7" 36mm (1.42")

I drilled a small hole in the bottom of my worst shocks I had.
Careful shocks are under pressure.

I then cut the shock top off. Used my cut off saw.
Cleaned it out

I then drilled A 1/2" hole 1/2" down from lower bracket top.

Drilled some weld spot out.

Slid the shock body in. I used electric tape on the end to make up the space.
So shock won't rattle around.

Bolted in place with a grade 8 bolt & poly-lock nut.

Removed the other Eye bolt end. Assembled the spring as normal.
Still looking for another upper nut. (lock nut) it's finer than 10mm 1.0

:wiggle: :wavey:
:zbeer:

I started with this:
<a href="http://s180.photobucket.com/albums/x88/tbirdtess/Mobile%20Uploads/?action=view&current=Photo0252.jpg" target="_blank"><img src="http://i180.photobucket.com/albums/x88/tbirdtess/Mobile%20Uploads/Photo0252.jpg" border="0" alt="Photo0252"></a>

Then this:
<a href="http://s180.photobucket.com/albums/x88/tbirdtess/Mobile%20Uploads/?action=view&current=Photo0253.jpg" target="_blank"><img src="http://i180.photobucket.com/albums/x88/tbirdtess/Mobile%20Uploads/Photo0253.jpg" border="0" alt="Photobucket"></a>

finished with this:
<a href="http://s180.photobucket.com/albums/x88/tbirdtess/Mobile%20Uploads/?action=view&current=Photo0254.jpg" target="_blank"><img src="http://i180.photobucket.com/albums/x88/tbirdtess/Mobile%20Uploads/Photo0254.jpg" border="0" alt="Photobucket"></a>

They are in. will be racing Saturday

Do you have the dimensions of that shock? Part #? I've very been seriously thinking about doing something similar!

Great job! I definitely look forward to hearing how they perform :)
X2 we need more info :D

Nice, let us know how stiff/soft they are. Don't know if that matters on'a Oval track, but what happened to your spring insulator?
The upper shock(Strut) mount looks like its on is way out! :zwall:

spring insulator

:wavey:

I left it off. Can't hear sh!t @ WOT!

These aren't T-bird springs either.

The shocks are way stiffer than the Koni's I took off.

The valving is 5.5

Plus I added camber. Makes the sway bar off center.

SG series

:wavey:

I bought them from Day Motorsports.

Bilstein S7G- 5555

They seem stiffer than the Koni's I took off.

The springs are from a 85 LTD II. They were broken So I helped my buddy change them.

I can't use lowering springs because I have to raise it to 7" ground clearance.
Racing rule.

Thread stuck for innovative design.

I hope to build a set of these for my car some day. Since the Koni's are history.

BTW Paul, what are your plans for the Koni's that you took off? Might they be for sale???

7's are too tall.

:wavey:

Opened the hood today & saw the shocks were sticking about 2" or more
up above the spring.

So anyone with a lowered car maybe the 6" version.

I am going to more the shock to the lower hole.
Closer the the shock base. ( my first hole)

I lost the nut on the RF.:thumbsd: I think it's 11mm but with a very fine thread.:zdunno:
finer than 11mm x 1.0 :diablo:

:wavey:

You would have to go to Bilstein.
I don't quite understand the valving numbers.:rant:
Also different series use different numbers.:zmonkey:

That way anyone interested in doing this..

Have all the details to make this Mod "work properly"..



Good Luck!

Just got off the phone with Bilstein. They were able to get valving info for me. The original T-Bird Bilstein fronts (B46-1505)were 730 compression/1090 rebound. Rears (B46-1506) 650 compression/1460 rebound. The Cobra Bilstein HD rears 800 compression/2170 rebound. He said that you can order the SG series with any valving you desire.

I might see what it would cost to have the SG series built with the original (B46-1505) 730 compression/1090 rebound valving,
Im sure if you do the math someone could figure a good match for the cobra Bilstein rears, as our frontends are heavier then the Cobra. Hence those front rates wouldnt be accurate if compared to T-Bird fronts.

Okay I did some math(thank god for google) If you are running cobra HD rears a good match would be 896 compression/1620 rebound for fronts. I figured this by comparing the ratio from the original Bilsteins for the T-Bird. My math is rusty so give a little wiggle room.

The fronts would be closer in weight to a Cobra for a PI swapped Tbird with the AL block vs the iron block.

I have the Cobra Bilstein rears on my car and I'm very happy with them.

Cobra Bilstein Rear Shocks

Correct me if I'm wrong but you're running:

Vogtland Lowering Springs..
Sport Front Shocks
Cobra Bilstein (Sport) Rear Shocks


What is the "feel of the ride" with your set-up on Dippy Roads?
103973004-GettyImages-172474981.530x298.jpg


In most cars I've driven..Once you get up to 80+ Mph..

It feels like you're floating on the road, and the suspension starts making "squishy sounds"..lol

What is the "feel of the ride" with your set-up..Once you get up to 80+ Mph on Dippy Roads?

I like the feel of a car firmly planted to the road..

Thanks

The one thing that I would add to the (obviously) design. Make sure you incorporate a boot or dust shield over the rod so that it doesn't come in contact with dirt or debris from the road.

Yes, you have my set up correct. To clarify I have the 1.6" drop Vogtland springs with poly spring cups in the rear, the front is as you said (sport shocks with the vogtland springs). I have replacement rubber OEM top shock mounts in the front.

I also have a 1.25" ADDCO anti-swaybar in the rear with the stock anti-swaybar in front.

I certainly wouldn't be doing 80+ on the road pictured in your post. :tongue:

The "feel" of my car on any road or track is very responsive. I feel all the imperfections in the road surface - not that that's a bad thing - the suspension telegraphs the contour of the road surface to the driver very clearly.

The suspension I have is very, very tight. No wallowing in the corners, no "squishy", soft or floaty feel. The car goes where I point it and, to use another cliché, "corners on rails!". I really need to get more supportive seats and they're on the long range mod list.

It's truly a canyon carving performance suspension set-up and is probably way firmer than most people would be comfortable driving. Having said that, I have taken the car on many a road trip and even to a road course. The car is drivable over long distances but you'll need to stop to stretch your legs and scratch your butt more often than if you were driving something with a softer suspension.


I don't daily drive the car and probably would be miserable doing so. But, for a weekend warriors car it's simply amazing.

If you're looking for the ultimate canyon carving suspension you could either mirror what I've done or talk to our resident T-Bird autocrosser Kelsey Smith to see what he's done with his cars suspension. I don't think it's much different than mine except he has lower 3.27 gears and matched 245/45 tires vs my staggered 245/45 front and 275/40 rears. We both have trac-locks in the rear diff.
