On the later wheels , the 15 x 7 ralley wheel trim ring does not fit correctly.
The center part of a 450 wheel is actually a 14 inch wheel center in a 15 inch ralley wheel band. So the ralley wheel trim ring fits the ralley wheel band correctly.

Later 15 steel wheel bands are 13.25 inside.
The 15 inch ralley wheel band is 12.25 inside.

So there is no way it looks right or fits right.

That's why the wheels are so special.

Also I sell the same 450 wheels as Tony , for the same price.
