Wheel spacer size for RBV1 Widebody Fenders?
 

Obviously temporary, but what size wheel spacer would I need to get a flush look on my FRS.
RBv1 Front Fenders +45mm
Rear Fenders +70mm (according to shopgreddy)
Current Wheels: SSR GTX01 18x9.5 +40mm
If anyone knows and/or wants to give me a hand it would be much appreciated.
Planning on going with a wider 18x10.5 in the rear eventually but yeah this is just temp.

Do math

wellllllll I would, but I don't know what offset I need in the first place lmao

Are your wheels flush with the fenders right now? If so, how much width do the fenders add? That's how much of a spacer you need. Or, get a 100mm spacer up front and 50mm in the rear.

Do you need me to wipe the dribble off your chin after that spoon feeding session?

going by my math, on stock fenders you should be flush with the wheels you just specified, so you would need 45mm spacers for the front and 70mm for the rear, however running 70mm of spacers is going to put a lot of unnecessary stress on your hubs. so good luck with that. as for wheel specs if you move up to 10.5 you will want about -2 to -10 offset to make it flush.
