Hi,

 

I'm looking at some refurbed RX8 wheels, in black, that are local to me and a good price. Is / has anyone else run these rims? Any pics?

 

As far as I can tell they should fit.

 

Cheers!

the pcd is the same, the bore is slightly bigger at 67.1, so you will need some spigot rings, not sure of the offset, Funky or Joely can clarify that lol

Offset and Size. RX8 wheel offset causes a lot of confusion. Here is a simple explanation. If the rim is 8 inches wide, and the mounting surface of that rim (backside of the bolt holes), is 4 inches from either outside edge, that rim has a 0 offset. To the extent that a rim's mounting plane is offset from that zero position, that offset is measured in millimeters for Japanese cars. The Mazda RX8 factory 18x8 inch wheel has an offset of 50mm. A 40mm offset choice is moving the track wider by 10mm per side. RX8 owners looking to stick to stock width can consider any of the offsets we offer here, but RX8 owners looking to go with substantially wider tires should stick to our 45 to 48 mm choices. For those looking to mount maximum tire width for autocross or track events see our 45mm 18x9.5 RP-F1 alloys which are lighter than stock wheels but allow 265/35, 275/35 and even 285/30/18s to be mounted on all four corners of an RX8.

 

You need to know exactly what offset the wheels are that you are buying.

No mattter what car they came from.

Hmm, didn't realise things got so complicated. I figured as long as the PCD was the same and the offset was enough to dear the caliper, then all was fine. I've looked up spigot rings, and wondering why the bolts wouldn't just align the wheel centrally, one tight?

A 50mm offset on an 8 inch wheel is very 'weak' on a 300. My father happens to own one and so I could try a wheel on for you to see what it looks like.

 

The offset says it will probably need a large spacer to fill the arches, 20mm at least

You would be able to drive it theoretically but you are placing your life in the fate of a few bolts rather than having the wheels fixed to the hub properly as a single unit. if you imagine the weight of teh car is essentially being supported by the shaft of the bolts. You will also find it is hard to balance them and you may get some shudder in breakign or at speed. All in all, just not worth it!

 

You can get rings to push into the allow wheel for a few quid from ebay which will do the job. Just make sure that they fit all the way inside the alloy wheel. If they extrude outside of the alloy then the wheel wont sit flush on the hub and you will again be relying on the bolts alone to hold the wheel on!

Thanks everyone, but after all that I think I'm going to give the wheels a miss. I was also looking for a wheel and tyre package, and although it works out about £200 more expensive, the wheels will fit properly and they'll be all brand new! Just means I cant get them just yet.

 

I know a lot more about wheel fitment now! :)

 

Cheers!

The RX8 wheel isn't even nice to me. They would look wrong on a Z. Much like the Jade R wheels which I think dont suit
