Legality of aftermarket 17" rims for D3

Wheel specs are as follows:-

Offset = 53mm
Stud (M14 x1.5) hole (x5) PCD = 120mm (M14 = 14mm; 1,5 = one ane a half turns twist for the stud) (x5 means 5 studs)
Mounting face diameter = 163mm
Spigot bore diameter = 72.63/72.56mm (for a vehicle spigot diameter of 72.5/72.47mm)

But this does not mention the "X" factor which is a an approximate measurement of the clearance required for spokes to clear the brake calipers, small, medium and large is the best explanation I have yet had. The D3 I am told is large so what is the D4 (extreme?), please correct me if you have more current info.

PCD is Pitch Circle Diameter which is a circular line drawn through the center of the studs.

M14x1.5 means the largest diameter of the thread is 14mm as stated, but the 1.5 indicated the width of the thread in mm - also being the distance between the tops of each thread - ie turn the nut once and it will advance 1.5mm

Otherwise known as the pitch...

Hi Graeme,
Thanks for the update. :BigThumb:

I look forward to hearing of further progress.

Best Wishes,
Peter

Hi Tombie,
Thanks for the feedback. :BigThumb:

Do you know where such adapter rings can be obtained?

Best Wishes,

Update update. The Performance BB-6 Rims are now, finally, being manufactured with a legal offset (+45), legal load rating (1400kg) and a legal amount of turns per nut. Make sure you specify all three at the time of ordering and reject any rim that does not comply.

who is selling them and how much?

I'm going to have to put my mod hat on here and request you search the forum, or even any of the current threads and you'll see that question well and truly answered. Please do this before asking questions.
