Same offset, so probably? Might take some figuring to get the tire size right to fill the wheel well properly while not causing rubbing, but we'll get those answers soon enough. Hopefully, the 20's are as resilient as the 19s and not as fragile as the 21s.
Thats good news! Hopefully everything works and we can get the look of the 21" wheels with the durability and dependability of the 19" wheels. If anyone has done/does it please post photos and your thoughts on how they perform.
