Ok about to buy a socket set. Are the CL nuts and bolts metric sizes or english?

Size of oil pan drain plug?

 

The ones that I've encountered are all metric.

For some reason I think the OEM wheel lug nuts are not, but I may be wrong. I've since swapped them out for aftermarket tuner lugs that came with my new wheels, which are 17mm and metric. You'll probably need a separate socket anyway (long/thin) for the lug nuts.

If I remember correctly, the oil pan plug is 14mm, but don't hold me to that

 

thanks slimey... A japenese car made in Ohio. Was not sure what to expect.
