4x108 15" wheels- cheap

[blarson at Zeiss.com]

A good (cheap) substitute 15" wheel for a 4kq, 80q, or 90q would be Saab
900 wheels, from approx 85-88 (approx 15 holes around perimeter).  The
earlier 80-84 wheels are not quite as strong (approx 30 square holes around
perimeter), and the Saab 99 "soccer ball" wheels are extremely strong, but
the hole in the center of the wheel is smaller and they might not fit.  I
have seen Saab wheels on Rally cars including the Arietta 4ktq race car.
Good luck.
