Driving without ABS, I think the BB felt similar with GTA, tried 5/5, rear tires easily lock up on R32 GTR stock, this was done with 50% force, then I tried with my usual settings 5/3, pre 2.06 i can trail brake into a corner without the rear breaking traction/slides out, but after 2.06 i can only replicate with 5/2. The brakes do feel smoother now, more feedback than before - especially when cadence braking, transition to lock up and vice versa also similar to GTA.
The weird thing is, in GT5 pre 2.06 I will need BB 6/6 to have the same brake force as GTA with 5/5, tried them on R32 GTR and 370Z. In GTA, both have heavy tendency to lock up tires with more than 40% brake force when braking during low speed entry. I did all my GTA without ABS, its a struggle to not lock up in every corner.
