Hi Mike,
How have things been going? Have to admit at the Farmington Pro in 2013 (was there in my '67 Camaro in STX) I remember seeing your car and thinking to myself "Hmm, a 370 would be fun in STR" - year and a half later, I have one, and am looking at STR prep.

Some questions I haven't seen clearly answered elsewhere, though there's still more research to do-

Kinetix front upper arms can get enough camber with a little modification?
Are any rear arms needed to get camber where we want it once lowered (something like -2 to -2.5)?
Does the Uprev Osiris tuning capability close the throttles faster on lift? With the stock computer it seems to wait half a second to do so when you lift, which as a right-foot-braker, messes things up sometimes.
What parts are needed to run 2.5" diameter rear springs with ride height adjustability in the rear? And what length spring assuming rates in the 700-850 range as a starting point?
Is the 1.5-way OS Giken "the way to go" or has anyone found benefit to another option - either 2-way, 1-way, or another brand?
Any "must do" bushings besides the rear diff?

Not trying to muck up your thread, just thinking we can keep this the place people go for 370Z-specific STR info.

Thanks!!!
