S12 Weld-on Coilover Conversion - Adjustable Suspension for the S12.
Written by Justin Carter

The following is a write-up of the coilover setup we have come up with here in SoCal. Engineered and tested by us of the Low.XII.Position crew, it is a for sure way to lower your S12 without converting to the S13 suspension. It is what I am running in addition to Andrew (demonic_s12) and Sterling (sterlingps12). The only difference between between our S12s and what Sterling did was that he used S13 tubes in the front. It can also be verified by Colin (draconis) who road passenger in Andrew's car last year.

In the past many months there have been much interest and many emails inquiring as to our suspension setup so the following is the list of our suspension setup.
This setup allows one to retain the factory S12 tubes.

You will need a welder and a grinder as the front tubes must be sectioned 40mm shorter to accept a shorter SW20 shock. Also, once can use S13 camber plate and in doing so, inform Techno Toy Tuning that you will be running S13 camber plates with SW20 AGX socks and they will send you two small collars that will slip onto the camber plate to take up the slack. They are aware of the situation, so do not worry about their confusion. You will have to grind off the stock perch and weld the Ground Control perch in its place. Other than that, the necessary steps for the modifying the front suspension.

For the rear, the setup is easy and literally drop in straight out of the box. The Mustang Foxbody struts however will require some shimming. To do so, one will need four washers on each shock on the lower mounting bracket on both sides of the car to take up the slack.

Very well thought out and takes out the guessing game on which parts to buy from where. Super legit. Your the man Justin!

LOW.XII.POSITION FTW!!!!

Stickied.
$882 before shipping though.
Kinda pricey for something that needs to be assembled.
BUT! It can be bought over time. That's nice.

And please, if you could, change it from being all caps? It's kinda ugly and a lot harder to read.

I understand everything except what it means to "section the tubes by 40mm".

tommy · 04:46:43 PM / 06-Jul-11

remove 40mm from the total length of the tubes between the perch and the spindle...

Great write-up. For those who want to get the basic idea of what to do take a look at what they did on a corolla

That video cleared everything up. Thanks SlickS12.

hey eightysix, do you have any binding issues? hows yours setup between the upper seat and camber plate?

BoostedVG · 10:09:34 PM / 06-Jul-11

This is the exact set up I run and like alot. Bart did my fronts when he was still around and I got the rear set idea from ModMaster. This info is already out there but not simply put in one thread like this. Nice job!

silvia love · 10:40:56 PM / 07-Jul-11

x2 maybe just post dimensions of the parts needed?

8SixS12 · 08:31:38 PM / 16-Jul-11

Part numbers instead of links would be better but otherwise, this is serious write up! Much props EightySix!

Arro · 04:44:32 AM / 17-Jul-11

A good write-up, but even though he screwed some people over, we need to give Bart the credit he is due, because he did this years ago, and Sterling got the design from him:

Sterling took a trip up to Idaho to see his setup and found out what he needed. But yeah, Bart is the one who sorted it out. Interestingly enough, my RS-X had the same kind of setup on it using a Ground Control kit w/ Eibachs, albeit crudely done.

I second the motion for adding part numbers so we can hunt for more than one vendor for these things.

sam31183 · 02:22:25 PM / 17-Jul-11

for the shocks....

92 MR2 Front Shocks (Part Number: 765015)
96 Mustang FoxBody Shocks (Part Number: 743021)

you can use either the 96 style or older mustang shocks as they are almost identical anyways...through most places i found the newer mustang shocks where cheaper though and that is why i went with them for the canuck/agx set up.
