My only qualm with the WM Ti bolts is they only seem to offer the black in standard length. I wanted black but needed the extra length for spacers so I wound up going with Acer Racing Ti bolts.

I bought mine directly from adaptec, 10mm front and 15mm rear. More photos here: https://rennlist.com/forums/997-foru...l#post14604242

I just placed an order for 8mm front and 15mm rear spacers with extended bolts from ECS tuning. These look to be good quality and the price is tough to beat.

I will highlight that only Rennline has the proper 7mm hubcentric spacers available. Everyone else claims to be hubcentric (true) but does not extend the hub for the wheel to mount on concentrically:

At 10mm and above you're pretty much guaranteed to have a lip built into the spacer. I could not get rid of a flat 7mm spacer vibration and it bugged the **** out of me because the wheel, even with torquing bolts down in the right sequence would never be truly concentric with this spacer where there was no lip.

I don't think that's entirely correct. 7mm from RSS have a built in lip, and it goes all the way around, unlike the Rennline 7mm.
