In std GTR the ATTESSA PRO was the "Active LSD option" Though this came standard in the 33 GTR VSPEC. This ECU reads 100 times per Second, The ATTESSA ETS which is the older version in R32 GTRs and some 33's Read at 10 times per second.
I dont think a swtich would be to easy as the other main upgrade of the PRO is controlling the four-wheel independent ABS braking system. This is not part of the AWD system, but the ECU makes use of the same sensors to determine wheel slip and traction.
were as the ETS version controls the front to rear torque-split and to also at the PRO is also capable of left-and-right torque split to the rear wheels. This is done via an active rear limited-slip differential.

Just read all 13 pages, not to much mention of the -9's though they seem to have a totally diffrent opinion on -5's.
Main jist here seems to be -7 or -9 with stock motor, -5's for a storked engine.
Yet they are claiming to be making boost by 2000RPM and on song by 4k. Non stroked motors.

id assume you will need bigger calipers to accomdtate the bigger rottor, Or an adapoter of some sort. If you going bigger rotors the you might aswll go bigger everything, Much better wheel selection in 5 stud aswell
I just don't get why a rim size can take numerous rubber sizes, is the desicion looks or performance based? A tyre shop will just tell you to go with factory sepc rubber. Not taking into consideration use factors
