Aftermarket alloy wheels
Discussion
Why is it so hard to get a decent choice for AM fitting? I've seen a load of nice wheels that would suit. Excluding the 'far east' manufactured tat, unless you're going for pretty much bespoke ones, we're pretty limited.
At first I thought it was the high positive offset that would limit the choice but it seems that's not the case. Take the rear of the V12V, its offset is +68 which is quite high, combined with the 11" width means there are few that provide this until you look a little closer. It seems that Porkers (Cayman/Pana fitting) have the same/similar offset of 65mm. The difference is the bolt PCD which on AM is 114.3 and the Porkers are 130. And there are loads of wheels provided in that fitting. OZ is a good example, and they make some nice rims. All available in PCD 130 only at those sizes.

Maybe it's because the wheel manufacturers create wheels in metric dimension for the fitting and not the old 4 1/2" PCD that Aston Martin still use.
I see the logic in still using Imperial measures when we STILL use widths and diameters in inches, but the rest of the world has moved on in that respect.

Not really. The other very common PCDs still being used are 4.25, 4.75 and 5.00 inches converted to metric equivalents, so I don't think metric has anything to do with it per se. I believe that 100 and 130 mm are true metric sizes.I see the logic in still using Imperial measures when we STILL use widths and diameters in inches, but the rest of the world has moved on in that respect.

Certainly I'd subscribe to that if there was a significant difference between the specs. But its the same casting/forging, same everything except PCD.
The holes aren't cast or forged, they are cut on a CNC. Wouldn't a few G code changes pay for itself when you open your market to AML cars?

Companies like HRE and ADV.1 will make you a set if they already do the offset/width. As you say its just a case of a different bit of coding on the machine for that aprticular operation. I'm sure they charge handsomely for it, but they definitely do it as there are V12Vs out there with HREs and ADV.1s

The question was about mid-market wheel suppliers like OZ, not the boutique brands which obviously will make any wheel you want.Gassing Station | Aston Martin | Top of Page | What's New | My Stuff
