wheel bore sizes

Hi, please can someone advise the various wheel bore sizes on 4 x 100 pcd MX5’s?

I know one model = 64.1mm but not sure which one that is or if there is a difference at all between the 4 x 100 cars?

 

cheers in advance.  

 

Hmm, my wheel database says 54mm diameter for all 4x100 MX5s. Certainly my mk1 is 54.

Fitting wheels with a larger centre bore is easy and safe, if done right (I have done tens of thousands of miles like this to prove it, including high speed track stuff and hundreds of wheel changes)
