Matt,

You might want to also post on SpecialStage.com. Nissan made rally suspension for Z cars there should be pictures on the net.

TRD made rally struts for Corollas and Celicas (ages ago I had Corolla rally car project), the struts had around 8" of travel.

California Rally Series has/had a class called performance stock; springs were free but you had to use stock components but those could be beefed up.

What I would do is bolt on a standard strut from a bigger car like 280ZX or early Maxima and then use modified shackles in the back. After that weld on reinforcing metal to the control arms.

OR

Brace up the standard front struts and control arms, use Z car springs in front with B210 springs in the rear.

The hot ticket on my Volvo 140 Rally car was quality dampers all around with 164 springs on front and 140 station wagon rear springs. The car had no sway bars on it because most west coast rally's run and washboard gravel road and the suspension compliance was more important the body roll. On a street car I leave the bar on.
