Cool project! A good template might be of offering a single coaster per wheel style. Could do 4 coasters total, each with a different style (4x1), or 6 coasters composed of 3 styles doubled up (3x2).
Some popular styles that could work well:
Work Meister/SSR SP1
BMW E46 CSL
BBS LM
HRE P40/VMR V710
Volk TE37
OEM M
And some more inspiration from a similar concept (automints)
