My ride had 5 lug adapters installed when I got the car, just got into taking the rear suspension off yesterday and took adapters off for the first time. My 5 lug bolt pattern is about 115 mm, so not standard Porsche 130 mm pattern. The adapters used one of the original holes in the hub for a longer stud, then had 4 others pressed into the adapter. How do you get 115 out of 130 using one of the hub holes ???
There I fixed it, sorry for poor proof read.

here's how, an offset stud. Anyone seen any of these befiore? Spacers are 21mm thick and die cast, no idea who made them.

Terrifying.

You need to throw away you metric measuring tape. 315mm = 12.4" Bolt pattern and 121mm = 4.7" thick spacer.

Offset studs are an old cheap way to change wheels around. I would not reuse them. They look scary!

315.....AROUND.

Metric all the way!!!!!!!!!!!

315 = 115 + typo.

Offset lugs weren't uncommon back in the day - I think they're still available, at least in the LBC world. Never heard of any problems. Of course, normally you'd use 4 or 5 to change to a different lug layout.

it's too bad that they didn't just keep the 130 mm bolt pattern, then no fancy offset stud needed. Guess lots more wheel choices with the 115 (or so) bolt pattern.
