Check out the rear suspension of the mid 2000's Subaru Impreza...Very simple design, looks to be pretty light weight as well, shouldn't be too hard to replicate with the existing body mount points on the 944...would need to customize the lower shock mount though.

Mike,
The way you formatted the thread looked like you were asking a question and looking for suggestions. If you would have just posted "Hey, I'm using Lexus suspension to make our archaic suspensions much better!", people would have came in here and said "cool!" and would have just waited for updates.
No need to take offense towards the suggestions and "keep your comments to yourself" irks me, badly. It's very "negative community", and well, a forum is the exact opposite of that.

The main reason for not soliciting comments on the objectives, is that I don't want the thread to get off topic. The objective of the thread is to discuss the technical details of the upgrade I am carrying out.
I agree about the need for a "positive community" approach, and would appreciate help with this.
If anyone wants to debate the objectives, they can start their own thread and move the discussion to there. Maybe that will happen now?
Cheers,
Mike

Might be worthy of another thread? Any takers?

Who's your son? And what are his times? Only for 944S ? (205 crank hp 3.0)

I wouldn't consider $4k to be a very viable price for all of this, since that is cutting into half the cost of a turbo model these days and doesn't account for the rear end at all.
What about just spacing the crossmember down on a stock car? If you can calculate the distance of the drop of the crossmember (say 1/4" drop) then drill the hole up 3/4" on the crossmember, which would be an increase on the pivot of 1/2" on the inside, it might be enough to account for the lowering. From there, it's just dealing with the downward spacing of the rack and having a form of bumpsteer kit on to account for it and the natural bumpsteer of the original system.
Such a kit could be well under 2000 dollars as long as there is a source for used crossmembers (or design a new one?).

There are other threads where people have done this inboard geometry mod (Per Anders for one) including improving the caster mount. I'm treading a slightly different path!

I remember you being pretty tight with West D., ask him who I am and who my son is...
West mentored my son for 3 days 5years ago when he started racing at age 19 as a favor.
Tell him you saw some crazy dude from Louisiana on RL talking crazy noise and he had an old gray 944 as his avatar....
On the OP's original topic, I did see West bust an a-arm a couple of years back, but I'm pretty sure it was the end result to an off....but, realistically, his 944T is running cup car speeds around TWS....at least in qualy.
And in his defense, I'm pretty sure he hadn't mounted his double top secret set of tires yet...
To Tony G, no sweat man, I was just trying to paint a picture that explains that we beat the he11 out of our cars, not doddling around at the back of a DE. I saw a potential deal on your rear suspension sale on here somewhere with Max G (Energy). If you talk to him on the deal, ask him if my stuff is reliable....

T is good people, as is his boy, Eon. Like me, they focus on getting a lot of speed without breaking the bank. In 16 years of running my car I have broken ball joint pins from a couple of different aftermarket companies. I'm interested to see where this thing is going. I have 200K miles on a set of Lexus control arms (on my Lexus). :-)

I'm getting the components from Sewell Lexus in Dallas.
So, I guess you could say I get "all my Lexus parts from Texas" (that's a bad George Strait pun)

Very interesting.
Always wondered why Porsche didn't change the suspension for the 968, like they did for the 964 over the outgoing G-series 911. But I guess that was older still, with torsion bars front AND rear, spindle and strut integrated in the front. They obviously had to change it for the 964 AWD system, but still don't see why didn't redo the 968.
I imagine they left it because of the financial issues Porsche had at the time.
Back on topic. Love it. Look forward to see progress!
So does this mean you now have a Lorsche? A Pexus? Lexorsche? Porexus?
Would it be a good idea to design a subframe that bolts to all existing suspension points along with rear attachment points and maybe more, but design the subframe to use 928 or newer Porsche, Audi Weissach-style rear multilink? Might need to ditch the stock fuel tank.
I don't know if the subframe thing would be a good idea, it would surely exert different forces on the stock suspension points than the stock suspension exerted. I don't know if those points are designed for the different forces a subframe would exert.
JUST a thought. Keep in mind am nowhere near an expert on suspension geometry. (Disclaimer!)
Happy Holidays!
