Default wheel studs

For my rear wheels on a Turbo 911 1989
I have 1 3/4" wheel spaces that I want to put on car but what size studs do I need
They will replace the OE ones where I had the 1" OE spaces

Thanks for the help

The Porsche Parts and Tech Ref Catalogl says stock should be 72mm. Part number: 901 331 671 01 for years '76-'89.

An inch is 25.4 mm, so you'll need about 3/4 that or 19mm added to your existing 72mm studs for a total of 91mm.
