Will look into the differentials but the money isn't there at the moment. Spoon collars have been in a while now they definitely changed how the car feels, adding rigidity and aiding alignment - both great improvements - however the biggest advantage of them was the increase of feedback through the wheel and car asa whole, on road conditions etc.
A friend who'd driven the car previously made the comment that it felt dead, that the car was in control and he was just there suggesting where it would go. After the collars he found it to be not only more alive, but that he had a greater feel for what it was doing. It's hard to explain but it's definitely made an improvement.
Regarding my random list (hehe) I've run DBA before and as a compromise between street and track found them to be excellent. This car may turn into a daily at some point, so i'm needing to think about longevity too | Will consider Ferodo for next set - had the MX72's recommended by my mechanic/guru who really knows gt-r's
Can you suggest camber arms and roll bars? Car has a lot of bracing from factory and haven't found rigidity a problem but could look at it At close to 160,000k i'm guessing the mounts are close to flogged, so nismo mounts seem like the go here - especially given the price of standard!
Car has 'difficult' suspension at the moment - can't seem to get the balance right - it seems to bounce a lot, yet the rear diffuser will bottom out when driving on normal 100km b roads here in NZ
I figure I want to spend my money on the good stuff handling wise to try to mitigate some of this. My last ran bilstein shocks with tein springs - non adjustable - firm but good setup and a good balance between road and track driving, which i'm hoping to achieve again here.
Thanks for the input guys - muchly appreciated!
