Raised Subframe... ride height suggestions

[markfluko]

So I have recently installed PBM solid subframe risers in my s14, and I am unsure on where I should put the ride height at for the best suspension geometry for grip... Just looking for some suggestions. The car is used mostly for autox but will be seeing more track time at TWS.

All SPL adjustable arms in the rear, and the car has an LS1. Any guidance would be appreciated.
