Mozambique Truck Rims by Black Rhino

 

Hi Bill, do you have any pics of where to shave fins? Only on front caliper - so backs fit ok?? thanks in advance.

 

There is also an option from Lucky8 now.
They also have some videos (instagram), that show minimal material being removed from the calipers so they fit.
18" Steel Rims that fit without spacers and they look great!

LR4 18x8" Steel Wheel Set of 4 ? Lucky 8 Parts and Accesories for Land Rovers

 

I would not recommend those Chinese made metal wheels. It's worth paying more and getting something much better such as the Compomotive wheels to compliment your LR4. No modifications needed and they were built specifically for the LR3/LR4.
