Likewise, one of the best transmission upgrades is by PPG. Guess what, PPG are Australian.

I love what Puddy is doing and if it wasn't for freight I would be all over it. Instead I found a highly regarded Aus diff (and gearbox BTW) specialist and worked with him to upgrade my diff. There is no OS Giken or Kaaz center. The Torsen unit is fine and not the part that fails. I supplied a new crown wheel and pinion and the specialist had new end caps machined and a steel collar turned. The result is a diff that nicely holds the power my car generates. Took 9 months but the results are impressive so far.
This guy look after people in melb? wonder how much would cost to send my diff and gearbox to sydney and back LOL!.
