Extended Wheel Studs

[RJuans96]

I have bought some new wheels that need 10mm spacers to fit as the centre bore was too smal, so I need some extended studs. What size would I need? I mainly need to know the width of the splines that sit in the hub.
Thanks.

Drill out the centres with a rotary file.

The studs are m12 x 1.25. Nissan and Subaru have the same I think
