I figured if Porsche brake swaps have been done, some one must have looked in to the wheels. Although it seems like width difference may be too large. So it may not be worth the effort but it's half the price of custom sized Volk or Work wheels.

Size: Front: 19x8.5", Rear: 19x11"
Center Bore: 71.6
Bolt Pattern: 5x130
Offset: Front: +56mm, Rear: +51mm

I ideally want to run 275 and 305's. I can get a lug conversion but the minimum spacer is 15mm. I can't find info on swapping the hubs. Would an aluminum lug spacer work for the bolt thickness difference? I would also need a hub ring.

 

Bolt pattern is all wrong.

 

Sourcing wheels that are made to fit an FD will most likely be cheaper while also causing less headache.

Bolt pattern is wrong (a big one), centerbore is wrong (would need adapters), and they are not light weight by any means. 19s on an FD is not a good idea IMO.

If you're looking for some very nice custom fitment wheels, shoot me a PM

 

I know the bolt pattern is wrong, that's why I mentioned the adapter. I found a company that does it in aluminum, so it's pretty light or as light as the spacers on my Z. I know the bore is off and would reqire a hub centric ring (easy fix). I can get those wheels and tires for $2k, so that's half the cost of Volk or Work custom fitment.

Main concerns:
+15 spacer changes front to +41
+15 spacer changes rear to +36
Width difference is more than two tire sizes.

That is the reason I had the idea of spacers to convert 130 to 114.5. Unless i'm understanding the numbers wrong. Are the holes (or studs) for the 130 larger then 114.5?

So I know a hubcentric ring would reduce the bore but would using spacers to make it lug centric work or am I not understanding the 130 to 114.5 part?

Oh wait, are you saying the Porsche Turbo wheels are not light weight? ...damn!

Well, I have a set of Nismo wheels I bought for the 7 but since I don't have a turbo I slapped them on the Z.

 

I know someone selling those wheels and tires, pm me if interested.

 

Imho, those sizes are not desirable, the difference in width between the front and rear is too great and will make for a poorly balanced car if it is used on a circuit course.
