Hub & Knuckle interchangeability VA STI to GD STI

merlin6014 · 11-20-2023, 04:51 PM

Anyone done it?

Ive measured the front and rear hubs and they are identical measurements. Also one site even slipped up and mentioned same part numbers.

Knuckles Ive collected a lot of part numbers and I have a theory they are the same (front for sure), rear I have doubts.

Why do i want to do this? As I have all the VA stuff but also hope it helps someone as GD STI part prices are through the roof and VA can just buy over the counter.

Front knuckles work, I have a set of GR STI front knuckles on my Bugeye WRX. VA WRX/STI knuckles are the same. ABS might be an issue, but I deleted my ABS long ago. The rear knuckles are a different design. If you want bolt in hubs for the rear knuckles, TSSFab is really the only option.
