Got new front wheel hubs. Ordered from Nissan USA but made in Sushi land. Part number is 40202-4M405. Pretty fab casting quality.
Rears later. Also got NSK wheel bearings. Figured I might as well change the wheel bearings when I press out the original 85K km hubs and wheel bearings. You can order the wheel bearings from Bro Nick over at the MY N16 forum. If you need his contact lemme know.
I also ordered aluminium alloy rim centre hub rings to replace the stock plastic ones. These are from Ultralite Wheels in the UK and are forged 7075 aluminium alloy. All N16s and B15s use a 56.1mm hub centre. My Work Emotion CR Kai is 73.3mm as can be seen below.
The Ultralite centre hub ring that fits is the one from 66.1mm to 73mm. Part number is self explanatory - YD-HR73661A. Comes in a pack of four. Ultralite does not sell direct but you can easily get these from eBay. Available in any colour so long as black. Picture of the centre hub rings. Looks loads better than stock sunkist orange if you ask me.
Am still undecided whether to go for a slightly wider front track utilizing 10mm wheel spacers and longer wheel lugs. H&R make pretty decent ones that are a direct fit and with the lug pattern I want (4 lug 114.3 PCD).
