It turns out my Noltec bushes are dead - they are kind of crumbling away, I am guessing it is a shot of degreaser that I used a little while ago that didi it (so much for them looking shiny blue!). Anyhow, the run down on a replacement so far is as follows (looking to get the car on the road i.e. no adjustment).
Nissan don't sell replacement bushes, they sell replacement contrl arms - $432 for both sides
I called UAS, John sais they are supplying Superpro adjustable bushes (SPF1659K) now (not Whiteline like on their website) - $260
UAS also supply Nismo bushes - $360
Supercheap supply the Superpro non adjustable bushes (SPF0723K) - $283
Nolathane non adjustable bushes (45142) are being sold by Online Performance Autos on eBay - $126.72 (plus postage) http://www.nolathane.com.au/product_detail.php?part_number=45142
Whiteline are selling an adjustable set (KCA336) for $355.70 http://www.whiteline.com.au/product_detail.php?part_number=KCA336
It seems like it's going to be hard to pass up the Nolathane option at 1/2 of the cost of the next cheapest option; is there anything that I need to look out for e.g. I can see that some kits come with bolts, which the Nolathane kit doesn't seem to have - will my existing bolts work (normally I woudl assume so, but I wonder why bolts are supplied with some kits?)
Thanks, Ben
