No.Willie isnt that just stiffening the whole car without changing the understeer bias?
When you lose grip on a round a bout do you over or understeer on your set up? I only have a rear Arb fitted , front is stock but the car is very balanced. It will just about understeer first but a quick flick will bring oversteer.
If i was adam id do the rear first and see what it feels like.
Having 25/25mm the car oversteered controllably a lot more. What changed this balance is when you start putting on rear struts and spacers.
