Rear %'s averages

[LateModel B23]

What are common rear % numbers when running AR-KK704's and a USMTS/USRA spec motor? This is a 4 bar Shaw running pretty much book setup and getting 56.2% average. Driver says it is a bit tight on entry and then gets really loose from the center on off the corner(s). My thoughts are the 56.2 is causing the tight in and then when he gets on throttle the momentum of the rear weight is causing the car to become loose.

with our car we are up around the 57% range 4 bar GRT spec motor. if i was you i would try to loose up the entry leaving the middle and exit alone and see if that fixes you middle off issues. most like having to use the throttle or brake to much to make it turn in and that already has the tires broke loose of traction.

High rear percentage takes balance away from the car.

my thoughts are the driver is breaking car loose to turn, there for the car is loose in middle and off, with no traction.
fix tight entry, and see if the rest of the corner is better.
