Hi,

I'm not familiar with the wheel. Do you know what the original wheel offset was? They varied between + 1mm to +3mm. What are the wheels you are looking at?

Also, and this has nothing to do with this site, but check this out and let me know if you find it helpful.

Let me know.

Take care,

Joe

Note: I wouldn't recommend going much past the original offset on this vehicle.

The factory wheels were 15” diameter x 8” with -13mm offset and 3.5” back spacing. I’m not sure what the current wheels are from previous owner. I believe they are hitting the E brake. Because it was dissconnected. I am looking to go 18” or 19” in the rears and 18” in the front. I want the same deep lip as the car you have in the videos.

Hi,

I understand. Were you able to look through the link I attached? It provides options for the vehicle. Also, this should have rear drum brakes. Do you mean the wheel is hitting the parking brake cable?
