Rim Offset
Hey I was thinking of getting new rims, 19×9.5 in the rear and 18x8.5 front, can someone help me with the offsets, I want the rear to have that concave look an I want front and rear to be overall flusher

Front: 245/45-17 on 17x8.5 rim / offset: 58mm
Rear: 275/40-18 on 18x9.5 rim / offset: 68mm
C5 Z06
Front: 265/40-17 on 17x9.5 rim / 54 mm offset, 7.2" backspace (182.88mm)
Rear: 295/35-18 on 18x10.5 rim / 58 mm offset, 7.9" backspace (200.66mm)
Use this program to punch in the new sizes to calculate the offsets......
