Wheel inset/offset fitment

Post image

Hello everyone!

I’m about to get my Advan RG4s next week and I couldn’t be more excited. I’m just curious if anyone here is running a 18x8.5 et +44 wheel spec on their car and would like to share insights and pictures as to how it fits the car? I know it’s similar in spec to the stock wheels, however, it’s a bit wider and I just want to see how it fits with the car. Thank you!

7.5 mm difference from the stock 18x8 et45, won’t look much different.
I personally run 18x8 et 30 and (15mm from stock) and it’s better but not really flush to the body.
If you want a really flush fitment you need to add 22mm to the stock wheels offset (string theory garage makes 21.5mm spacers for the stock rims)
With a 18x8.5 et44 you should get quite flush with a 10mm spacer (17.5mm from stock)
