I guess you mean the wheels, not the centre lock nuts

ltcjmramos

Correct, wheel offsets.

It has been done. PCCBs + centerlocks have been deleted!

ngng

Which size studs did you use? 81mm? Those red nuts from APEX as well?

Wheel offset/backspacing? Which car to select to get the correct wheel?

See post #78 for questions and answers on the stud sizing.....those look like 81mm (the safe bet). I used 71mm with 1 to 2 threads to spare using custom Forgelines with no issue.

All wheel offsets for 997.1 GT3 (narrow body or for wide body) are valid. If you are having custom wheels made you can toss the OEM 5mm rear wheel spacers and build the wheel properly (i.e. for narrow body rear make it with offset 63mm, instead of 68mm).

For those who care... thanks to Mooty to helping with right BBS E88 specs. He may know them better than factory. And some info on the right stud length.

These fit my 997.1RS perfectly, no rear spacer needed:
Front: 9x18 et 50 0288274 ctr (1” and 8”)
Rear: 12x18 et 42 0288107 ctr (3.5” and 8.5”) no spacer

Also, on studs. It seems the .2 centers may have thicker bolt holes, not drilled quite as deep. Hence why Mooty like 200000mm studs (100 I think actually). I have 82mm bullet studs and they are perfect with about 10mm of thread showing front and rear after being torqued. You COULD get away with 90mm front, maybe slightly longer and the bullet nose would be flush with the wheels. however, if I were to do this with OEM wheels it would look a little goofy as the studs would be sticking out. I went with the Tarett studs with MSI nuts this time around. seem much higher quality than Apex. Similar to MSI studs I think but have a nice shoulder to torque into the hub.

Hot tip: clean your hub holes. Go to snapon.com and order a 14x1.5 thread chaser tap for all of $5 shipped. It must be the cheapest snapon product in existence. This will clean up threads without cutting them.

^ tarett studs are made by msi.
msi does both

I had to go to full thread race studs because even 91mm studs were barely fitting the E88s.

mooty

^ ur center is not the same as spyerx.
7.2rs EE88 ctr are much thicker. that's why i run 100+
