I've thought about spacing the subframe down - it's a viable option to raise the body of the car, but it doesn't raise ground clearance. Also, you might want to add spacers under your engine mounts to raise the engine back up in the bay - otherwise it'll put undue stress on the radiator hoses, wiring harness, exhaust hangers, and the torque tube will be at an angle.

Actually, I'm wrong - spacing down the subframe won't raise the body up... that's dependent on the spring perch on the strut. Spacing the subframe down just changes the location of the inner pivot point of the control arm (and you'll also need a spacer for your caster mounts).

Modify the front control arm rear bushing/mount for additional anti-dive?
Early WRX's had soft springs but lots of anti-dive in the suspension geometry which was good for dirt. The modern ones have taken out most of the anti-dive but have stiffer springs and compression damping for tarmac. Very similar McPherson strut setup to the 944.

V2, educated guess only: 25.5"
That's around 3/4"-1" taller than stock.

Hmmm, the tire I measured must be off spec. Good to know!

Does Wilson have an LSD? That should be the first thing on the list if you don't.

Ceika makes a set of rally valved coilovers for the 944.

Their 1M setup is only about $1500 with rally valving and "extra lift" springs, 2M with external reservoirs is $2300. I'm not sure that price can be beat without going through a bunch of custom work to make other parts work. For light rally on back roads you aren't going to need a ton of travel. Even ground clearance shouldn't be too big of a deal unless the road is deeply rutted.

For tires I'm running Federal 195/65r15 gravel tires. If you drive the car on the street avoid gravel rally tires though, they are awful on the street and howl something fierce. A lot of the rallycross guys in the stock class that can't run gravel tires run winter tires that have blocky tread which would be much more streetable.

After reading your post I looked up modern stage suspension and noticed the steer axle springs were on an angle for anti-dive. Great idea!

Determined new tires will be 27"-27.7" ish diameter. BFG KO2. I tend to destroy sidewalls and these are tough & sexy (but heavy!!). I might burn up my old rubber first though since they are taking up valuable garage space. And money is sacred.

Yes Sir, I upgrading to an "S" with oem LSD that works alright. With the 944only short shifter, it's pretty dreamy.
For me, my priority is clearance to protect the turbo crossover pipe/oil pan, front control arms. I have had to negotiate through ridiculously deep grooves which hardened from mud to concrete-like material (one wrong play and it's over)... really too much for a passenger car to be expected to drive through, and I've had competitors had to get towed away because engine oil pans and CV's destroyed... but mighty Wilson made it through (only because I knew when to slow down and how to pick lines off road). It was after a couple of these TSD rallies I started thinking I could be faster with an SUV because of extra clearance.

Cut off the end of the torsion bar tube.

I have been researching stuff online until I'm dizzy... feel like I'm in a daze. Cannot find what I want. Feeling frustrated with findings.
Then something occurred to me. Jeeps use 5" springs. Jeep TJ is a light sporty vehicle. So I search weight.
2005 Jeep TJ Gross weight: 3200 lbs.
1988 944 turbo Gross weight: 3000 lbs.
Later, I bought what I wanted and couldn't find: LONG TRAVEL PROGRESSIVE 5" COILS.
Check these beauties out!

Can someone please recommend a tip or two to assist removal of the TB with the use of a slide hammer through the body hole?

I put a hose clamp on the neck of the torsion bar and loosen it up on the inner splines. then wiggle and spray. pad the hose clamp so it wont nick the bar.

you can tap the end of the bar to vise grip adjuster threads as there is a slide hammer adapter for vice grips.
