[762CAT]

Hmmm I can't help you with offsets. I know what they are for the Cat but I will say the Hellcat rear rotors are 13.4 inches so a bit smaller than yours. 17inch rims barely clear but they do. 18s (which I run on the strip) clear very easily. I would be confident 18's would fit over your rotors but based on the above 17's are unlikely.

I'd look at what tire you want to use to as that may influence your rim choice. For example the 305/45R18 Mickey Thompson ET Street R that I run and that so many others use with great success is made to go on a 10inch wide rim. Not so say it won't fit other widths but that is the measuring rim from Mickey Thompson. Most 305 DOT drag radials on 20 inch rims are made for 11 inch wide rims. With the manual car I know you are looking at slicks...but it's worth seeing what tire size/rim combo then you can figure out the offset for the correct rim width........

I'm not sure if that helps or adds more math and work....Lol


You are stuck with the problems of being the 2017 ZL1 pioneer unfortunately.
