I dont know if this is front AND back set to 120KGF or if she is talking just the back. I responded asking if that was for both front and back or just rear. waiting for response.

From Jude:

"120 KGF. To go higher would stretch the CK flanges. We calibrate all our gauges in house so it's an accurate 120KGF. A lot of LBS' seem to have ambiguous accuracy because they have no way of calibrating."
