I remember a member in another thread said that they stick out about 0.75" more than the stock sport wheels. So total track width increase would be about 1.5".
Step 1: clean all that crap out of the sunroof tray.
I had this same problem when I first purchased my T4R. If you close the sunroof and pour water around the sunroof seal you'll be able to see where the water is leaking into the truck.
As others have mentioned clear the sunroof drains of any...
In Seattle and interested in these wheels.
Just wanted to clarify something, you say -12mm offset and 4.5" of backspacing, but -12mm offset equals 4" of backspacing. Can you confirm if the wheels have 4" or 5" of backspacing?
Also, is there any damage to the 4th wheel? Don't care about paint...
