Need help eliminating oversteer

xavier

many thanks for those first answers.

I'm convinced that the axle offset improves the rear kinematics for extreme lowering.
It will be a car with extreme settings, but it's a car that must be driven on the streets, and these extreme modifications are prohibited.

I received my 12k rear and 14k front coilovers, but they aren't adjusted or installed on the 370z; they're monotubes with rebound. From my experience with the 350z, which seems to have the same rear as the 370z, the 9k rear was too soft on bumps. Sometimes, rarely, the rear would flatten and touch the ground when there was a road defect while traveling at 50km/h / 30mph. But traction was good.

With a 12k rear, I hope it won't be too stiff. I'm planning on using Hotschkis sway bars, adjusting the geometry with adjustable arms, adjusting the alignment, changing the rim offsets, and maintaining the original tire width. with lift system on the coilovers.


Based on yours experiences:
With approximate values... with 14k front shocks.
What would the rear spring rate be (9k, 10k, 12k?) to achieve normal rear kinematics?
what needed difference in spring rate between the front (14k) and the rear (9k, 10k, 12k?)?

What would be the maximum lowering/drop, or minimum height, at the rear to maintain adequate rear kinematics?
And with what camber and alignment that aren't too extreme?

I'm planning on using the 35mm diameter Hotchkis Front sway bar, with a hard/strong adjustment.
I'm planning on using the 28.5mm diameter Hotchkis Rear sway bar with a light adjustment.
Will the Hotchkis 28.5mm Rear sway bar be too stiff (with the light adjustment)?
Would I need a different rear sway bar?

Thanks
