im looking to get a set of wheels for my 510 soon, but i dont know the lug pattern for it. and are there any wheels from stock cars i can use?

4 x 114.3 stock cars include: 240sx (4 lugs), ae86 corollas, honda accords (lower offset tho), and a few others. just dont get it confused with 4 x 100 lug patterned wheels, another commonly mistaken lug pattern

this is sort of an old list but it has a lot of wheels off other cars that will fit a 510

I had some early mitsubishi starion wheels on my 510 for a while.

Keep an eye on offsets tho. 510's can run anything between 0 - +25 offset without any spacers or problems (0 offset could be a little hard tho... but 15-20 is IDEAL)

a +30-40 offset will require spacers and a offset that is too far negative will require flaring of the fenders if your car is lowered.
