what is the minimum ride height in california?
can clutches and flywheels work for auto transmission cars?
oh, and does an lsd require any fine tuning or adjustments after installation?
btw, what is the stock ride height on a 2003 350z(in inches from the ground...)

actually as a general rule dictated by physics ur vehicle should not be lower than 4 inches, is just how gravity & force, moments etc. dictate it should be. Clutches & flywheels can be integrated with automatic systems but serve only one purpose racing. Take per example the new system that the evolution will have twin clutch transmission, currently Volkswagen has a twin clutch version that uses on the Audi. Both r atomatic but in reality the only purpose is reduction in shifting times which equal faster gearing. The result racing machines.

-the ride height is as low as u feel u would be safe in a crash but if u want a number around 45''

--a automatic transmission uses a torque converter that works like a certifical clutch u hit so many rpm is & the pressure causes a gear change
all cars have flywheels the flywheel on a automatic bolts to the torque converter
you can put a automatic behind a manual but u can not put a manual behind a automatic
well u could but the gearing would be very tight to make it pointless & u would have to install a clutch behind the auto
where as in a manual/automatic u could shift the manual & there by change the rpm range on the auto behind it(through the flywheel/tq converter setup) changing the shift points & the overall output rpms of the output shaft in a smooth motion ie

i have done a manual/manual have never done a auto/auto & tried a manual/auto but never installed it(the assembly was huge at almost 8 feet long)

---nope once a limited slip is in & the mesh is correct u just need to watch the fluid & seals & change the fluid from time to time 5yr/60k
usually when u replace the fluid u should check the backlash & mesh for proper placement by using white grease & moving the assembly a rotation & adjust as need be but for the most part just keep the levels up

goodluck
