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!!!

Very cool. Wish I would have known someone was looking to build one... As mine is now for sale mostly prepped. (Baby on the way...)

Anyway, race today... But I've learned a lot this year and can certainly save you some time. I'll try and get on tonight to answer all your questions.
