    Default How to change wheel PCD? want to fit different stud pattern rims

    Hey guys,

    im looking to get a new set of rims for my MPS 6, and i am dead set on fitting the 2010 HSV rims, if anyone isnt familliar with them, these are it:



    Now, problem is, the MPS is (i think) 5x114.5 PCD.
    the HSV wheels are suited for (i think) 5x120 PCD...

    how can i adapt this to suit??

    thanks

    Change your hubs to 5 x 120 PCD

    Then yiou get to change your rotors and brakes as well.

    You would also need to consider offset. I think holden uses lower offsets, so that in itself shouldn't be an issue.
    I'm not sure how you'd change the stud pattern, but it's be a significant modification to the hub etc. perhaps there's the possibility of having a custom piece machined.

    It could be a _lot_ of work....presuming you can adjust the PCD and the offset is practical, then you need to consider clearance; these wheels are going to need rolled/flared/pulled gaurds to get them underneath...

    Some of the Euro cars run 120pcd. maybe look for hubs/brakes simular to the mps

    You can get hub spacer/adaptors. They come in a variety of wheel stud patterns. You can go from 114.3 to 120 (both patterns need to be 5 stud)



    The issue you have is offset. Mazda run a +45 to +50 area. It's hard enough trying to find rims to start with at that offset.

    Adding a spacer/adaptor will increase the track 25mm/side. You can't get +75 offset rims.

    You can go the other way, +25 offset vehicle (eg early Ford etc), fit adaptor, then fit +50 offset rims.

    Thanks for the info troy,

    i knew this sort of thing existed, but i also know that its defect-able in NSW...

    not only that... but ive heard of too many stories about how peoples wheels have come flying off using these bad boys! :S

    cant put the MPS at risk!!! i guess the job is just too big thanks for the info guys!

    That was my next answer......too risky

    As i read on forums that changing the PCD via adapters or spacers = wheels coming off..

    Glad we could help..

    Its ever so slightly possible to weld up the holes and re-drill them.
    BUT
    risky, doubt anyone would do it, and the holes will be in funny spots (through the spokes)

    Most realistic option if you really want it, is wait until that series of HSV is discontinued, copyright will be up and companies will be allowed to rip off the design. Might get some in the right fitment then.

    This was popular with a number of Datsun Z owners (240/260 mainly).

    They have strange offsets which, when combined with a 4 stud pattern severely limit wheel options. So a common fix was to replace the hubs with Ford or Holden 5 stud hubs. Also gave a massive range of brake options

    Woked with a guy who had the same issue Dan, but with a KE20 Corolla.
    Plus he needed better brakes for rego (had CA18DET)
    Had Nissan Skyline strut bottoms with hub, brakes etc. Cut and shut onto the stock Corolla tops

    You could go to a similar wheel too, I remember seeing a set call "Mantis" that looked basically the same. Can't find them now for the life of me, but this is close:
