5mm is so little why bother? I do not generally like to do things on my car that alter the suspension geometry that the factory spent hundreds if not thousands of engineer hours developing.

It wont alter any suspension geometry, just change the offset off the wheels slightly.
It not like he's putting 40mm bolt on version on...... Oh wait that was the Factory on early 930's.... .

That’s my NB with 7mm spacers and hollow spoke wheels (8J/10J). I changed to 5mm longer studs to have more threads with Al lugnuts. Not a hard job with the right tools (didn‘t want to hammer them out)…;-)
Dug out those 5mm spacers…been on the shelf since I got the Tramonts built in late 2013. Unknown manufacturer, likely bought from a fellow Rennlister back in the day, since I don’t have any receipt for them.
New are $60 a pair…asking $75 for the set of 4 shipped.
After looking at many pics, I decided on 10 mm rear and 7 mm front for my 991.C4S. If you proceed, don't worry too much about sourcing the spacers themselves and don't overpay for them. But do worry about the 20 new lug bolts you need to buy. The lengths have to be correct, you need 14x1.5 thread, 19mm head (not 17), and the spherical washer has to have a radius of 14 mm, not 13. The correct bolts can be $10 or $12 each from a dealer source. I sourced mine from ECS Tuning. Also be sure to re-torque to 118 lb-ft after 100 miles or so. New bolts will stretch.
I have used 7mm spacers on front on all the air cooled 911s I’ve owned but on the rears I only use 7mm spacer on left rear. The right rear typically sticks out further than the left and 7mm on left almost evens it out.

I had 5 mm on the rear with no need for extensions bolts. This last year I went with 10mm from FVD they include extension bolts that are needed If there is a deep bump in the road the rear wheels will brush the outer well Works for me
