Hubs/Boss Adaptors
Works Bell
The most commonly used hub for the Z. It comes with an airbag resistor to stop the airbag light from coming on. There are 2 kinds of hubs made by WB - Standard & short.
Standard - This will position the wheel in almost the same reach as the OEM wheel
Short - This is for use with a Quick Release & also positions the wheel in near enough the same reach as OEM.
Cost £100-£120
NRG
Basically a knock off of the Works Bell hub, I have seen cases in the states of them cracking & you really do not want that to happen
Cost around £100
They are the only 2 specifically designed kits for the Z that I know of, I know that MOMO make one but I'm not sure if its Z specific or universal.
Quick Releases
Nice to have, but not essential. If you do buy one this is where the horn becomes a bit more complex. It will come with 2 small spacers which the horn must be earthed to in order for it to work. I only figured this out a few days after fitting my wheel & I found them in the box & after I already made my own earthing points.
Lots available, mainly by Works Bell & in a variety of colours expect to pay about £200+ for a good one. Again I need to stress the point that you need a good one - If these fail while your driving it not gonna be pretty.
Available as a quick release or flip up release.
Steering Wheels
Stock wheel is 370MM, Most people seem to feel that the 350MM wheel is the perfect size but you can also get a 330MM. Plenty of choice available depending on whether you want leather or suede finish.
Cost from about £80
Tools Needed
small allen wrench (supplied with WB hub)
T30 tamper-free Torx bit
small flathead screwdriver
19mm socket
10mm socket
Andy has written a good guide to removing & refitting the wheel so follow that guide for it
Things I noticed after installation
*Steering wheel no longer locks into place after switching car off
*Can no longer move the wheel without the engine running
*Can no longer rest arm on window comfortably
I find the smaller wheel much more natural than the OEM size wheel & the few people who have driven my car since fitting them have agreed.
A few pics of my set up.
