To keep the same length currently, I'd need 48mm, but the only bolt options I can find are either 47mm or 50mm. I just don't know if 47 would be too short or if 50mm would be too long and put pressure on something within the hub? Which size is suggested?

joe@vwvortex

47mm are the right ones

Also is it correct to assume that ALL aftermarket wheels use conical bolts, or could some possibly use ball seat bolts? I have Axis Decade wheels.

Thanks again.

Use 12mm "Tuner" lugs. Standard are 14mm and won't fit on some models. Best to check. They are usually conical to my knowledge, but check..(on left)

Does going to 12mm effect it fitting the hubs on the TT?

The studs have 14mm threads where they mount to the hub, then 12mm the rest of the length. Wheels are retained with Nuts. There is a pic (14mm anyway) at the link below..<ul><li><a href="https://forums.audiworld.com/tt/msgs/1581493.phtml">https://forums.audiworld.com/tt/msgs/1581493.phtml</a</li></ul>

Is that the link you meant to show?

I just don't understand how to determine whether the bolt is 14mm at the hub side. Also, any idea where to get these?

Also I'm adding spacers, so I would need 43mm and 48mm bolts in the correct length.

TIA.

Ooops!...Fixed!

But your wheels are likely drilled for 12mm studs. Maybe someone with some experience on these will chime in. I know CdnTT has them on his car. Fixed the link above too...
