My GN currently has the stock 15x7 rims on it. Cant remember the tire size car is not with me as I'm typing this. I'm having an LS swap done to it with new trans/rear-end/brakes ect...! Pretty much a restomod when done. Trying to figure how much larger tire I can go to in the rear with out notching or rolling the fender. I was thinking of staying with the 15x7 rims on the front and increasing the rear to 15x8 with a wider tire, I not sure what the offset is/would need to be. I like the stance on the 15 rims. Looking for your knowledge/experience that many of you have had with this...Thanks for all replies/pics...!!
