My car has 302mm front brakes with std vitesse 4piston calibers. And rear disks are 290mm and rover 800 calibers.
I have got wilwood adjustable balance valve and settings/limiting is 0%
I try first use original sd1 balance valve, but rear disk brakes dosent lock at all even if i drive at sand road.
Then i remove the original balance valve and but the wilwood system, and best setup in my car is zero limiting setup. Now rear brakes lock on sand road, and if i drive about 60miles/h asphalt road and press brake pedal in the floor. My front brakes lock first..
I have got Koni adjustable suspension (hardest setup)
