What spring rate for 2012 WR450F with YamaLink lowering

Rider just called asking what spring rate for his 2012 WR450F Yamaha should he have? Weight before gear is 190 pounds. The stock spring is 5.3 kg/mm and at 190 he will put a 5.6kg and with a YamaLink he'll need a 5.8 spring to lowering his suspension with our link and have good sag measurements and bottoming control.
