Nissan Z Performance '23 GT4 Replica Tuning - need some advice

[CodeRedR51]

So I have driven this car A LOT in GT4 replica form. Through several online leagues, custom races and time trials. I have never had a tune as good as the one posted below. It suits my driving style very well and the car handles amazing. BUT, it still has a small issue with a nervous rear under hard breaking.

Looking for a crew chief that can set me straight on how to fix that. I can dial more front brake balance into it to bandaid it during a race, but want to know if there is a way to permanently fix it.

NOTE: the power and weight in this tune is specifically set for a custom Sophy series I am running.

BUT, it still has a small issue with a nervous rear under hard breaking.

Try increasing front Natural frequency, as you're braking the weight is being flung forward so the rear gets lighter hence the oversteer feel, along with that the stiffer front springs will now make turn in a little harder/more understeery so you may want to lower front compression 2-4clicks to compensate for the stiffer springs

You might as well try to just lower the rear camber angle, as when its too much, the cars get mega squirrely on braking
