Advise taken from each of you...

Here is my plan:
- Bilstein B16 pss10
- Will be installed and setup by professional, highly respected track shop; including corner balancing.
- May consider different springs (linear vs the progressive that come with Bilstein) next season. I want to do one step at a time.
- OS Giken with high capacity Diff cover...will research further on the cooler

The owner of the race shop has driven my Z and is familiar with my current abilities.

Any advice on what to request / check on during install and setup? Plan is to increase current Camber of -2.75 up to -3.1.

I can offer some MCA Reds ............. USD to AUD is going to make the price attractive, even with shipping.

1 USD equals about 1.65 AUD at the moment ...........

Well. That took a long time...
 

FWIW my Ohlins suspension finally arrived...
