I have the oddball setup... light wankel, shoved way back in the engine bay. I'm going to probably hav 45/55 setup (guesstimating, could be wrong, but at least 48/52). It's a midengine setup since motor sits behind the strut towers/ crossmember.
So you guys have an idea how far back the motor is. Bare rotary motor without turbo and manifolds is about 200lbs. With transmission a little under 300. I'd estimate turbo, radiator, IC, oil cooler, piping, alternator, and misc stuff will add on another 150 lbs.
My old setup with the L24 was:
-GC coilovers, Eibach 10" springs, 200lb/in all around.
-Tokico Illuminas
-msa 1" front sway bar
-autopower rollbar bolted (not welded) in with 2 extra bars (jmortensen's old unit)
-unsprung weight consists of toyota vented 4x4 setup.
-car was lowered about 1.5-2", strut housings are NOT sectioned.
My new setup is going to also incorporate a ST 3/4" sway in rear with 1/2" offset spacer (already installed).
Now, I did some research and found out (courtesy of johnc) that my mistake was having the same spring rates all around, and this created more or less an odd rebound effect that I experienced on some bumpier turns
A while back I picked up a pair of hypercoil (i think? they're blue) 10" springs in 175lb/in. Can I run hypercoils in front, and 200lb Eibachs in rear? Is there a reason I should not mix them?
I think the Z will weigh about 2200-2300lbs when it's back on the road. I tried to leave as much weight on the crossmember as possible by mounting the motor in the front to the crossmember directly.
What should my spring rates be? The car's a weekend driver/road course/autox in that order, weekend driver being used the most.
