Thenorm's Rally-x build.
I've dabbled in rallyx before, but now I'm going to convert my Focus to a rally-x car, since I bought a Mustang GT for my autox fix.

This was the starting point.

step 1, remove and sell Mustang wheels for something a little narrower. (fender flares are coming off too)

step 2, buy cheap SVT shocks struts.

step 3 spacers for the front struts.

This was the protoype. these worked quite well.

next was aluminum. final version was 29mm thick.

I had to indent the back side to get enough travel on the shocks before bottoming out, and still not coil bind.

step 4. install spacer/strut front and Wagon springs rear. I now have 7" ground clearance under the SVT header (a notorious low spot)

These are the tires i plan to install as well as my skid plate.

I will also install mudflaps.

Team dynamics pro race 1 15x7" clears SVT brakes. gravel rally tires.

the skid plate is custom made 3/8" aluminum. for an oil change, its just 5 bolts. to remove.

the uprights that bolt to the front subframe, using exisitng bolts on the tie down point and radiator mount.
the captive nuts that I insert into the subframe, so i didnt have to drill holes.

i've been through 3 progressively larger pieces of angle iron for the cross piece. as I keep bending them. the current largest one i had to notch to clear the SVT header.

just random thoughts here...

this is the ST suspension 0.8 inch "spring distance kit" that I based my spacer off of.

coincidently ,the indent in the back of my spacer was 0.8 inch, so on both the ST and my spacers, the bump stop is in the same relative position. and would have the same travel (SVT struts on stock zx3 springs)

in total I have 6" total travel from full droop until the springs coil bind, but the bump stops should bottom out (compressing 2" down to 0.5") in 5.75"

Awesome build! I was sad when I first saw you were selling parts but this is a great reason to be doing so!

Great write up!!! Looking at trying something similar with my mk3 suspension wise

Another well thought out build.

Love the spacers, and wagon springs for the rear is simple genius.

but hold that thought on the wagon springs. although they are tall, they are also stiffer than the fronts, so sometimes i get a bit of a donkey kick going over some bumps. I'll probably stick with it for now (i dont have regular stock rear springs) but i may consider regular springs with a spacer. however the spacer is a little more complicated than the simple cylinder i turned for the front, so I need to think on how to make it. I don't pretend to be a machinist, im just a hack.

Interesting deal you got going on, sub

Sounds like more damping time at the rear then, and maybe more stiffness at the front.

Subie never solved the hatchback's issues in flying compared to the sedan, so weight & balance comes into that part. Donkey kick should be able to be tuned out easier though, separate problem.

More damping for sure, balancing the stiffness in the front would help, but I'm trying to be cheap with the Svt dampers.
I've heard that ranger springs might fit so it's a idea I need to investigate
