I am looking at a set of 18x8.5 Front and 19x9.5 Rear MRR GT1 wheels and they are offered in two different offsets (35 and 45). Can anyone help me with which offset do I want to stay with? I am pretty sure I read where the stock offset is 45 but I wasn't sure if I should keep that since the rear width is 9 1/2. Thanks for any info!!
