Alloy Wheel Fitment

[BDM]

Hey guys, Currently have 20inch Neptune's but toying with the idea of changing them for the summer. I'm useless with fitments but from googling I can see the below however what offset do I need to be looking for? Also anything else I need to be considering? (I am also running spacers at the moment with my Neptune's).

Front 8.5J x 20"
Rear: 10.5J x 20"

Many thanks all

Add this to what you have and you have all you need.

PCD:	5x114.3
Center bore:	67.1
Offset:	52
Mounting:	Bolt - 14 x 1,50

What alloys are you looking to change to? OEM or 3rd party ones?

 

[BDM]

Aftermarket and keep the neptunes also.

Thanks Zep for the above.

is the ET52 positive offset? I think it is.
Have a change at some nice 20" wheels but they might have zero offset. Suspect that any zero offset wheel will almost certainly clash with the camper on my 2006 QP

 

[Zep]

Yes, positive. If it was negative it would all look a bit MadMax.

good news - I have just bought some portofino wheels for my QP.

Let's hope they actually fit. Unless they look awful in which case they didn't fit.

The rear ones fit for sure - the front offset is only few mm different so expect these to fit.

There is even better set of brand new portofino rims on offer https://www.ebay.co.uk/itm/163695738077

For info the portofino match the PCD and CB
Offsets are 51 and 47.5
The bolt length for rear seems a good match. Are they made in the same shop, with just a minor edit to the DWG?

Probably. For bolt length, as a rule of thumb, you need between 1 and 1.5 diameters of thread engaged for the correct strength. So 14mm for an M14 bolt.

Staggered that a full set is less than one GS wheel!,,

Awful isn’t it? Cannot find the proper sport GT 20” front wheel at all.
Thought this might suit. Almost wish I’d bought the other set which are ‘brand new’.

When you get them can you put some photos up please?

keen to see what it looks like

 

[rs48635]

so they do fit..........

 

[rs48635]

there is another set on the popular auction site

 

[JJbing]

Yep most Ferrari wheels will fit! I had a set on my last GT from a 488

The first pic seems to have much less arch gap.

Interesting look - I am not 100% sold on them but given the price difference can see the appeal.

Was a purely practical choice. Needed replacement front for my Sport GT 20" and none existed. Didn't want either M139 18" or 19" options as my tyres are all in good shape. Next best option Maserati option was the bog standard GranTurismo 20" but much preferred the look of these.
The arch gap might be camber on road surface or suspension settling. The car wash is close to garage that swapped my wheels.

Calipers are lost. You need to paint those.........
