OK, here's the deal. I have a set of 15" Kosei K1 wheels with 205/55/VR15 Kumho 712 tires that I have been running on a 96 Mazda 626 that has 5 x 114 hubs. Last week I purchased a 92 240sx with 4 lug hubs. I've been reading the NICO forums learning about the car. As with many newbies here I am wondering if I'll be able to make my current wheels fit the 240.
It looks like I have a few choices for converting to 5 lug. I'll either go with the full Z32 brake setup or just get the front 5 lug hubs from jspec.com (Attain hubs) and go with S14 rear hubs.
My questions are if I go with the Z32 brakes will my 15 x 7 Kosei K1 wheels with 38mm offset clear the Z32 brakes? Also, will the centerbore of my wheels fit the Z32 or Attain hubs? I don't know the centerbore of the wheels that I originally purchased for my 626.
BTW, these wheels and tires were originally purchased from Tire Rack. I can't believe that the Kosei K1 wheels is being discontinued. Why?
Thanks everyone,-VA240
15" Kosei K1s on my 92 S13 240sx?
You don't need to get z32 brakes when changing to 5-lug. The parts needed on the front are an s14/s15 hub and bearing, s14/s15 spindle, and a s14 LCA ball joint (because the s13 lca ball joint is too small and deemed unsafe in the s14/s15 spindle). The ball joint will press into the s13 lca, no prob. So don't feel the need to get 'bent over' by jspec.com...just do a hybrid 5-lug w/ out z brakes. You'll also need your rotors drilled to 5-lug.
I doubt the 15" Kosei's will clear the z-brakes. Also, not sure about the center bore. Maybe the tire rack guys can shine some light on that subject. Also, according to Grant and Luke (last I heard at least), Tire Rack can still get you Kosei K1's...maybe getting a properly sized set (your offset is high) and selling your currents would be the best option.

I've been reading some more about this issue and know I'm thinking about possibly getting the Signal front hubs and a set of OE S14 rear hubs.
Do the Nissan rear hubs come with wheel bearings or do I have to order bearings as well? It looks like I have to order hubs and bearings from Nissan in order to have everything. So my parts list would look like this:
(2) Signal front hubs w/ bearings.(2) OE S14 rear hubs.(2) OE S14 rear wheel bearings.(2) S14 front brake rotors + pads(2) S14 rear brake rotors + pads
I still don't know if the centerbore of my current Kosei K1 wheels will fit the Nissan hubs. According to optauto.com the center bore of the S13 is 66.2 and the center bore of my 626 is 59.5. I do have plastic rings in the wheels now. I wonder if I will just need new plastic rings.

I'm not 100% sure, but I believe the Nissan hubs do come with the wheel bearing. Actually, IIRC they only come with the bearing included and can't be purchased without them.
As for the front rotors, you'll need to redrill the 4-lugs or get ABS calipers and s14 5-lug rotors. Reason is because all 5-lug s14's had abs (I think), and abs 240's have different sized rotors/calipers. ABS brakes are slightly larger. So unless you have an abs s13, you'd have to get them redrilled.

Redrilling center bore and add 5mm spacer?
Now I'm wondering if I could get away with getting a local machine shop to redrill the center bore of my 15x7" Kosei K1 wheels to fit the S14 hubs and also run a 5mm hubcentric spacer to bring the offset of the wheels to +33.
Would this work well and still be safe? How much should I expect to pay if I want to get the center bore redrilled for the 240sx hubs?
Thanks again,VA240

To remove material from the center bore and use a spacer is not a good idea especally on a wheel like the K1. They are very specific about the design of the mounting pad on those wheels. They are designed and machined by Kosi to use the minimum safe amount of material to keep down the weight. Removing more material from the mounting pad is just not a good idea. It is going to weaken the mounting point of the wheel and you are putting a spacer between the wheel and hub of the axle on top of that. Not a good idea in anyone's book. Sell them and get the correct setup for the car.
